Channel Groups can be set to Off, Trim/Fader, or Fader. Trim/Fader groups allow the smallest channel number in the group to control trim, fader, record arming, limiters, and mutes of all channels in the group. Fader groups act just like Trim/Fader groups but trims remain independent per channel. Groups that are Off retain their channel routings but settings and levels are independent per channel. This allows for quick enabling or disabling of a group without losing group routings. Trims can only be grouped when all channels of the group share the same gain range. Gain ranges depend on input type routed to a channel. See Channel Screen>Channel Trim Value for more detail. Four channel groups are possible; channels grouped can only be assigned to one group.
Note: When the optional +4 Plugin is installed, channels 1-12 are available for grouping.

Record Folder
Record Folders are containers for storing recorded audio files and sound reports. They can be nested up to three levels deep. Set a record folder as ‘current’ to determine where audio files and sound reports are stored.
Record folders are unified across all three media (SSD, SD1, SD2) - any actions taken on a record folder (NEW, SET CURRENT, Delete Folder, Create Sound Report) affect that record folder on all three media.
To select an existing record folder or to create a new record folder, go to the Take List and use the */** toggles to access the REC FOLDER menu. By default, the RECORD FOLDER menu displays a list of record folders at root. Navigate to nested folders by highlighting a record folder and pressing the Sel/HP knob. To navigate back up the folder hierarchy, press Menu or select “\..” at the top of the folder list. The screen’s title identifies the folder path.
To create a new record folder in the folder level being viewed, select NEW (Tone toggle). The newly created record folder is automatically set as the current record folder. Select the Folder Type in the popup that appears. There are three types of record folder - Custom, Project, and Daily.
Custom
Files are stored in a custom-named folder; the Custom folder name is embedded as Tape metadata in the recorded audio files.
Project
Files are stored in a folder with a name determined by the Project name entered in the Take List > Next take Edit Screen. The Project folder name is embedded as Tape metadata.
Daily
Files are stored in a folder whose name is in the format yyYmmMdd. When a Daily folder is selected, the Date is embedded as Tape metadata.
When a daily folder is selected as the current record folder, a daily folder popup is displayed when the first recording after midnight is completed. The daily folder popup displays the following message:
“Store this recording and subsequent recordings in the previous day’s folder or store in a new daily folder? [Previous], [New]”
Tip: To store new recordings in the root directory, highlight ‘None’ in the Root screen then select the */** toggle (SET Current). When ‘None’ is selected, the date is embedded as Tape metadata.
Any existing record folder can be set as the “current” record folder. Use the SET CURRENT */** toggle to set the highlighted folder as the “current” record folder. The current record folder can be easily identified by the orange “[current]” tag following the folder name.
Tip: To easily find the current record folder when it is nested within another folder, navigate the path indicated by orange record folder names.
Tip: The Record Folder menu can also be accessed by selecting ‘Folder’ from the Take List>Next Take Edit screen. This also shows the current record folder’s full path.
Tip: Program a Toggle Switch or map a shortcut for one-touch access to the Record Folder menu.
Record Folder Options
Highlight a record folder then select OPTIONS using the Rtn/Fav toggle. The following options are available:
Create Sound Report
Creates a sound report for the selected folder (not including its sub folders) on all 3 media. If there are no audio files in the selected folder, a ‘No Takes Found’ popup is displayed.
The sound report’s filename format is [Date]_[RecFolderName]_Media.CSV, where Date is a 6-digit string based on the Date Format setting in the System>Time/Date menu and Media = ‘ ‘ for SSD, ‘_1’ for SD1, and ‘_2’ for SD2.
For example: Rec Folder name = ROLL8, Date = 13th Aug, 2020 would appear as:
081320_ROLL8.csv (on SSD)
081320_ROLL8_1.csv (on SD1)
081320_ROLL8_2.csv (on SD2)
Delete Folder
Permanently deletes the selected record folder and all its contents including sub folders on all three media. This action cannot be undone.
When the monophonic WAV file format is selected (in the Record/Play > Track to Media Routing menu), all mono files created for a take follow the name of the take and are stored in a take folder within the selected record folder.
Take Edit Menu
If a take is renamed and the edit doesn’t conform to the current Filename Format setting (with designators), it becomes a freeform take name and metadata will not be updated.
If a take is renamed and the edit conforms to the current Filename Format setting (with designators), the metadata is updated even after renaming a freeform take name.
If a take is renamed and the edit contains a letter following the take designator, the take number metadata is updated only with the numbers immediately following the designator.
The ‘+’ prefix is added to a filename if an existing take is edited such that it would duplicate the name of another existing take in the same record folder. The ‘A’ suffix is added if the NEXT take’s name is edited such that when recording is started, it would duplicate the name of an existing take in the same record folder.
File List
Menu>Files>File List enters the File List. The File List displays the 833’s internal SSD and SD cards and their contents. Various details of each drive, folder, and WAV file are indicated on the right side of the display: TC, FPS, duration, format, tracks, date, time, size.

When combined with 833, the SL-2 wireless accessory offers integrated control of SuperSlot compatible receivers, monitoring, powering, and RF distribution for multiple channels of wireless audio. Selecting the SuperSlot menu item (or shortcut Meter+HP) navigates directly to the Rx Overview screen.
See SL-2 Receiver Overview for more details.
The SuperSlot menu is grayed out and inaccessible unless a Sound Devices SL-2 Dual SuperSlot Wireless Module is attached to the 833.
The SL-2 Receiver Slot Power or the 8-Series power must be cycled after performing any action that causes a receiver to reboot. Powering receivers on and off from the receiver’s user interface is not supported.
The SL-2 is a two slot-in wireless receiver integration system that easily mounts to the top panel of any 8-Series mixer-recorder. It accepts UniSlot and SuperSlot™ wireless receivers from a variety of manufacturers. Power to the SL-2 and receivers is supplied by the 8-Series mixer-recorder – no external DC connector is needed on the SL-2. Analog or digital audio is sent from the receivers into the mixer-recorder via the expansion port, reducing messy cabling for power and audio connectivity.
The SL-2 offers antenna distribution to slot-in receivers, spreading out the placement of antennas for better RF performance. Additionally the SL-2 allows for control of smart antennas and includes two filtered antenna outputs to external receivers via MCX ports. The rear panel of the SL-2 is equipped with two TA3 connectors for an additional four inputs of AES3 audio and two 4-pin Hirose DC Outputs, each supplying up to 500 mA.
Up to eight channels of audio can be routed from the SL-2 to the 833. The eight channels can be comprised of audio from dual or quad channel slot in receivers and/or the four AES inputs.
The SL-2 mounts to the 833 via the multi-pin expansion port located on the top panel. Please refer to the SL-2 User Guide for panel descriptions and installation instructions.
WARNING! To avoid potential hardware damage, turn off power to the SL-2 slot prior to removing and inserting receivers. Slot power can be turned off in Menu>System>Expansion Port, Menu>SuperSlot>Options>Slot Power, or by powering off the 8-Series Mixer-Recorder.
Supported SuperSlot receivers for use in the SL-2 are:

GainForward (A20-Mini)
The A20-Mini transmitter introduces GainForward, a new feature that eliminates the need to adjust microphone preamplifier gain at the wireless transmitter. Audio levels from the transmitter are controlled directly at the mixer’s trim control. If the talent speaks too softly or emotes too loudly after being “wired” with the transmitter, simply adjust the transmitter gain with the mixer’s gain trim. Read more about GainForward at:
https://www.sounddevices.com/gainforward-explained/
Adjusting Audio of the A20-Mini Signal from 833
When the A20-RX/A10-RX receiving A20-Mini signal is slotted into the SL-2, the A20-RX/A10-RX Input menu settings are bypassed and all gain, low cut, and limiter activity are performed and controlled by 833. See the A20-Mini and A10-RX User Guides for more information.
When 833 is receiving A20-Mini signal via SuperSlot the 833s’ trim gain is adjustable from 0 to 60 dB. The A10-RX Receiver screens display the associated 833 channel’s low cut, audio overload, and limiter activity.
A10-TX does not support GainForward.

Suppress background noise instantly on-location with the optional CEDAR sdnx or Sound Devices NoiseAssist plugins for 8-Series mixer-recorders.
CEDAR sdnx
Over the last few decades, CEDAR has become synonymous with real-time, low-latency, and artifact-free audio restoration and noise suppression. CEDAR Audio Ltd.’s sdnx brings CEDAR’s highly-regarded noise suppression technology to 8-Series mixer-recorders. This optional plugin reduces unwanted background noises so you can better capture dialog.
CEDAR sdnx has near-zero latency and one simple control for adjusting the amount of suppression. Up to 8 instances of CEDAR sdnx are available per mixer-recorder/device. These instances can run on any combination of isolated channels or bus. The plugin functions at sample rates up to and including 96 kHz.
Previously, using CEDAR with an 8-Series mixer-recorder required a separate hardware unit like the CEDAR DNS 2. This collaboration between CEDAR and Sound Devices marks the first time CEDAR technology has been available in-unit for any portable mixer-recorder. Now, even ultra-light portable recording setups have access to CEDAR noise suppression.
CEDAR sdnx requires 8-Series firmware v7.40 or higher. Want to try before you buy? The 2-instance version of the plugin is available as a demo on 8-Series running v7.40 or higher.
Sound Devices NoiseAssist
NoiseAssist is an advanced signal processing algorithm that reduces background noises such as traffic, generators, HVAC noise, and more. The plugins continuously monitor background noise to give you clean audio for the entire take.
Using NoiseAssist is easy and fast - simply adjust the amount of background noise to suppress and NoiseAssist will do the rest. Suppression happens in real time with just 1 ms of latency - no “learning” required. Depending on the plugin purchased, two-, four-, or eight- instances of NoiseAssist can run on any combination of isolated channels and/or any bus.
This algorithm is optimized specifically for high-end professional film and television dialog. It accurately distinguishes the desired speech signal from background noise using proprietary advanced multi-band frequency, level, and statistical calculations. NoiseAssist maintains the excellent frequency bandwidth of the audio channel, while effectively suppressing the background noise and reverberation.
NoiseAssist Plugins are available for purchase at store.sounddevices.com
Try the two-instance version of NoiseAssist Plugin in demo mode (tone bursts replace audio every 10 seconds) until the NoiseAssist Plugin license is purchased and installed. The NoiseAssist demo mode is disabled when the 8-Series is powered down.
Mode
Selects NoiseAssist or CEDAR sdnx and whether Noise Suppression is disabled* or enabled.
The Noise Suppression field in the channel and bus screens shows as NA when NoiseAssist is active and NX when CEDAR sdnx is active.
Note: Set a toggle shortcut or mapped controller button to enable/ disable Noise Suppression to allow you to quickly compare the effect of it being on or off.
Channel/Bus Selection
Selects up to eight (depending on plugin installed) instances of Noise Suppression and which channels and/or Buses it is applied to. If the maximum number of instances are already selected, deselect one instance before selecting another.
Note: Noise Suppression only affects the mix of ISOs and return bus sources when applied to buses receiving audio from L, R, B1, B2 buses.
Note: NoiseAssist and CEDAR sdnx cannot be used at the same time. NoiseAssist is only available at sample rates of 48.048 kHz and less. CEDAR sdnx is only available at sample rates of 96 kHz and less.
Adjusting Noise Suppression
In the Noise Suppression menu, ensure Noise Suppression is enabled and the required channel and/or bus is selected.
For a Channel: Enter the channel screen using the PFL toggle. Use the Select knob to scroll to and enter the NoiseAssist (NA) or
CEDAR sdnx (NX) field. Rotate the Select knob to set the amount of Noise Suppression applied to the channel.
For a Bus L,R: Go to Menu>Buses and select Bus L or Bus R, whichever has been enabled for Noise Suppression. Push the */** toggle to the right to select the NA or NX parameter and rotate the Select knob to set the amount of Noise Suppression applied to the bus.
For a Bus B1-B4: Go to Menu>Buses and select Bus 1-4, whichever has been enabled for Noise Suppression. Push Tone toggle to display more options then push the */** toggle to the right to select the NA or NX parameter and rotate the Select knob to set the amount of Noise Suppression applied to the bus.
Noise Suppression values range from 0 dB to -20 dB with 0 dB representing no noise attenuation and -20 dB being the maximum amount of noise attenuation.
Channels or Buses enabled for Noise Suppression show a diamond in their meters. The diamond moves based on the amount of Noise Suppression averaged across all the frequency bands that have signal in them.
The lower the diamond on the meter scale, the more the background noise is being attenuated. The diamond moves towards the top of the scale as the audio signal changes (for example, when a mic picks up dialog) - this indicates that the Noise Suppression algorithm is learning and adapting to the signal in real-time.
To effectively use Noise Suppression, start with the default setting of -6 dB and dial in more or less depending on your environment. An ideal setting will reduce the background noise without coloring the sound.
Note: NoiseAssist and CEDAR sdnx are not automatically linked when channels or buses are linked.
833 can be controlled from the Sound Devices CL-16 or CL-12 linear fader controllers or supported third-party external controllers that conform to the MCU protocol.
Controllers connect via the 833’s USB-A port either directly or via a USB hub.

Display Ch. Fader Gains
Selects whether the fader gains are displayed in the controller’s display. [Off, On*]
Applies to CL-16 and 3rd party controllers.
Soft Fader/Trim Pickup
[Off*, On] When enabled, physical faders and trims on the 8-Series front panel, CL-16, CL-12, and some 3rd party controllers with non-motorized faders resume gain control only when their physical position reaches the last stored gain value. This prevents sudden jumps in gain levels when setting gains from more than one control interface.
Note: Last stored gain values are held over a power cycle and may require the adjustment of a physical fader or trim control to pickup the last stored gain value.
Note: Soft Fader/Trim Pickup also works in conjunction with the SD-Remote. The 8-Series trim/faders pickup control only once they have reached the last gain set in SD-Remote.
When Soft Fader/Trim Pickup is Off and a controller is connected, the 8-Series front panel controls are disabled unless controlled by SD-Remote. Use SD-Remote Hide Faders function to prevent SD-Remote changing fader gains accidentally.
Note: When a non-motorized fader controller and SD-Remote are both used at the same time, the controller will not soft pickup fader or trim control.
Solo Follows Select
Selects whether solo (PFL) mode is engaged on a channel when pressing “Select” from the controller [Off, On*]. Applies to supported 3rd party controllers and CL-16.
CL-16
Selects CL-16 menu.
CL-16 Operation is covered in the CL-16 User Guide.
CL-16 GPIO (General Purpose Input/Output)
The 10-pin Phoenix connector labeled Remote provides eight GPIO ports. These can be configured as simple contact-closure inputs, and to drive low current draw components such as LEDs and logic-controlled powered relays.
CL-16 Remote Pin Functions
Ground (-): for triggering logic-low connections.
1 - 8: Configurable as inputs or outputs, activate high or low, and assigned a function.
+5 V DC: for triggering logic high connections.
Active High inputs trigger when +5V is applied.
Active Low inputs trigger when ground is applied.
Active High outputs go to 5 V when the mapped function is active.
Active Low outputs go to ground when the mapped function is active.
The GPIO lines can supply or sink 10 mA through the series 100 ohm internal resistance. This is not enough to directly drive relays but is enough for driving logic-controlled powered relays.
Pin 10 of the connector supplies 1A at 5V.
GPIO Outputs can be used to drive LEDs with a proper series resistor. Resistor values vary from LED to LED, 470 ohms is a good starting point.
Although the CL-16 has protection against ESD (static electricity), highly inductive loads (like relays, bells etc) may require extra diode protection to protect against inductive voltage spikes. Make sure to protect the CL-16 with an anti-parallel diode across the coil of what is being driven.

¼-inch jack
Common analog audio connector used as both an audio input and output. When a ¼-inch jack is described as TRS (tip-ring-sleeve) it can be wired as either a balanced connection or as a two-channel connection. ¼-inch headphone jacks are typically wired as TRS stereo jacks.
3.5 mm jack
Common small-format audio connector. Often used for headphones and -10 dBV signals for portable audio devices.
Advanced Audio Coding (AAC)
An audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at the same bit rate.
AES3
A standard for the exchange of digital audio signals between professional audio devices. An AES3 signal can carry two channels of PCM audio over balanced, 110 ohm interconnections. AES3 is most commonly interconnected with XLR-3 cables.
AES42
A digital interface protocol for microphones and microphone inputs. Microphones conforming to this standard directly output digital audio through an XLR or XLD male connector, rather than producing an analog output. AES42 microphones require powering.
Attenuation
A reduction in the level of an audio signal. Attenuation can be applied to both analog and digital signals. A fader is used primarily to attenuate signals, though a small amount of positive gain is often available on a fader.
bEXT chunk
Broadcast WAV extension data added to the audio data in a WAV file. The bEXT chunk includes timecode and user bit data. For systems that do not recognize the bEXT chunk this additional information is ignore
Bit depth
When converting between analog and PCM digital audio the amplitude of an analog signal is measured in finite steps, measured in bits. Higher bit rates result in greater resolution of amplitudes, resulting in higher dynamic range. 24-bit audio, with a theoretical maximum dynamic range of 144 dB, is the standard bit depth used throughout the audio chain for production.
Broadcast WAV, BWAV
Broadcast WAV files are WAV files with additional, non-audio data, such as bEXT chunk data. Broadcast WAV files offer timecode support.
Bus
An audio path that is the destination of one or multiple (mixed) channels. A bus is typically routed to an output, a record track, or both.
Camera return
An audio input on a mixer designed to receive the output, typically the headphone output, of a camera. Camera return inputs allow the user to monitor the level and quality of the signal received at the camera. On the 833 the Aux In can be used as a source for any channel.
CEDAR sdnx™
CEDAR Audio Ltd.’s highly-regarded noise suppression technology is available as an optional paid plugin from store.sounddevices.com. Use CEDAR sdnx to reduce unwanted background noises so you can better capture dialog. CEDAR sdnx has near-zero latency and one simple control for adjusting the amount of suppression. Up to 8 instances of CEDAR sdnx are available per mixer-recorder/device. These instances can run on any combination of isolated channels (excluding 17-32 on Scorpio) or bus.
Channel
A “slot” of a mixer that is controllable and routable. A given input feeds the channel and the channel’s settings process and route the audio as required. It can also be thought of as the path its selected input signal takes on its way to its record track, a bus, or an output.
Channel grouping
With the 833 all of the 8 channels can be grouped together so that their faders, record arming state mute states can be controlled together. Channel grouping can be used as an alternative to sending channels to a bus.
Circled take
An identifying character, the @ symbol, which is placed in the file name to highlight a take. Circled takes can either be used to identify good takes or to identify tracks or takes that will be ignored
Com return
A dedicated audio input designed to receive signals from a PL, or private line communications circuit. The com return on the 833 can routed to an output or a bus.
Com send
A dedicated output designed to send signal to a PL (private line, talkback) communications circuit. The com send is toggled by a front panel switch.
dBFS
A measurement of the signal level of a digital signal in dB increments, dB relative to full scale signal. The maximum signal in dBFS is 0 dBFS, with signals expressed with a negative sign. dBFS signal strength is an internal measurement and does not correspond to analog signals unless the relationship between analog signal and digital signal is known.
Delay (channel)
Time delay that can be applied to an individual channel. Channel delay, typically set in milliseconds, is often used to compensate for different acoustical or electrical arrival times of signals between channels.
Dugan Automix
An automatic mixing algorithm invented by Dan Dugan which when used across multiple microphone inputs for speech, makes decisions about which inputs should be given priority due to speech being present vs. open, but unused inputs. This allows for greatly improved audio by turning down the inputs that aren’t used and automatically turning up the inputs that are being used in real-time and transparently
exFAT
A storage volume format that can be read and written from current versions of MacOS and Windows. exFAT supports volume sizes up to 128 PB (gigantic), and individual files can have a maximum size of 16 EB (even more gigantic, bigger than the maximum volume size).
Fader
A physical control on a mixing console, either a rotary or sliding potentiometer, that controls the level of a channel to a bus. Most faders have more attenuation than gain available and a unity gain position where the input trim level established the level to the bus.
False take
A recorded take that was either erroneously recorded, or a take that needs to be repeated. It can be labeled after recording. An identified false take is moved to the trash bin and the auto-incrementing take number is reset to the value prior to the false take.
ile list
Every file recorded by a recorder is visible in the file list. It can be viewed either on a recorder or from a computer when the recording volume is mounted. The file list shows all the individual files recorded by a recorder.
Frame rate
The rate at which video or motion picture images are recorded or played back, measured in frames-per second (FPS). All audio and video devices must be running at the same frame rate to keep audio and video synchronized. Timecode frame rates are either an integer or non-integer value. Integer values include 24, 25, and 30 FPS. Non-integer frame rates include 23.976 and 29.97, and 29.97 drop FPS.
Frequency
The period at which a wave oscillates, measured in hertz (Hz). Frequencies audible to humans range from 20 Hz for very low frequency signals to 20 kHz for very high frequency signals.
Gain
An increase (or decrease with negative gain) in the level of an audio signal. Gain can be applied in several locations, to both analog and digital signals. In a field mixer the microphone preamplifier provides a substantial amount of gain at the trim to raise the low level microphone signal to a usable signal in the mixer. Gain is also available at the fader. Gain of digital signals or line level analog signals is often limited. Unity gain is gain stage that neither adds or subtracts level from a signal.
Headphone monitor
Often a separate bus with a dedicated headphone volume control, the headphone monitor typically is normalled to the main left/right output bus of a mixer. Headphone sources can often be selected among soloed tracks or buses. In some products complex headphone monitoring of MS Stereo, LR stereo, and ambisonic sources is available.
High pass filter (audio)
Also referred to as a low-cut filter, this circuit reduces the amount of low frequency content in an audio signal. A HPF is particularly useful when recording speech since the human voice does not generate appreciable energy at low frequencies. The HPF reduces non-speech signals such as environmental noise, wind noise, and microphone handling noise, improving the intelligibility of speech and reducing low frequencies from overloading the input. The high pass filter is placed in the circuit close to the microphone preamplifier.
High pass filters are often frequency selectable, ranging from 20 Hz to 200 Hz. HPF also have a slope, generally from 3 dB/octave to 18 dB/octave. Greater/steeper slopes offer more attenuation of frequencies just below the set filter frequency.
Input
The physical connection and associated signal type from external sources connected to a device. Inputs can include microphone inputs on XLR connectors or USB audio inputs from a computer. Depending on the architecture of the mixing console its inputs may be hardwired to channels or channels can be selected from different inputs.
Input limiter
A limiter circuit reduces the peak signal levels of audio, generally to prevent signal overload. Analog inputs have a maximum input signal level that can be reached before overload/distortion is introduced. Setting the input gain correctly so that input signals do not reach this maximum level prevents most overload conditions. In the presence of very high, unexpected signals an input limiter changes the gain of the incoming signal and prevents it from overloading. Input limiters are sometimes compressor-type circuits with a ratio of infinity:1, meaning that any increase to the input signal into the limiter at the limiter threshold does not increase the output signal of the limiter.
Several parameters may be available in a limiter, including knee, ratio, release, and threshold.
Isolated track
A recorded track of an individual microphone or sound source. “Iso” recordings allow for post-record mixing of individual sound elements.
iXML
An extensible data schema for audio and related metadata stored in broadcast WAV files. Manufacturer-specific data generated during recording is stored in iXML.
Line level
An analog audio signal used to interconnect audio equipment. Line level may be balanced or unbalanced, referenced to +4 dBu or -10 dBV, professional or consumer respectively.
Low cut filter
See high pass filter.
Microphone level
The audio signal generated by a microphone. Mic level signals are very low level, requiring a microphone preamplifier to bring them to usable, line levels. Interconnects with microphone level signals can be subject to noise and interference.
Mid-side linking (inputs)
When mid-side (MS) stereo inputs are used and the inputs are set to MS linking and MS decoder is activated for those inputs. This yields a stereo signal with one fader controlling overall input level and control for the “width”, or amount of the side signal added. With an MS matrix at the input, the signal is sent to an output bus as left/right stereo. Mixers with MS matrices often allow for discrete mid and side signal recording. In that case the MS decoder can be activated at the headphone selection to monitor left/right stereo.
MixAssist™
An exclusive Sound Devices automatic mixing algorithm which when used across multiple microphone inputs for speech, makes decisions about which inputs should be given priority due to speech being present vs. open, but unused inputs. This allows for greatly improved audio by turning down the inputs that aren’t used and automatically turning up the inputs that are being used in real-time and transparently.
Mix track
A recorded track that is a sum of multiple tracks. In production sound the mix track is often a single summed track of all production dialog elements. Mix tracks can also be sub-mixes of like microphones, such as a sub mix of just lavalier microphones or just boom microphones.
Monophonic WAV
A WAV file that is comprised of a single track of audio. When recording multi-track audio with monophonic WAV files each track is recorded to its own WAV file, with a file name indicating the track number. All associated monophonic files that are part of a multi-track recording will be identical lengths.
Mute
A mute control is a convenient on/off switch for a channel and an easy way to remove a channel from appearing in downstream buses. Mute an input or channel does not change levels or settings; when channels are muted and unmuted, their settings remain.
Notes (metadata)
A metadata field that is saved along with audio data in a recorded sound file, useful for sound report generation. Some workstation software recognizes the notes field and presents it when viewing the sound file.
NoiseAssist™
An exclusive Sound Devices noise suppression algorithm which is available as an optional paid plugin from store.sounddevices.com. Use NoiseAssist to suppress background noises such as traffic, generators, HVAC noise, and more. The plugin continuously monitors background noise to give you clean audio for the entire take. Up to eight instances of NoiseAssist can run on any combination of isolated channels (excluding 17-32 on Scorpio), bus L, or bus R.
NP-1(A) battery
A specific class of battery, originally developed by Sony. There are multiple chemistries in this class including lithium-ion and nickel-cadmium.
Output
The physical connection and associated signal type sent from a device. Outputs can be source from inputs, buses, record tracks, and other auxiliary signals.
Output auto-mute
When set, an output signal is muted when recording is stopped, restricting program audio from being sent to listeners “between takes”.
Output delay
A digital delay applied at the output. Signal delay is often set at an output to compensate for the delay introduced by digital imaging systems so that picture and sound remain in correct “lip sync”. Output delay is set in either frames or milliseconds.
Pan
When a channel is routed to a stereo-linked bus the level it appears at each bus is adjusted by a pan control. A channel with its pan control “straight up the center”, or “centered” sends signal at the same level to each bus. A channel that is panned left or right sends the signal to the left or right bus, respectively.
PFL, pre-fade listen
When an input or channel is selected for monitoring/solo with a PFL, the channel is routed to the headphone output before the channel fader so that the fader position has no effect on the headphone level. Trim/gain changes to the input will change the headphone output.
Phantom power
Condenser (capacitor) microphones require power for operation. They use power to charge the diaphragm backplate (for true condensers) and power the impedance convert located adjacent to the microphone capsule. Phantom power is the method for microphone inputs to supply DC power to the microphone through the same connection used for the audio signals from the microphone.
Phantom power provides a positive voltage, typically between 11-52 VDC, with 48 V being the most common, on both pin-2 and pin-3 with pin-1 used as ground. The DC voltage appears as a common-mode signal on the balanced connection and is rejected by the connection’s differential amplifier. Phantom power has no effect on dynamic microphones.
Phase
The relationship one audio signal has in time with respect to another audio signal, defined in degrees of phase. When audio signals are generated at identical times, they are “in phase” with each other. When one audio signal is time-delayed with respect to another the signals are “out of phase”. Differing phase relationships can be introduced several ways, including when microphones are placed at varying distances from a sound source, or electrical/digital delay is introduced to one signal with respect to another.
Phrase
A pre-set text string which can be used to quickly fill out the notes field.
Pre-fader routing
The signal from a channel is routed to a bus before the fader in the signal path. The input trim, if available, controls the channel level sent to the bus. Isolated tracks are typically recorded pre-fader so that any level changes made to the faders don’t affect the recorded signal.
Pre-roll
A continuous buffer that is always writing to memory offering a recording that begins prior to when the record button is activated. Pre-roll is set in seconds, and the recording begins the set number of seconds prior to the button being pressed. This is helpful in applications where an operator missed a cue to begin recording.
Polarity (audio)
The direction of the current flow of an audio signal is defined as polarity. The polarity of a signal can reversed when a balanced audio signal connection has its pin-2 and pin-3 connections reversed. Single-ended signals can have their polarity reversed when going through an “inverting” gain stage. It is best practice to have all incoming and outgoing signals with the same polarity relationship.
Polyphonic WAV
An individual WAV file that contains multiple audio tracks. When recording multi-track audio with polyphonic WAV files all recorded tracks are contained within a single WAV file.
Post-fader routing (after fade routing, AFL)
The signal from a channel is routed to a bus after the fader in the signal path. The fader controls the level of the channel at the bus. Channels sent to a master bus, such as the left/right bus, are typically sent post-fader.
Post-roll
An extra period of time that is appended to the end of a recording when stop is pressed. If record is pressed during this period of time, recording will resume within the same file with no audio lost. This is particularly useful should a Director call ‘cut’ prematurely or accidentally.
Project
An option available for file organization on Sound Devices recorders. Projects are the highest level of file folder organization. The project folder can contain sub-folders of scene files or recorded files directly.
Record bell
A tone generated in headphones to alert the listener that recording has started. The bell is also produced when recording has ended with the stop button, when the recording volume is full, or when power is in a critical state.
Record Folder
The destination folder for recorded takes. The 8-Series supports a three-tier folder hierarchy allowing for flexibility in organizing recordings.
Sampling rate
When converting between analog and PCM digital audio the analog signal is measured (sampled) in unique steps at a data rate specified in kHz. Higher sampling rates allow for representing higher frequency analog audio. 48 kHz is the standard sampling rate for production, worldwide. Higher sampling rates including 96 kHz and 192 kHz are used for high-precision applications where the representation of audio above 20 kHz is required. A general rule is that the maximum analog audio frequency is ½ the sampling rate.
Scene
On Sound Devices recorders the scene becomes part of the file name for a take. Scene names can be pre-loaded to quickly change between scenes.
Slate microphone
A microphone, built-in or external microphone, on an audio mixer used to notate takes or communicate with sound team members by the mixer’s user speaking into the microphone. Slate microphones are often routable to buses or tracks.
Smart Battery
A lithium-ion rechargeable battery with integrated telemetry indicating battery condition, run time and other useful data.
Stereo linking (inputs)
When active for stereo sources such as stereo microphones, linked inputs are hard panned to the left and right bus. Controls including gain (trim), fader, high pass filter, delay, limiter, mute, and routing are controlled together.
Solo
A control on a mixer to route a channel to headphones while muting all others. Solo and PFL are related controls and in many consoles are the same. Solo circuits can be exclusive—only one channel is sent to headphones at a time—or non-exclusive—any number of channels can be sent to the solo circuit and appear in headphones.
SuperSlot™
SuperSlot™ is an electro-mechanical connection protocol, developed by Sound Devices, to simplify the interconnection of wireless audio transmitters and receivers with audio mixers and cameras. SuperSlot provides, power, audio, and control signals over a single multi-pin connection. SuperSlot-compatible products will be offered by multiple manufacturers, including wireless system manufacturers, camera manufacturers, and audio mixer manufacturers.
TA-type connector (TA3, TA4,TA5)
Miniature XLR-type, locking connectors. TA3 connectors are used by Sound Devices for various inputs, outputs, and as balanced and unbalanced connections. TA4 connectors are used by Sound Devices for DC power connections to the 833 mixer-recorder. TA4 is also used for audio connections from lavalier microphones to some wireless transmitters. TA5 connectors are used for the 833 headset input. TA6 connectors are presently not used by Sound Devices though they are used for audio connections by other manufacturers.
Take
A recorded take is an individual recorded file (or files when recording monophonic WAV files) generated by a recorder. Take numbers are auto-incrementing. Take numbers are added to the end of the file name.
Take list
Separate from a file list, a take list consolidates related files such as a group of monophonic WAV files generated by a single take and presents them as a single take.
Test tone
See tone oscillator.
Timecode
A numerical clock value expressed in hours:minutes:seconds:frames, i.e. 04:59:39:05, used to synchronize cameras, video decks, and audio recorders. Timecode requires clocks on devices to be synchronized, either through a wired or wireless connection between devices, or through a process called “jam sync” where each device, which requires a high-precision clock, runs independently after their clocks are synchronized.
Timecode mode
Sound Devices recorders offer multiple timecode modes. Different modes correspond to different timecode workflows. Common modes available in Sound Devices recorders include:
record run - timecode advances only when recording is engaged
free run - timecode run continuously, typically with the start of production being at 0 hour
24 hour - similar to free run except the start time corresponds to time-of-day
ext TC - the recorder applies the value of an external timecode source.
Tone oscillator
A sound generator producing a sine wave tone at a given frequency at a given output level. With its known output level tone oscillators are helpful to set gain structure between audio equipment.
Track
A single recorded audio signal. Common recorded tracks are the main left/right master audio bus and isolated (iso) channel recordings. Iso tracks are typically identified by the channel of the same number, e.g. channel 1 is sent to track 1, channel 2 is sent to track 2, etc.
Track arm
Tracks that are active and ready for recording are said to be “armed”. When recording begins all armed tracks begin recording. Depending on the production is may be advantageous to arm and disarm tracks, especially to disarm unused tracks.
Track name
Individual tracks of a multi-track recording can be named to indicate microphone type or character name.
Trim
Also defined in mixers as “gain”, the trim adjustment is the first stage of gain of a microphone or line level input. Typical microphone trim values range from 10 dB to 50 dB, depending on microphone sensitivity and volume of the sound source.
User bits
Static, numeric data that is available as part of a timecode signal. User bits are often used to indicate the date of a file. User bits are four sets of two-digit hexadecimal numbers from 00 to ff.
WAV File
A universal, well-supported file type for sound file recordings. WAV files can contain one or more (up to 65,535) tracks of PCM audio data at any sampling rate and bit depth. A standard WAV file is limited to a maximum file size of 4 GB. Sound Devices uses the .WAV extension for recorded files, including for files with Broadcast WAV metadata.
WAV RF64
An extension of the WAV file type that supports file sizes larger than 4 GB. When recording high track count, high sampling rate polyphonic WAV files, the 4 GB size limitation of WAV can be reached quickly. RF64 files larger than 4 GB require recording to a volume type than can support file sizes larger than 4 GB.
Word clock
A reference signal used to synchronize the sampling rate of multiple digital devices.
XLR female
Industry-standard 3-pin locking audio connector for microphone and line-level sources. Predominantly used as an input. Also shown as XLR-F.
XLR male
Industry-standard 3-pin locking audio connector for microphone and line-level sources. Predominantly used as an output. Also shown as XLR-M.
