Powering the MixPre II

Apply your choice of power source. Turn the master power switch located in the upper right corner of the left side panel to the On

position. To ensure the battery/power status indicator displayed on the touchscreen shows accurate level and status, select your battery/ power type in the Power menu.

When using AA batteries to power the MixPre II, we recommend Energizer Ultimate Lithium (not alkaline batteries). The high internal resistance of alkaline batteries makes them only suited to devices requiring low current (less than 25 mA), not higher power electronic devices such as the MixPre II.

Incorrect use of batteries poses a danger of explosion. Replace only with the same or equivalent type. Properly recycle batteries. Do not crush, disassemble, incinerate, dispose in a fire or expose batteries to high temperatures.

Save power by turning off unused channels.

With multiple options for powering, your MixPre II can operate in a wide array of applications and environments.

MixPre-3 II and MixPre-6 II Power Options

1. Included MX-PSU AC wall adapter to USB-C power supply.

2. Four AA batteries installed in the included MX-4AA Battery Sled.

3. Eight AA batteries installed in the optional MX-8AA Battery Sled accessory.

4. One or two Sony-type L-Mount batteries installed in the optional MX-LMount battery sled accessory.

5. USB-C to USB-C cable (included) connected to a USB-C host computer or AC wall adapter.

6. USB-A to USB-C cable connected to a USB-A host computer or AC wall adapter. The unit will enter a low power state and some functionality will be limited with this power option.

7. MX-USBY Dual USB-A to USB-C optional accessory cable connected to a USB-A host computer. Use this cable option if your computer is unable to provide adequate power with only one USB-A port.

MixPre-10 II Power Options

1. Included XL-WPH3 AC to DC 12 V Power supply with 4-pin Hirose.

Power Switchover and Priority

MixPre-3 II and MixPre-6 II

To preserve battery power, USB-C power sources take priority over batteries if both are connected with one exception - if the USB-C power source does not meet the full power requirements of the MixPre II, you can choose to power from battery or continue to power from USB-C. An underpowered MixPre II will be able to use two of the three or four channels with 48 V phantom mics. Other channels can still be used with dynamic mics and line level, Aux, or USB sources. In a low power state, the MixPre II automatically:

1. Dims LCD and LED Brightness.

2. Disables USB-A port.

3. Disables HDMI TC port.

For protection against accidental loss of power, the MixPre II incorporates circuitry to automatically switch over from USB-C to batteries.

MixPre-10 II

For preservation of battery power, 4-pin Hirose power sources take priority over batteries if both are connected. For protection against accidental loss of power, the MixPre-10 II incorporates circuitry to automatically switch power sources.

Channel Screen - Basic Mode

The MixPre II’s flexibility is enhanced by its ability to select various input types to its mixer channels. On the MixPre-3 II, channels can be sourced from XLR mic/line input, 3.5 mm Aux line or mic input, or from USB channels. On the MixPre-6 II and MixPre-10 II, channels can be sourced from XLR or TRS mic/line input, 3.5 mm Aux line or mic input, or from USB channels.

Access the channel’s input settings by pushing in the channel’s knob. There are 3 channel inputs on the MixPre-3 II,  5 channel inputs on the MixPre-3 II with +2ch plugin, 6 channel inputs on the MixPre-6 II, and 10 channel inputs on the MixPre-10 II.

Settings for extra channels 4-5 on the MixPre-3 II with +2ch plugin, ch 5-6 on MixPre-6 II, and ch 9-10 on the MixPre-10 II are accessed from the Inputs menu. Input source, gain, pan, and low cut are all available in this menu.

Tip: To quickly access these extra channels’ input settings without having to go via the Inputs menu, simultaneously press HP knob and the Ch 1 or Ch 2 knobs.

Channels use a single gain stage adjusted by the knob. Levels set at the channel knob are sent to the LR mix record channels and the LR outputs. Limiters are present on each channel and the LR mix bus and will ensure that your audio is safe from accidental clipping.

Pan

Pan the channel’s signal Left, Center or Right in the stereo LR mix and Stereo Out.

Low Cut

Turn Low Cut filter on or off. Useful for reducing unwanted low frequency in the audio of the select channel. In Basic Mode Low Cut

is fixed at 80 Hz. Low Cut is not available for USB input sources.

Input

Select one of the available Mic, Line, Aux (available when Aux In Mode is Mic or Line) or USB inputs as the channel source.

Phantom

Turn on 48 V phantom power when using a condenser microphone in the selected channel (available when Input is Mic).

Channel Screen - Advanced Mode

The MixPre II’s flexibility is enhanced by its ability to select various input types to its mixer channels. On the MixPre-3 II, channels can be sourced from XLR mic/line input, 3.5 mm Aux line or mic input, or from USB channels. On the MixPre-6 II and MixPre-10 II, channels can be sourced from XLR or TRS mic/line input, 3.5 mm Aux line or mic input, or from USB channels.

Access the channel’s input settings by pushing in the channel’s knob. There are 3 channel inputs on the MixPre-3 II,  5 channel inputs on the MixPre-3 II with +2ch plugin, 6 channel inputs on the MixPre-6 II, and 10 channel inputs on the MixPre-10 II.

Settings for extra channels 4-5 on the MixPre-3 II with +2ch plugin, ch 5-6 on MixPre-6 II, and ch 9-10 on the MixPre-10 II are accessed from the Inputs menu. Input source, solo, mute, arm, gain, pan, low cut, and linking* are all available in this menu.

Tip: To quickly access these extra channels’ input settings without having to go via the Inputs menu, simultaneously press HP knob and the Ch 1 or Ch 2 knobs.

*Note: The MixPre-3 (I or II series) with +2ch plugin does not support linking for channels 4 and 5.

Channels use a dual gain stage. Adjust the gain control in the Channel Screen and fader level with the knob. Limiters are present on each channel and the LR mix bus and will ensure that your audio is safe from accidental clipping.

Solo

Lets you “solo” the selected channel in the headphone output. Solo mode can be set to “Individual” or “Multiple” in the HP menu. When a channel is soloed, the LED ring will flash orange.

Mute

Provides quick access to muting an input.

Arm

Allows pre-fade recording of the channel to an individual track on the SD card.

Gain

Sets the sensitivity of the input. Generally, the Gain should be set so that the loudest parts of the audio signal just touch the red segments of the meters. The control knobs on the front panel act as faders.

Pan

Lets you position the audio of the channel anywhere between Left and Right in the stereo image of the LR mix and Stereo Out.

Low Cut

Turn Low Cut filter on or off. Useful for reducing unwanted low frequency in the audio of the select channel. Frequency is adjustable

from 40, 80, 100, 120, or 160 Hz. Low Cut is not available for USB input sources.

Input

Select one of the available Mic, Line, Aux In 1, Aux In 2 (available when Aux In Mode is Mic or Line) or any USB input as the channel source.

Phantom

Turn on 48 V phantom power when using a condenser microphone in the selected channel (available when Input is Mic)

Phase

Phase inversion (or polarity reversal) is used to compensate for incorrectly wired, balanced cables, to prevent signal cancellation when a source is dual-mic’d from opposite directions, or to reverse left/right with microphones in a mid-side (MS) configuration.

Delay

Input delay may be used to compensate for ‘phasey’ sounding audio because of time-of-arrival differences between sound sources, such as a boom mic and wireless radio mic picking up the same sound source.

NOISEASSIST (Requires Plugin)

Sets the amount of noise suppression applied to a channel. Adjust from 0 dB (no suppression) to -20 dB (maximum suppression) in 1 dB steps. Only available when the channel is selected in the System > NoiseAssist menu.

Linking

Odd-even channel pairs can be linked as a stereo pair or mid side pair.

Linking Channels

Are you working with a stereo source—a keyboard or stereo mic perhaps? To make it easier to adjust these types of sources, the MixPre II offers linking of channel pairs (1-2, 3-4 …) either as a stereo pair or mid-side (MS) pair.

Note: The MixPre-3 (with or without +2ch plugin) offers only linking of channels 1-2.

Stereo Pair Linking

Control the level of both the first and second channels with the first (odd-numbered) Channel knob. The second (even-numbered) Channel knob functions as a balance control.

MS Pair Linking

Control the level of both the first and second channels with the first (odd-numbered) Channel knob. The second (even-numbered) Channel knob functions as a width control. You can choose to have the MS decoder apply to the mix only or both ISOs and mix in the menu Inputs > MS Decode.

Multichannel Linking

When multiple channels are linked, gain, fader, limiters, track arming, low cut filters, and input delay are all linked and controlled from the first Channel. Additionally, the Link Type menu provides the options for which parameters are linked.

All links input type, trim gains, faders, limiters, low cuts, record arms, and delays

Faders Only links only fader level.

The MixPre-6 II can link channels 1-3 and 1-4.

The MixPre-10 II can additionally link channels 1-3, 1-4, 1-5, 1-6, 1-7 and 1-8.

Gain Staging with Linking

You can use linking with single gain stage or two-gain stage (trim/fader) operation. For instance, users wanting to link inputs 1-2 or 1-4, but control all levels from the front-panel Channel 1 knob should set System > Mode to Custom and then in Custom Setup, set Gain to Basic and Channel to Advanced.

Users wanting to link those same inputs but use two gain stages should use Advanced Mode or Custom mode with both Gain and Channel set to Advanced. Then, you can adjust trim gain levels for linked channels from the Channel 1 screen and adjust fader levels for linked channels with the Channel 1 knob.

Inputs Menu

The Inputs menu allows you to access software-controlled channel screens (4-5 on MixPre-3 II with optional +2ch plugin, 5-6 on MixPre-6 II or 9-10 on MixPre-10 II), Aux In Mode settings, MS Decode settings, Knob Press options, Ambisonics (MixPre-6 II and MixPre-10 II only with optional Plugin), and MixAssist (with optional Plugin).

Software-Controlled Channel Screens

Channel screens for channels 4 and 5 on MixPre-3 II with optional +2ch plugin, channels 5 and 6 on MixPre-6 II, or channels 9 and 10 on MixPre-10 II provide access to a channel’s settings and functions. This includes input source, solo, mute, arm tracks, gain, pan, low cut, linking*, and NoiseAssist attenuation (when NoiseAssist plugin is installed and routed to the channel via System>NoiseAssist menu).

*Note: The MixPre-3 (I or II series) with +2ch plugin does not support linking for channels 4 and 5.

Configures how the Aux/Mic In 3.5 mm connector is used.

• Mic: Select this option when the Aux/Mic In is to be used with a mic. The MixPre II provides bias voltage for PiP (plug-in-power) mics. Aux 1 and 2 are available as input sources to any channel.
• Line: Select this option when the Aux/Mic In is to be used with an unbalanced 2ch line source, such as smartphone headphone output, stereo line source, etc. Aux 1 and 2 are available as input sources to any channel.
• Camera: Select this option when the Aux/Mic In is to be used for monitoring a video camera’s audio output via the MixPre II’s headphones and camera return (C1/C2) meters located on meter view.

• This is particularly useful when you want to use the MixPre II to drastically improve the sound quality recorded on the camera. It is common knowledge that camera mic inputs are not of high quality so by connecting your mics to the MixPre II instead, then connecting the MixPre II’s L/R outputs to your camera audio input, you will achieve far superior sound quality. Then by connecting the camera’s audio output to the MixPre II’s Aux/Mic In, it allows you to check that the camera audio is noise and distortion-free.
• When this option is selected an additional setting appears in the Input Menu called Camera Gain. This lets you adjust the gain of the incoming camera audio level. You also get additional camera monitoring options in the HP Presets menu.
• When Aux In Mode is set to Camera, you cannot route Aux In to a channel and thus you cannot record it.

• Timecode (Aux In 1 or 2): Select this option when using an external timecode source connected to the Aux/Mic In port. The 3.5 mm TRS connector is wired to receive timecode on its tip for Aux 1 or ring for Aux 2.

• Set Menu > Timecode > TC Mode to Aux In 1 or Aux In 2 accordingly.
• When Aux In Mode is set to Timecode Aux in 1, Aux In 1 audio is disabled and cannot be selected as a channel’s audio input source. However, Aux In 2 can still be selected as an audio input source*

When Aux In Mode is set to Timecode Aux in 2, Aux In 2 audio is disabled and cannot be selected as a channel’s audio input source. However, Aux In 1 can still be selected as an audio input source*

* Setting one Aux In to timecode automatically sets the gain range of the other Aux In to Line.

• Off: Select this option to turn off the Aux/Mic Input.

MS Decode

Applies to all channel pairs that are set to MS Linked. Choose between ISOs & Mix (decodes MS source to stereo on the ISOs and the mix) and Mix Only (decodes MS to stereo into the mix only and leaves the ISOs as undecoded MS).

Knob Press

Selects the behavior of  pressing a Channel Knob. Available in Advanced Mode.

1. Ch.View: Pressing the channel knob enters the channel view. Channel Gain is automatically selected upon entry.  

2. Ch.View + Solo: Pressing the channel knob enters the channel view and automatically solos the channel. Channel Gain is automatically selected upon entry.

Setting Knob Press to Ch.View + Solo does not permit multiple HP Soloing. HP Solo mode is automatically set to ‘Individual’ if it was previously set to ‘Multiple.’

AMBISONICS

MixPre-6 II and MixPre-10 II only. Requires plugin; see separate Ambisonics guide for more information.

MIXASSIST

NOISEASSIST

Requires plugin. NoiseAssist is not available in Music or Ambisonics mode. See separate NoiseAssist guide for more information.

Metering

There are five basic methods for observing input and output levels on the MixPre II.

Channel Knob Ring LEDS

The brightness of the light ring indicates the level of the input. Green = signal present, red = signal peaking, orange = signal limiting. A channel’s ring LED will flash orange when in solo and glow red when the channel is muted. With MixAssist active, the ring LED will show solid green to indicate that the channel is active.

Channel Screen Meter

The Channel screen displays the isolated channel meter in the top left-hand corner.

Home Screen Meters

To switch meter views, touch the meters to cycle through the three different views. The meters show signal levels, current arm status of each track, limiter activity, MixAssist active channel status, and NoiseAssist suppression amount.

Meter Ballistics

Audio meter ballistics is the manner in which a visual meter responds to audio signal levels. Peak-reading ballistics correspond to actual signal peaks, but do not necessarily correspond to perceived signal loudness. Peak meters have an instant attack and slow decay and are useful in digital audio workflows where signal overload can cause immediate distortion. Volume Units (VU) meter ballistics correspond closely to how the human ear perceives loudness. VU meters provide good visual indication of how loud a signal will be, but provides poor information of actual signal peaks.

The MixPre II uses a combination Peak+VU ballistics for all meters, where the perceived loudness (or VU) is simultaneously displayed as a standard bar while the peak signal is displayed as a single, independent segment above the VU.

The built-in tone generator can be used to feed external devices to assist with gain staging. It’s level can be adjusted from -20 to 0 dBFS. Two Tone Modes are available; Continuous or L-Ident, the latter being useful for identifying the left channel of a stereo signal.

MixPre-3 and MixPre-6 II: Tone is routed to the L and R tracks and Stereo Out.  Tone is activated from the Tone menu.

MixPre-10 II: Tone can be routed to any combination of tracks and outputs. Tone is activated from theTone/Slate menu.

Slate Mic (MixPre-10 only)

The built-in slate mic can be used for slating or for coms. It’s level can be adjusted from 0 to 50 dB. Activate from the Tone/Slate menu or using the shortcut * or ** switch (when set accordingly - see Using Star Shortcuts). The slate mic can be routed to any combination of tracks and outputs.

Note: When the slate mic is turned on, Aux In 2 is temporarily disabled because it shares the same audio hardware path as the Slate Mic. When Slate Mic is then turned off, Aux In 2 is re-enabled automatically.

Using the MixPre II as a USB Audio Interface

The MixPre II Series perform as highly capable and pristine quality USB audio interfaces. They support up to 96 kHz sample rate at

bit depths of 16, 24, 32-bit integer or 32-bit float. The MixPre II’s 32-bit float USB audio path makes it possible to record into a DAW above 0 dBFS without clipping.

A list of compatible 32-bit float OS and DAW’s can be found at www.sounddevices.com/32-bit-float-applications

For PC users, the MixPre II appears as a 2x2 audio interface unless a specific ASIO® driver is installed. The latest ASIO drivers are

available for free at www.sounddevices.com/download

A PC running Windows 10 or higher is required to stream 32-bit float audio. A PC running Windows 7 or below will not stream audio at 32-bit float. Please install the correct ASIO driver relative to your operating system.

To work with the USB audio from a host computer, it is necessary to route the USB 1 - 4 sources appropriately. To mix the USB audio from the host computer with live audio from the inputs to the LR bus, use the channel screen and select input source. To hear the USB host computer audio in the headphones only, switch the HP preset to USB 1,2 or USB 3,4.  

The MixPre II is capable of recording and streaming audio to a USB host simultaneously, or recording the USB audio stream out of a computer directly to its SD recorder.

When connected to a computer as a USB Audio Interface the sample rate of the MixPre II is determined by the computer.

Low-Latency Monitoring

Latency has been minimized while using the MixPre-II as a USB interface. In situations where the throughput latency is higher than desired, the input can be directly monitored in the headphone output.

To Monitor With Zero-Latency:

1. Connect via USB-C to the USB port on your computer.
2. Confirm that the LR Stereo HP Preset is selected.
3. Select USB 1 for Channel 1 source (MixPre-3 II), Channel 5 source (MixPre-6 II), or Channel 9 source (MixPre-10 II) and Pan L.
4. Select USB 2 for Channel 2 source (MixPre-3 II), Channel 6 source (MixPre-6 II), or Channel 10 source (MixPre-10 II) and Pan R.

OR

1. Create a custom HP preset that mixes the microphone or input you want to record from with the USB 1 and/or USB 2 feed from the computer. For example, HP L = Ch1 + U1 and HP R = Ch1 + U2.
2. Connect microphone or other inputs to remaining channels.
3. Select USB 1 for Channel 1 source (MixPre-3 II), Channel 5 source (MixPre-6 II), or Channel 9 source (MixPre-10 II) and
4. Pan L.
5. Select USB 2 for Channel 2 source (MixPre-3 II), Channel 6 source (MixPre-6 II), or Channel 10 source (MixPre-10 II) and Pan R.
6. Connect microphone or other inputs to remaining channels.
7. Select the appropriate inputs for remaining channels.
8. Setup your DAW software for a new track with its source being any of the available channels.
9. Disable record monitoring or mute the channel’s output in the DAW.

You should now be able to hear and adjust the output of your DAW audio through the channels you set to USB 1 and 2 on your MixPre while adjusting your low-latency feed in your headphones (and send levels to DAW) using the remaining channel knobs.

USB Output Routing

Each of the MixPre’s USB audio output streams can be sourced from any channel (pre- or post-fade), LR mix bus, headphone output or LR output and X1,X2 (on the MixPre-10 II only).

Mix-Minus Sends

A mix-minus send is used when working with remote contributors in podcasting, conferencing and broadcast applications.  It allows the remote contributor to hear the program mix, minus their own voice, the remove distracting latency.

To Setup Up A Mix-Minus Send:

1. In the Outputs>St.Out Left or St.Out Right menus (or L, R, X1, or X2 Output menus on the MixPre-10 II), create a summed mix of all the channels you want to send to the remote contributor minus their own channel. You can mix the channels pre-fade or post-fade.

2. Select the Output you have configured in step 1 as the source for the USB channel you are sending to the remote contributor.

Formatting Media

SD cards must be formatted by the MixPre II for reliable recording and playback. Back-up any wanted audio recordings or data on the SD card before formatting. The formatting process erases all data on the SD card.

If a USB thumbdrive is inserted into the USB A port, the MixPre II automatically copies the current project’s recorded files to it. The thumbdrive must also be formatted before use.

We highly recommend using Sound Devices branded SD cards as these have been optimized to provide the best performance. If these are not available, most reputable manufacturers’ cards (such as SanDisk or Delkin) that meet or exceed class 10 speeds are acceptable. Similarly, we highly recommend only using Sound Devices’ approved USB thumbdrives to ensure reliable operation.

Current approved media can be found here.

All media will be formatted as exFAT. If any media is formatted differently, the MixPre will display a formatting reminder. The exFAT file system is not compatible with Windows XP or Mac OS X 10.6.4 and lower.

Format SD Card

1. Insert an SD card in the slot located on the rear panel.
2. Navigate to SD Card > Edit > Format.
3. When asked to confirm the command to format the card, touch OK.
   

Format USB Thumbdrive

1. Connect a USB ThumbDrive to the USB-A port located on the left panel or USB hub.
2. Navigate to USB Drive > Edit > Format.
3. Confirm the command to format the card, and touch OK.

USB Auto-Copy

The MixPre II will auto-copy to a formatted USB-A thumbdrive when inserted directly into the USB-A port or when using a USB hub. Stopping a recording will automatically copy the last recorded file to the thumbdrive. While copying, the record button on the MixPre-3 II and MixPre-6 II and the ring LED on the MixPre-10 II will flash while the process is being completed. The completion rate will display as a percentage on the bottom right corner of the status bar. If a new recording is started while auto-copying is still in progress, auto-copying will still continue.

Interrupting USB Auto Copy With Power Cycle

Auto-copy can be temporarily suspended during longer copying times.

During auto-copy in stop mode, pressing stop or toggling the power switch to OFF brings up the following popup:

“Suspend USB auto-copy? Copying will resume when record is next pressed. OK, Cancel”

If “OK” is pressed, Auto-copying is suspended and will resume copying when record is next pressed.

If “Cancel” is pressed, Auto-copying will continue until complete then power down if switch is off or sit in idle if power switch is on.

While the MixPre II is auto-copying, the USB Drive and SD Card menu are unavailable.

Record Bells

Enable or disable record bell notifications. Record bells are On by default.

File Splits

To conform to the Broadcast WAV File standard ,the maximum size of a file recorded by the MixPre II is 4GB. If a recording exceeds this limit, the MixPre II will automatically begin recording a new file. The recording process is seamless, meaning the two files can be joined together in post with no loss in audio.  

Timecode

When timecode is enabled, it is displayed on the home screen beneath the current filename. Standard timecode is displayed as HH:MM:SS:FF. Drop-frame timecode is displayed with a semicolon between the seconds and frames fields: HH:MM:SS;FF.

Each time you press record, the current timecode value is stored inside the Broadcast WAV file. Most popular video editing applications can read this timecode value to help sync the audio with picture.

When power is removed, the internal battery maintains accurate timecode for up to 4 hours. An alert will be issued whenever the timecode generator (in Free Run and Time of Day timecode modes) has reset due to internal battery depletion. This internal battery is automatically charged anytime the MixPre II is powered on.

TC Mode

Select between Free Run, Time of Day, Rec Run, BNC In (MixPre-10 II only), Aux In 1, Aux In 2, HDMI TC In, HDMI FUJIFILM or Off. When using Aux In 1 or 2 for Timecode, be sure to set Inputs>Aux In Mode to Timecode.

Set UBITS

Click “Mode” at top to edit UBits Mode. From the main screen, press in with the headphone encoder to modify the value of a UBit. Use the arrows or scroll with the encoder to select.

To maintain accurate timecode count over a power cycle, ensure MixPre is not connected as a USB audio interface to a computer during power up. It is best practice to rejam timecode devices after switching modes (Basic, Advanced or Custom) or after any setting change requiring a reboot (32-bit float, MixAssist, Music mode or Ambisonics).

Timecode Modes

Free Run

Timecode runs continuously. Timecode continues counting accurately for up to four hours after power-down.

REC Run

Timecode runs while recording and is stationary when not recording. In this mode, timecode defaults to the last stationary value at power-up. When switching to Record Run from another mode, the internal generator will stop at the last timecode value. Timecode output can be used to trigger other equipment that supports timecode remote triggering to start and stop recording.

Time Of Day (TOD)

Alternatively known as 24 hr run mode, this is similar to free run mode except that the timecode generator is automatically loaded with the time of day. Use TOD mode when you want the recorded WAV files to be timecode stamped with the time of day generated by the internal clock.

BNC In, AUX In 1, AUX In 2

Timecode can be derived from external timecode connected to the TC In BNC or to the tip or ring of the 3.5 mm Aux/Mic In connector.

HDMI TC In

Many DSLR-style cameras output timecode via HDMI.

If HDMI TC In is selected without an HDMI source connected, the MixPre II will report missing sync. The MixPre II has two HDMI timecode modes,. HDMI flag for Sony, Panasonic, Nikon, Canon and Blackmagic cameras and HDMI FUJIFILM for FUJIFILM cameras.

LTC Timecode is not present on the MixPre-3 II and MixPre-6 II

Stereo Out or the MixPre-10 II BNC out when HDMI TC In is in use.

When set to HDMI TC In, the connected camera determines the sample rate of the MixPre II.

OFF

Setting TC Mode to Off disables the timecode feature. When Off, the time counter below the filename region on the home screen displays elapsed time instead of timecode.

Presets

Arming/Disarming Tracks

1. Tap the meter label. When armed the label turns red. When on but disarmed, the label is gray. When the input is off, the label is black and cannot be armed.  
2. Meter labels are joined (displayed as a single label) to indicate when channels are linked.

ENABLE BLUETOOTH ON THE MIXPRE

This toggles Bluetooth On and Off. If a remote password is configured on the recorder in the System>Wingman Password menu, Wingman will prompt for that password to be entered prior to making the connection.

Set And Clear The Wingman Password

For added security, set up the MixPre recorder to require a password for remote access. Use the virtual keyboard or a USB keyboard to enter a password up to 18 alpha-numeric characters . Punctuation other than a hyphen or an underscore is not permitted.

File List Tab

MixPre files and their embedded BWF/iXML metadata can be viewed and edited in the File List tab.

Sound Report

Sound reports can be created and sent direct from Wingman as CSV files.

USB Hub

The MixPre II supports multiple USB devices such as USB thumb drives, Midi controllers, and/or USB Keyboards via a USB hub.

To maximize USB hub support, note:

Powered hubs are recommended as these can deliver appropriate current.

If using non-powered hubs, do not connect more than three low power devices.

Connect each USB device individually rather than all at once.

The peak current of all three devices at once may exceed the max peak current of the supply.

If devices are randomly dismounting there is not enough current to power all the attached devices. Remove one or more devices or use a powered hub.

USB-A support (with or without hub) is only available when MixPre is fully powered and not in low power mode.

Only one USB controller can be used at a time.

Only one USB drive can be used at a time.

When using non-powered hubs with the MixPre 3 II or 6 II, use an L-mount battery, a 4-pin Hirose DC adapter (e.g. from Hawkwoods), a USB-C wall adapter, or USB-C battery pack (e.g. from Anker or Ravpower). USB-C from a computer may not provide sufficient power to operate all USB devices connected to a non-powered USB hub.

The USB-A port does not support hubs when being powered from AA batteries.

Use a high quality USB-C to C cable when powering from a USB-C power source, preferably one meter or less. Low quality USB-C cables  could cause erratic behavior.

USB Keyboard

A connected USB keyboard may be used as a wired remote control for certain functions. Holding a keyboard function for longer than 0.5 seconds will repeat the shortcut action.

X-Keys® Programmable Keypads, Sticks & Keyboards

X-Keys include a variety of compact, tactile input devices that can be programmed to emulate USB keyboard commands. Their various buttons and tactile controls are programmed via P.I. Engineering’s MacroWorks Windows software. When mapped as individual commands or as macro commands to MixPre’s USB Keyboard shortcuts listed above, they offer quick-access to many MixPre functions including Record, Stop, Play, and many more.

To use with MixPre, the X-Keys device must be connected to the MixPre’s USB-A port.

Please visit P.I. Engineering’s website for more information.

USB Controllers

The MixPre II Series can be connected to select third party controllers for tactile control of mixing and recording. These control surfaces provide a varied range of physical sliders, pots, and buttons to set fader levels, trim gains, pans, reverb sends, solos, mutes, record arming, transport control and more. Functionality varies depending on controller model. When connected to the MixPre II, some functions are taken over by the controller and are therefore disabled on the MixPre II.

Compatible Recorders

1. Korg NanoKontrol Studio
2. Korg NanoKontrol 2
3. Novation LaunchControl XL
4. AKAI MidiMix

Connecting The Mixpre To A Controller

Power and control is provided via a single USB cable to better facilitate simple connection between the MixPre and controller. For the MixPre-3 II and -6 II, USB Controllers will only function if the MixPre is adequately powered.

1. The MixPre may be powered on before USB connection or may be turned on after USB connection.
2. Connect one end of a USB cable to the MixPre’s USB-A port and the other end to the controller’s USB port, which can be a USB-B, Micro USB, or Mini USB port, depending on the controller model. We recommend using the USB cable supplied with the controller.
3. A popup screen displays the controller model. After a few seconds of configuration, the popup closes and the controller is ready to use.

Mounting to a Camera or Tripod

All MixPre II Series recorders have ¼-inch, 20-threaded screw mounts on their top and bottom panels for mounting to gear.

To attach your MixPre II between a camera and tripod:

1. Remove the battery sled to gain access to the back panel.
2. Retrieve the anti-rotation pin and Allen wrench. Both are
3. magnetically held in place in the back panel.
4. From the MixPre II’s bottom panel, insert the Allen wrench into the mounting screw hole and push up to reveal the retractable screw. Rotate
5. to screw the MixPre II into place underneath the camera.
6. Align the mounting screw hole on the bottom panel of the MixPre II with the screw on the tripod plate. Rotate the screw on the tripod plate until the MixPre II is affixed.

If your camera has a slot for the anti-rotation pin, screw the pin into place on top of the MixPre II, and then position the MixPre II against the bottom of the camera so that the pin fits into the camera’s slot. The anti-rotation pin may also be screwed into a tripod and slotted into the bottom of the MixPre II.

Users who register their product directly with Sound Devices Technical Support using the online form or by phone, will receive an additional ONE (1) year of warranty coverage, extending the complete warranty period to TWO (2) years from the date of original retail purchase. In order to extend the warranty coverage period, registration must be completed within the initial ONE (1) year warranty period. Products must be purchased through authorized Sound Devices resellers to qualify for Warranty coverage. Damage resulting from the opening of a Sound Devices product or attempted repairs by a non-authorized Sound Devices repair technician will void warranty coverage.

This is a non-transferable warranty that extends only to the original purchaser. Sound Devices, LLC will repair or replace the product at its discretion at no charge. Warranty claims due to severe service conditions will be addressed on an individual basis.

THE WARRANTY AND REMEDIES SET FORTH ABOVE ARE EXCLUSIVE. SOUND DEVICES, LLC DISCLAIMS ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. SOUND DEVICES, LLC IS NOT RESPONSIBLE FOR SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES ARISING FROM ANY BREACH OF WARRANTY OR UNDER ANY OTHER LEGAL THEORY. Because some jurisdictions do not permit the exclusion or limitations set forth above, they may not apply in all cases.

Product returned without an RMA number may experience delays in repair.
