The 833 is the professional’s tool for mobile and small productions. Like the popular Sound Devices 633, the 833 is small, lightweight, and compact. A tactile interface with dedicated faders, trim knobs, and PFL switches makes this mixer-recorder ideal for run-and-gun bag use.

The 833 has 6 mic/line preamplifiers, 8 channels, 12 tracks, 6 analog outputs, and ultra-accurate timecode. Many features have carried over from the premium Sound Devices’ Scorpio, such as Sound Devices’ new preamplifier design, 2 SD card slots, dual L-Mount battery charging and powering, and an internal 256 GB SSD.

Additionally, the 833 shares the same processing architecture and multiple FPGAs as the Scorpio. This enables the 833 to be fully routable, and any physical input can be routed to any track. The 833 features both digital and analog inputs and outputs, and has multiple powering options, so it will fit effortlessly into your existing kit.

A built-in three band EQ may be set to either pre- or post-fade for each channel to tackle any problems directly on-set. Enable Dugan Automixing or MixAssist to automatically attenuate unused microphones in multi-microphone applications. Up to 8 channels can be automixed at a time. If you are recording in a noisy environment, enable the optional NoiseAssist plugin to suppress common background noises instantly on-location.

Dedicated coms and slate allows for professional bi-directional communication with other crew members. Send customized mixes to the camera or crew with multiple mix buses. With the ability to record to three media simultaneously, you can turn over SD cards to production at the end of the day while keeping a backup on the internal 256 GB SSD.

The 833 may be controlled via the companion Android and iPad app, SD-Remote, which features transport controls, metering, and sound reports. For an instant mobile workstation, choose from one of several supported USB control surfaces for remote fader and transport control. The SL-2 Dual SuperSlot Wireless Module easily mounts to the top panel, providing up to four channels of wireless audio in each slot.

What’s with the name?

Scorpio is the most powerful mixer-recorder we’ve ever created, so we wanted to give it an instantly memorable name. Scorpio is also the 8th sign in the zodiac – perfect for the 8-Series line of mixer-recorders.

The 833 is similar to the tried and true 633 but with substantially more powerful hardware.

The 888 replaces and improves upon the popular 688 and 788T.

How big is it?

The Scorpio is roughly the size of the 688.

The 833 is roughly the size of the 633. The 833 has more depth but is slimmer than the 633.

The 888 is roughly the size of the 788T – just a bit thicker.

What production bags fit my mixer-recorder?

The Scorpio fits nicely in the Sound Devices CS-688 production case. There are also some third-party options available. 

The 888 is roughly the same size as the 788T. There are a number of third-party production bags on the market made for the 788T that should accommodate the 888. 

833 – Bags designed for the 633 may or may not be suitable for the 833. This depends on the size of L-Mount batteries attached. For example, the CS-633 bag will house the 833 but only with 2200 mAH L-Mount batteries. 

We are currently working with third-party manufacturers to develop additional bags for the 8-Series. 

Is the 8-Series difficult to operate?

No – the tactile interface makes it perfect for run-and-gun productions. For users familiar with Sound Devices’ 6-Series, the 8-Series will feel very similar. The menus and physical controls are very much alike. However, due to the much greater capability, there will be some learning curve. Plan to take a couple of hours to familiarize yourself with your 8-Series mixer-recorder before using it in mission critical applications.

What does the antenna connection do?

The antenna is used to connect the 8-Series via Bluetooth LE to SD-Remote, the companion app for Android and iPad.

I lost or broke my antenna, is there a replacement part available?

Yes. You can purchase the XL-ANT2.4 Replacement Antenna for 8-Series from your preferred reseller.

I work outdoors, how does the LCD perform in sunlight?

We carefully selected the LCD based on size and performance – both indoors and out. The transflective LCD is clearly visible in direct sunlight.

I noticed my 8-Series mixer-recorder can get warm when in use, is this normal?

Yes. By design, the chassis gets warm, wicking away the heat from the internal components. The cooling of internal components is important for long-term reliability; this is accomplished via our electro-mechanical design which uses high-thermal-conductivity aluminum and direct heat-sinking of critical internal components.

The 8-Series’ quiet mic preamps and powerful processing engines are state-of-the-art, and this level of mixing/recording power in a compact chassis leads to a bit of heat being generated.

Best practices for keeping your mixer-recorder as cool as possible include powering down unused channels when not in use, leaving at least ½” of air space around it when used within a bag, and by opening rear/side flaps of the bag to allow air to flow.


What are my options for powering my 8-Series mixer-recorder?

Scorpio can be powered from several sources, including two DC inputs (TA4 connectors) or two L-Mount batteries. If the SL-6 is in use, the SL-6 4-pin Hirose DC input or NP-1 battery powers the entire system.

The 888 and 833 can be powered via the DC input on a TA4 connector or two L-Mount batteries. 

All power sources operate in series, allowing for long run times.

Can my 8-Series mixer-recorder charge the L-Mount batteries?

Yes. There are two built-in chargers, one for each battery. These can be turned off via the menu.

Why did you choose to use the TA4 for power instead of the 4-pin Hirose on other SD products?

All 8-Series mixer-recorders can draw a significant amount of peak current: the battery chargers can draw over 3 A alone, and 4-pin Hirose connectors are only rated for 2 A per pin. The TA4 connector provides up to 5 A per pin and allows the use of smart batteries. 

How should I wire the TA4 to connect to a standard battery?

For standard, only use pins 1 and 4 for connection.

What smart batteries can I use?

You can use smart batteries from AudioRoot, Inspired Energy, etc. We have our own labeled smart battery called the XL-SmartBattery.

Can I use Hawk-Woods data batteries like the NP-98D?

Yes. The Hawk-Woods NP-98D data batteries communicate battery telemetry to the 8-Series when connected via the Hawk-Woods NPD-TA4 shoe.
Please note that the current Sound Devices XL-NPTA4 does not support data communications.



What battery information can be read/displayed from smart/data batteries?

When a smart or data battery is in use, the battery’s time remaining and percent remaining are displayed on the meter screens. In the Power menu, you can also view the battery’s cycle count and temperature.

Can I use a smart/data battery to power the SL-6 with Scorpio?
You can power the SL-6 with Scorpio using a smart or data battery but no battery telemetry will be displayed on the Scorpio interface. The SL-6 hardware does not support the data lines needed to read this information.  


How is routing different from the 688 or 788T?

Unlike the 688 and 788T, all 8-Series mixer-recorders have a full I/O matrix and multiple mix buses. Each physical input can be routed to any combination of buses, tracks, and outputs. 

See Scorpio Block Diagram

See 833 Block Diagram

See 888 Block Diagram

Can I send channels at different levels to multiple buses?

Yes. All channels feed the Left and Right mix bus post-fader. Additional buses can be fed from any channel, pre-fade or post-fade, or with a unique bus send level.

What are my options for each channel?

On Scorpio, channels 1-32 can be fed from analog mic or line, AES3 or AES42 (XLR inputs 1 and 6), USB 1 or 2, Dante, optional SL-2 accessory, optional SL-6 accessory, optional XL-AES accessory, or Rtn-A, -B, or -C. Channels 1-16 are fully featured with trim, delay, polarity, high-pass filters, 3-band EQ, pre-and post-fade compressors, stereo or MS linking, and pre- and post-fade limiting. Channels 17-32 include trim, high-pass filters, pre-and post-fade compressors, and limiters.

On the 888, channels 1-16 can be fed from analog mic or line, AES3 or AES42 (XLR input 1), USB 1 or 2, Dante, optional SL-2 accessory, optional XL-AES accessory, or Rtn-A or -B. All channels are fully featured with trim, delay, polarity, high-pass filters, 3-band EQ, pre-and post-fade compressors, stereo or MS linking, and pre- and post-fade limiting.

On the 833, 8 channels can be fed from any of the six analog mic or line inputs, AES3 or AES42 (XLR inputs 1), USB 1 or 2, optional SL-2 accessory, optional XL-AES accessory, or the Return (Rtn). All channels are fully featured with trim, delay, polarity, high-pass filters, 3-band EQ, pre-and post-fade compressors, stereo or MS linking, and pre- and post-fade limiting.

How do I control channels that don’t have front panel access?

Each channel has an associated Channel screen from which you can setup any channel parameter. Trims, faders and bus sends for Channels 13-32 (Scorpio), channels 9-16 (888) and channels 7-8 (833) are controlled through their channel screens which may be accessed via the Menu or by using the star toggle switches + PFL toggle.  For physical fader and trim control of these additional channels, a supported USB control surface may also be used.

Do all microphone preamplifiers support 48 V phantom power?

Yes, and phantom provides a full 10 mA per channel.

Can I adjust the levels of incoming Dante audio?  

Yes. On the Scorpio and 888, Dante audio routed to channels can be controlled with trim (pre-fade gain) and faders.

Can I use my 833, 888, or Scorpio as an audio interface to my computer?

Yes, the 833, 888, and Scorpio all support two channels in and out over USB-C. The mixer-recorder will show up as a USB audio device using the computer’s class compliant drivers. Mac supports up to 24-bit, 192 kHz, and Windows 10 supports up to 24-bit, 96 kHz. 

Additionally, via Dante, the 888 acts as a 16 channel in and out audio interface, and the Scorpio acts as a 32 channel in and out audio interface. 

Can I link multiple 888s or Scorpios together?

Yes, two 888s or Scorpios can be linked via audio through Dante.  On Scorpio, all 32 ISO tracks, plus 4 buses, can be recorded on the second Scorpio to three storage media simultaneously. On the 888, send up to 16 channels of Dante to another 888 or a Scorpio. All recorded tracks then appear on one unit and one set of media.

How do I properly wire the TA5 Headset?

When wiring up a headset with the TA5 connector, it is important that the balance microphone signals are wired to shielded twisted pair *separate from the headphone signals*. Keep in mind that there can be >80 dB of amplification between the mic and the headset and just a bit of bleed between the mic signal and headphone signal can lead to oscillation.

You can also buy a premade headset, such as these options from Remote Audio.

My setup requires more AES inputs, how can I use more AES sources?

Check out the optional accessory XL-AES: 8 Channel AES3 Input Expander for 8-Series for connecting AES3 sources. If you are looking to send AES audio from wireless slot-in receivers, you can simplify your setup using the SL-2 Dual SuperSlot Wireless Module.

Does the XL-AES come with an extension cable? Will you offer one?

The XL-AES is designed to connect directly to the top panel expansion port of any 8-Series mixer-recorder. An extension cable is not available or supported. 

Does the XL-AES rotate or can it be positioned another way than with the connectors facing the rear of the 8-Series mixer-recorder?

The XL-AES needs to be connected and mounted with the TA3 connectors facing the rear of the unit. 

Does the XL-AES add 8 extra channels and tracks to the 833, 888, or Scorpio?

The XL-AES provides additional AES3 inputs to feed the existing channels and tracks of the mixer-recorder. If you need extra channels you should consider the 888 or Scorpio. 

When the XL-AES is attached, where can I put my receivers?

The XL-AES was designed to have a very small footprint. The overall height of the 8-Series Mixer-Recorder only increases by .75-inches (19 mm) when the XL-AES is attached leaving plenty of room in the bag for other devices. 

Are the XL-AES inputs sample rate converted?

Yes all eight channels of the XL-AES are sample rate converted to the 8-Series clock source. This alleviates any concern of clocking issues with multiple digital input sources.


How many tracks can I record at the various sampling rates?

Scorpio – 36 tracks at sample rates 96 kHz and below, and up to 18 tracks at 192 kHz.

888 – 20 tracks at sample rates 96 kHz and below, and up to 18 tracks at 192 kHz.

833 – All 12 tracks can be recorded at 192 kHz.

Can I arm or disarm tracks during recording?

Yes. When a track is armed or disarmed during recording, a new file is created, including the added track, or excluding the disarmed track, respectively. The two files will be sample-continuous. This feature is great for reality show productions or any production where recording never stops.

It appears that most recorders have a maximum file size of 4 GB? What if I want to record long events without the files splitting at 4 GB?

The 8-Series supports the exFAT file system and RF64 WAV (64-bit) files. This allows file sizes up to 16 EB (ExaBytes – 260). In other words, you can fill up the entire 256 GB internal SSD with a single file with no splits.

Can the 8-Series record compressed audio files like MP3, AAC, etc, for transcription purposes?

The Scorpio, 888, and 833 allow real-time recording of a two-track, timecode-stamped AAC file from LR or B1B2.

Why AAC and not MP3?

AAC and MP3 are both lossy digital compression audio formats. AAC (Advanced Audio Coding) files achieve better sound quality than MP3 at a given file size.

I see 32-bit A/D Converters listed in the specs. Is that the same thing as a 32-bit float bit depth?

The A/D converters used on the Scorpio, 888, and 833 are 32-bit resolution parts, but this is unrelated to 32-bit float files. The ability to record in 32-bit float is a future possibility.

Why does the track count exceed the channel count?

All 8-Series mixer-recorders have four mix buses (L, R, B1, B2). The number of available recorded tracks equals the amount of isolated channels plus the four mix buses.

Does the 833 have Dante? 

The 833 was designed to be a lightweight, portable bag companion. Dante is particularly useful for larger scale cart-based productions with considerably more I/O. If Dante is needed in your workflow, please consider the 888 or Scorpio. 


Is there internal storage?

Yes. All 8-Series mixer-recorders have an internal 256 GB SSD.

In addition to the internal SSD, your 8-Series mixer-recorder can record to two SD cards, which may be easily delivered to post.

Can this SSD be replaced by a user?

Any user modifications, including drive replacement, nullify the warranty. We highly recommend having Sound Devices Service replace the drive. Replacement drives will be available as a service part in the future.

What SD cards are recommended?

The current list of approved SD cards can be found on 8-Series Approved Media page.

Why won’t the SD card slide easily into the slot?

Cards must be inserted label-side down.

My Read/write speeds from my computer to the SSD and SD cards is slower than I anticipated?

Make sure the USB-C cable in use is USB3. USB2 cables do not have all the needed conductors and will greatly reduce transfer speeds.

Can I record to an external drive or USB storage device? 

The Scorpio, 888, and 833 can record to the internal SSD, SD 1, and SD 2 simultaneously. USB Storage devices are not supported.

Can I use my XL-DVDRAM?

No. 2006 called, they want this question back.

How about Mini DVD-RAM, Orb, or Jaz drive?


I noticed when I format the SSD and SD cards I’m not seeing the full capacity advertised.

We over-provision (reserve free space on) the media for optimum performance.


Does my 8-Series mixer-recorder have an on-board Dugan Automixer? 

Yes. It is always a pleasure working with our friend Dan Dugan. Dugan Automixing was and is a well loved feature of the 633 and 688 and there was no way we would leave it out of the 8-Series. Automixing attenuation of each isolated channel is vividly displayed on the front panel LCD and Ring LEDs. 

The Scorpio and 888 allow automixing of channels 1-16; the 833 allows automixing of channels 1-8.

Does my 8-Series mixer-recorder support MixAssist?

Yes. MixAssist intelligently attenuates unused microphones to reduce unwanted artifacts in multi-microphone applications, and as of v3.00 has joined Dugan Automixing as an available algorithm on the 8-Series. The ring LEDs and LCD show when a channel is fully open or being attenuated. The off-attenuation of unused microphones can be set from 6 to 40 dB.

MixAssist is processed on the LR Bus. The Scorpio and 888 allow up to 16 channels of MixAssist automixing and the 833 allows up to 8 channels. 

Which automixer should I use – MixAssist or Dugan Automixer?

Both Dugan Automix and MixAssist accomplish very similar goals: they turn down the microphones not actively in use, and they maintain the overall system gain between microphones to 0dB. Read Automatic Mixing 101 to learn about the differences between the two automixers.


Where can I learn more about NoiseAssist?

Can I use my CL-1, CL-2, CL-6, CL-8, or CL-9?

The Scorpio, 888, and 833 are built with an entirely new architecture which does not support these products.

Will my 8-Series mixer-recorder work with the Sound Devices CL-12 Linear Fader Controller?

Yes. CL-12 support was added in v3.00. The CL-12 connects to the 8-Series Mixer-Recorder with a USB-A to USB-A cable. 

Will you make a dedicated control surface designed specifically for the 8-Series?

Yes. The CL-16 Linear Fader Control Surface for 888 and Scorpio is now available. A follow-up firmware release will add support for the 833. Learn more about the CL-16 here.

Can I control my 8-Series mixer-recorder from a USB Control Surface with linear faders?

Yes. Sound Devices supports open protocols wherever possible. The Scorpio, 833, and 888 support the ubiquitous MCU (Mackie Control Universal) protocol which many USB-connected control surfaces use. Currently the following USB control surfaces are supported:

  • Behringer X-TOUCH

  • iCON Platform X+
  • iCON Platform B+
  • Mackie MCU Pro
  • Sonosax SX-LC8+
  • Sound Devices CL-12
  • Sound Devices CL-16

Can I use the CL-12 with one of the supported third-party MCU controllers?

No. The CL-12 must be the only controller.

Can I program my own controller? 

We conform to the MCU protocol, however Sound Devices cannot guarantee proper operation with anything other than the supported controllers listed above. While you are free to make your own controller, we cannot offer any technical support.

Is there a mobile device remote application?

Yes. The SD-Remote companion application for Android and iPad is available. The Scorpio, 888, and 833 can connect via USB or Bluetooth LE to Android tablets, and via Bluetooth LE to iPads. USB provides robust data interconnect and device charging with a single cable.
The app offers a large display for up to 16 channels of metering and timecode, scene, take and note editing, track arming, soloing, muting, trim and fader level control, transport control, and more. The app conveniently allows you to manage and create sound reports and email a CSV and/or PDF.

What are the minimum requirements to run the SD-Remote app?

SD-Remote requires an iPad running iOS 13+, Android 6 Marshmallow for USB connection to an Android tablet, or Android 7 Nougat when connecting via Bluetooth LE.

Does the SD-Remote app support Samsung DeX?

SD-Remote does not support DeX. It is recommended to disable DeX when using SD-Remote.

My 8-Series mixer-recorder won’t connect via USB to SD-Remote on my Android tablet. Is there a workaround?  

Some tablet data connections perform better when the USB current is limited to 500 mA. Try setting Menu>System>USB Charge Out to 500 mA.

You can also try connecting via Bluetooth LE. Go to the Settings tab (touch the gear icon) to change your connection method. After selecting Bluetooth, return to the main screen and touch the SD icon. Then, choose the device you wish to connect.

Does the app connect over Bluetooth?

Yes. Starting with v3.20, SD-Remote for Android allows either a USB or Bluetooth LE connection. SD-Remote for iPad functions solely over Bluetooth LE.

Why does SD-Remote for iPad only connect via Bluetooth LE when Android SD-Remote connects via Bluetooth LE or USB? 

Android tablets allow serial communication over USB without any special authentication hardware. If having a hard-wired connection to SD-Remote is important to you, consider using an Android tablet with your 8-Series Mixer-Recorder.

Can I use Sound Devices Wingman?

Wingman is for 6-Series and MixPre only.

Can I use a USB Keyboard, SD-Remote, and a Control Surface at the same time?

USB hubs are supported on the USB-A connector. This means that you can connect to a hub with multiple supported USB devices and use them simultaneously. This allows you to run SD-Remote, a USB Keyboard, a supported USB Controller, USB lights, etc… We have not tested USB Hamster wheels, USB exercising dogs, USB warming gloves, or any other such devices.


What SuperSlot accessories are available for the 8-Series?

The SL-2 Dual SuperSlot Wireless Module, designed for 8-Series mixer-recorders, is available now! Read about the SL-2 here.

Scorpio will also accommodate the SL-6 Power and Wireless System originally designed for the Sound Devices 688.

Does Scorpio support the SL-6?

Yes. Using the SL-Riser, the SL-6 can be fixed to the top panel of Scorpio and the six available wireless receiver outputs may be routed to channels 1-16. Scorpio supports SuperSlot. The following third-party SuperSlot-ready receivers are supported via the SL-6: 

  • Audio Ltd A10-RX
  • Lectrosonics SRb (with audio board update from Lectrosonics)
  • Lectrosonics SRc
  • Lectrosonics SRc-941
  • Lectrosonics SRb5P and SRc5P (Slot B or C only)
  • Sennheiser EK-6042 (does not support scan)
  • Wisycom MCR42 (with SLK42-IKSS rear panel adapter from Wisycom)
  • Wisycom MCR54 (only 2 audio channels per slot supported)

Do the 833/888 support the SL-6?

No. Only the Scorpio supports the SL-6.

Can I run an RF scan of a SuperSlot receiver from Scorpio?

Yes, RF Scan is available on the Audio Limited, Lectrosonics, and Wisycom receivers.

Will the Scorpio UI support the RF Scan of the Sennheiser EK-6042?

No. The Sennheiser EK-6042 does not provide the Scorpio with a way to trigger or display the results of the scan. Sennheiser recommends doing all scan functions from the EK-6042.

Why do I need the SL-Riser with the SL-6?

Mechanically, the SL-Riser positions the receivers seated in the SL-6 further back so that the receivers don’t overhang Scorpio’s front panel. The SL-Riser is not needed for the SL-2.

Why should I upgrade?

I own a 633, why should I consider the 833?

The 833 has several advantages to the 633, including:

  • 3 additional microphone preamplifiers
  • 2 additional channels
  • 256 GB Internal SSD
  • 3 recordable media
  • 12 Record tracks
  • Dedicated trim and fader controls for channels 1-6
  • Flexible routing 
  • Recordable Return
  • Dual L-Mount battery charging
  • 3-band EQ on every channel
  • Compressors on every channel
  • Word Clock In and Out
  • Powerful processing architecture with multiple FPGAs
  • Supports multiple third-party USB control surfaces
  • Advanced transport and level controls via companion app SD-Remote
  • Post-roll
  • Track arming during recording
  • Track to media routing
  • TA5 headset port
  • Bus Sends
  • Tunable Timecode
  • High speed USB file transfer
  • Wireless integration via the optional SL-2 accessory
  • Access to the NoiseAssist Plugin
