Accurate timecode synchronization and numerous powering options make the 833 adept at handling the varied demands of modern productions. For enhanced operating convenience, you can control the 833 wirelessly via the SD-Remote Android app or from a compatible USB-connected MIDI controller.

Simultaneous 12-Track Recording
Record all eight input channels and four buses at the same time in samples rates up to 192 kHz, and even arm or disarm tracks during recording. The 833 utilizes monophonic and polyphonic BWF (Broadcast WAV) files that support embedded timecode and extensive metadata such as track names, file names, and notes. For quick entry of metadata text, you can hook up a USB keyboard.
Multiple Buses with Flexible Routing
In addition to the main stereo bus, the 833 boasts four independent buses for flexible creation of custom mixes. All buses feature configurable source and destination routing as well as linkable limiters. Assign any physical input to any channel, send any channel to any bus, and even virtually "patch" sources (physical inputs or internal buses) to physical outputs.
32-Bit A/D Converters
Built with precision 32-bit A/D converters, the 833 ensures audio recordings surpass those of off-the-shelf, IC-based mic preamps. Plus, the vast dynamic range of the 32-bit converters allows you to record at extremely high or low levels without causing distortion or undue noise.
Records to Three Media
The 833 features an internal 256GB SSD and dual SD card slots. Customizable track-to-media routing means that you can record redundantly to all media or select specific sources for each media.
8-Channel Dugan Automixing
Enable Dugan Automixing to automatically attenuate unused microphones in multi-microphone applications. Up to eight channels can be automixed at a time, and two separate groups can be mixed simultaneously.
Six Mic/Line Preamps with Independent Phantom Power
Passed on from the flagship Scorpio, the 833's Class-A preamps deliver premium amplification with a massive 76 dB of maximum gain and an ultralow noise level of -131 dBV (-129 dBu). Six locking inputs (three XLR and three TA3) with per-channel 12V/48V phantom power support mic level and +4 dBu line level to accommodate external microphones or balanced outputs from high-end wireless receivers. The first XLR input can alternatively accept AES3 or AES42 digital signal.

Independently switchable polarity, multistage limiting, 3-band EQ (pre- or post-fade), and low-cut filtering allow you to tailor each channel for the best tone. Plus, six channel fader knobs and six channel trims with LED rings ensure fast mixing on the fly.
3.5mm Aux Input
A single 3.5mm mini jack serves multiple input functions. Use it as an additional channel input or to monitor the audio return from a camera or DSLR.
Versatile Analog and Digital Outputs
The XLR main outputs can function as analog or digital outputs. Assign them to send stereo analog signal at line, -10 dB, or mic level, or set them to route up to four channels of AES3 digital signals. Two X1/X2 TA3 jacks are presented for additional line, -10 dB, or mic-level balanced outputs, and a single X3/X4 3.5mm mini jack is nearby for an assignable unbalanced output.
Headphone and Headset Jacks
The 833 features 1/4" and 3.5mm stereo headphone outputs and a TA5 headset port, all driven by 400mW per side for high output and compatibility with headphones of any impedance. Selectable and editable headphone presets empower you with fast configuration of the monitoring source, mono/stereo/MS mode, and more. With the addition of the dedicated TA3 com return jack, the 833 is capable of coms and slate for professional bidirectional communication with other crew members.
Powerful FPGA Processing
The FPGA-based engine boasts a 6-way ARM multiprocessor system that executes 64-bit audio processing precision, letting you have total control of each track's sonic characteristics in real time.
Powered via L-Series Batteries or External DC
The 833 supports powering from dual L-Series batteries and external DC power (10 to 18 VDC) via a locking TA4 connector. Intelligent power-down of unused mic preamps and select internal circuits minimizes unnecessary power drain. The 833 has on/off switchable built-in chargers for convenient charging of your L-Series batteries.
Accurate Timecode Synchronization
The 833's LEMO jack supports 2-pin and 5-pin options for functionality as an input or output for timecode or word clock. Sync to the internal clock, word clock, LTC in, or AES, and choose from multiple timecode modes such as free run, auto record, jam sync, and many more. The precision timecode generator's start time and UBits may be specified by the user. The 833 will hold timecode for up to four hours after shutdown.
Ideal for Sound Bag or Camera-Mount Configurations
Sized like the popular 633 mixer, the rugged, compact, and lightweight 833 is compatible with common setups. With all audio and power connections on the side panels, it fits handily in sound bags. Female 1/4"-20 threads on the bottom panel supports tripod- or camera-mounted arrangements.
Powerful Wireless/Wired External Remote Control
Control the 833 remotely from a USB-connected Android device via the SD-Remote app, which generates sound reports and displays high-resolution meters, current timecode, transport buttons, solo/mute buttons, and more.

For tactile mixing and transport control, connect a compatible USB MIDI controller such as the Icon Platform M+/X+/B+, the Behringer X-Touch, or the Mackie MCU Pro.
Firmware v8.10 Supports GainForward Architecture for 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 either directly at the mixer’s trim control or at the wireless receiver.
  • When the A10-RX receiving an A20-Mini signal is slotted into an SL-2 or SL-6, the A10-RX Input menu settings are bypassed and all gain, low cut, and limiter activity are performed and controlled by the 833, 888, or Scorpio. Trim gain range is 0 to 60 dB for the 8-Series channel receiving signal from the A20-Mini.
  • A10-RX Receiver Setup screens show limiter, high-pass filter, and clipping status of the associated 8-Series channel when receiving signal from the A20-Mini.
  • Jam A20-Mini timecode from 8-Series using a standard USB Type-A to USB Type-C cable from Menu > Timecode/Sync > Jam A20-Mini.
  • New SuperSlot menu option “Use Transmitter Names” automatically applies the A10-TX and A20-Mini transmitter names to the associated 8-Series Track Name.

what does 32-Bit (A/D Conversion) mean on the ...

what does 32-Bit (A/D Conversion) mean on the spec list, does it mean If I want to record 32-bit, I will need to connect it to computer?
Asked by: ali
The 32-bit specification refers to the amount of audio information the Sound Devices 833 8-Channel / 12-Track Multitrack Field Recorder is capable of capturing while recording in reference to bit depth. 32-bit recording captures more information mainly due to its floating-point format versus traditional fixed-point bit depths of 16 and 24 bit. This, in essence, allows for a much wider dynamic range to be captured and makes it hard to record clipped or distorted signals. Sound Devices publishes a useful article on their site that explains this in depth and can be found here: https://bit.ly/3SGcsE5

What does it mean when all of the channel LED rings are flashing yellow, and it won't allow me to record?
Asked by: shaun
Regarding the Sound Devices 833 8-Channel / 12-Track Multitrack Field Recorder, when all of the channel LED rings are flashing yellow and won't allow you to record, that means your sync reference is set to "external", but there is no external source. You would just need to set your sync reference to "internal".
