Sound Devices 833 Portable Mixer-Recorder

Built for bag work and smaller productions, the Sound Devices 833 is a portable mixer-recorder with six mic preamps, eight channels, and 12 tracks.

Dedicated faders, trim knobs, and PFL switches give it a hands-on interface for run-and-gun work. The optional +4 Plugin adds four fully featured ISO channels and record tracks, taking it to 12 channels and 16 tracks.

Routing and Processing

The 833 shares the Sound Devices Scorpio’s processing architecture and multiple FPGAs, so any physical input can be routed to any track. Each channel has a three-band EQ that sits pre- or post-fader. Dugan Automixing or MixAssist handles up to eight channels, and the optional NoiseAssist and Cedar sdnx plugins suppress background noise on location. Dedicated com and slate controls handle talkback, and its buses send custom mixes to cameras and crew.

Recording

It records to its internal 256 GB SSD and two SD cards at once, so you can turn over SD cards at the end of the day and keep a backup on the SSD. Choose 16-bit, 24-bit, or 32-bit float at sample rates up to 192 kHz, and record AAC files for transcription.

Power and Control

Two rear L-mount battery slots charge and power the 833, and its locking TA4 input takes 10 to 18 V. The SD-Remote app for Android and iPad gives transport controls, metering, and sound reports, and supported USB control surfaces add faders for a mobile cart.

The SL-2 Dual SuperSlot Wireless Module mounts to the top panel with up to four channels of wireless audio in each slot. An Astral ARX16 docked with an A20-QuickDock adds 16 channels of wireless with no cables.
