The Sound Devices 833 is a lightweight and compact production mixer-recorder designed for over-the-shoulder and other portable applications. It features eight input channels - three via XLR, three via TA3, and the final two through the 1/8" input return.

The 833 offers six full-featured microphone preamplifiers,12 tracks of recording, six analog outputs, and an ultra-accurate time code generator. Features from the Scorpio recorder are also incorporated, including a new preamplifier design, dual SD card slots, internal 256 GB SSD storage, dual L-Mount powering and charging, and Dugan Automixing with up to eight channels in two separate groups mixed simultaneously.

Additionally, the 833 shares the same powerful processing and FPGA architecture as the Scorpio for complex signal routing, control, and signal processing. Any physical input can be routed to any track and the built-in three band EQ per input channel can be applied either pre- or post-fade. The 833 features both digital and analog inputs and outputs, has multiple powering options, and is compatible with the Icon Platform M+ Control Surface.

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 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.
