Sound Devices 833

Fully routable. Ultra-portable. 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. Upgrade with the +4 Plugin to add four fully-featured ISO channels/record tracks, increasing the 833 to 12 channels & 16 tracks. 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 or CEDAR sdnx plugins 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.

Expand this to 16-channels of wireless audio with the A20-Nexus. Connection via the top panel with an A20-QuickDock provides totally cable-free solution for all power, audio and GainForward.

Elevate your kit with the 833 Portable Compact Mixer-Recorder.

The 833 ships with the XL-WPTA4, XL-ANT2.4, and includes 1 XL-LCD-PROTECT protective cover.
