The 833 has 6 mic/line preamplifiers, 8 channels, 12 tracks, 6 analog outputs, and ultra-accurate timecode.

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 to automatically attenuate unused microphones in multi-microphone applications. Up to 8 channels can be automixed at a time, and two separate groups can be mixed simultaneously.

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.

    Sound Devices 833
    Le 833 est parfait pour des tournages documentaires où le nombre de participants peut augmenter sans pré avis. Très facile d'ajouter des personnes. Le 48v sur 6 entrées permet d'éviter le poids supplémentaire d'une mixette. Ça fonctionne bien avec le StingRay Junior, pas eu besoin de changer de sac. Read more
