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.
