The Sound Devices 833 is the location sound professional’s tool for mobile and small productions alike. Like the popular Sound Devices 633, the 833 is small, lightweight, and compact, while housing the latest technological advancements in mic pres, routing and recording capabilities. 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.
