Overview
The 833 serves as the go-to tool for professionals engaged in mobile and small-scale productions. Similar to the popular Sound Devices 633, it boasts a compact, lightweight design suited for on-the-go use. Its tactile interface, complete with dedicated faders, trim knobs, and PFL switches, caters to run-and-gun bag setups.
Equipped with 6 mic/line preamplifiers, 8 channels, 12 tracks, 6 analog outputs, and ultra-precise timecode, the 833 ensures top-notch performance. Many features inherited from Sound Devices’ premium Scorpio, including the new preamplifier design, 2 SD card slots, dual L-Mount battery charging and powering, and an internal 256 GB SSD, further enhance its capabilities.
