Sound Devices 633 Mixer/Recorder


The Sound Devices 633 Mixer/Record is built from the ground up with production mixing in mind. This 6 input mixer with integrated 10-track recorder is compact, rugged and designed to make sure you never miss a moment of dialogue.

The ability to record simultaneously to both SD and CompactFlash cards coupled with Powersafe circuitry and the ability to power the mixer from up to four power sources with seamless swap-over safeguard your recordings.  A 10-second internal battery and automatic file closure and shutdown on power loss help prevent file corruption and data loss.

The Sound Devices 633’s light weight, conveniently placed ports and faders and long battery life make it an excellent choice for over the shoulder work.
