Sound Devices 833

Properties:

The 833 is a mobile audio mixer and recorder with 8 channels, 6 busses, 12 tracks, 6 analog outputs and 6 quiet and reworked preamps. A high-precision timecode can also be used. The audio mixer is equipped with XLR, TA3 and Aux connectors, through which it can receive numerous different audio signals. Dugan Automixing is available for automatic mixing for 8 channels. The mixed audio signals are recorded either on the internal 256 GB SSD or on two SD cards. The 833 is powered either by the TA4 input or two Sony L-series batteries.
