The S-4000R is a component of the S-4000 Digital Snake System. It allows for zipperless remote control of preamp levels for an S-4000S-3208 or any other system source configuration up to 40 channels. It can also switch Phantom Power and Pad settings for individual channels. The remote controller can store 9 presets including all of the channel gain and other settings. This allows for fast changes from act to act in a festival and an easy way to return to defaults in an installation.
