The CS-120CH has extra functions besides those CS-120DU has. There is a priority key which can either mute or turn off all delegate units, or cancel all applying.
The control unit is the center of the discussion system which controls the microphones of the chairman and delegate units as well as connects to other audio input and output.
The chairman unit not only provides the same function as the delegate unit, but also supports the addition of a “Priority button”
The CS-120EXU Power Supply Unit is designed to provide extra power when the total number of delegate and chairman unit exceeds 90 in a installation.
