The chairman unit not only provides the same function as the delegate unit, but also supports the addition of a “Priority button”
The CS-120DU is the basic delegate unit. Under the control of CS-120CU there are 4 types of operation mode.
Both are flush mount design. All funcitons are the same as CS-120DUE and CS-120CHE but with
more competitive prices.
Main unit of the whole system. It provides all inputs and outputs needed to manage complex audio system.
