DCS 420

The audio monitor unit is a 2 RU unit offering acoustic control and visual level metering of audio in the PROMATRIX® system. The DCS 420 system control functions are carried out through a connection to the DCS 401/401R control module. When using remote amplifiers, switching audio signals to the monitor bus is accomplished directly inside the amplifier. With several external sound sources connected, switching is performed through the DCS 409/409R module. The signals are transmitted via remote interconnection cables. An additional cover panel on the left side can be equipped arbitrarily with controllers, switches, keys and so on. The module has CE marking as well as UL and CSA recognition.
