Master Control Unit    is the central management device of the system, which is used to manage
and monitor all devices and performvarious operations. MCU is integrated with audio storage, broadcast,
zone control, monitor, timing control, fault diagnosis, etc. functions. Built-in 500W digital power amplifier
can drive maximum 8 loudspeaker lines to meet requirements for small applications. It can also be connected
to zone expanders to increase system capacity for the requirements of large applications as well.
