The MCA-C5 Multizone Controller Amplifier provides eight zones of distributed stereo audio from any of eight sources. The source loop outputs and the addition of up to five additional controllers allow for scalability to 48 zones. A variety of input options have been engineered into the MCA-C5 controller. A built-in internal AM/FM tuner with RDS (Radio Data System) support is optional as source one. An RNET link using CAT-5e allows for metadata transmission and control of Russound RNET Smart Source components, including the SMS3 Smart Media Server, iBridge Dock and Bay, and ST2 Tuners with AM/FM and/or satellite radio. Custom audio settings, Party Mode, Do Not Disturb, source and zone linking, and All On/Off participation are standard features. Incorporated in the MCA-C5 is a system clock with an alarms and sleep timers, Home Theater trigger, routed and common IR outputs, and eight 12VDC trigger outputs. Source eight can serve as a paging input and loop output for connection to a third party paging or phone system. The MCA-C5 features digital amplifiers providing 40 watts of power per channel to zones one through six. All zones are equipped with fixed or variable line-level outputs for outboard amplification or subzone use. The MCA-C5 has a front USB port for programming ease and a rear RS-232 port for integration with home automation systems. With MDK-C5 Multiline Display Keypad or Russound UNO-TS2 touchscreens, the MCA-C5 communicates from its built-in tuner and other Russound Smart sources vital information such as preset name, AM/FM station frequency, satellite radio station ID, artist, and song title.
