A built-in internal AM/FM tuner with RDS (Radio Data System) support is optional as source one. An RNET(R) link using CAT-5e allows for metadata transmission and control of Russound RNET Smart Source components, including the SMS3 Smart Media Server, iBridge(R) Dock and Bay, and ST2 Tuners with AM/FM and/or satellite radio.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.
