The CM16a MultiSignal Processor is a key hardware component of QSControl, QSC's Ethernet based audio network. The CM16a provides sixteen channels of gain control, monitoring, and amplifier management for DataPort-equipped QSC amplifiers. The CM16a is operated remotely by a Pentium-based PC or QSC System Controller running QSControl application software. Control and monitoring data is communicated between the Pentium-based PC or QSC System Controller and CM16a via an Ethernet network. The CM16a, located in the amplifier rack, is linked to each amplifier via a DataPort.
