QSControl Amplifier Network Monitor
The CM16a Amplifier Network Monitor is a key hardware component of QSControl, QSC’s
Ethernet-based audio network. Each CM16a provides sixteen channels of audio level control,
monitoring, and amplifier management for DataPort-equipped QSC amplifiers. The CM16a is
operated remotely by a Windows-based PC functioning as the System Controller running
QSControl application software. Control and monitor data is communicated between the System
Controller and CM16a over an Ethernet network. The CM16a, located in the amplifier rack, is linked
to amplifiers via DataPort cables. The CM16a also serves as the network interface for QSC’s digital
signal processors, including the DSP-3.
