QSC Audio Network Audio Systems User Manual
QSControl (pronounced Q’s Control) is a powerful
and flexible system that provides remote
management and diagnostics of QSC amplifiers
and other audio devices over an Ethernet
network—including selected QSC DSP devices,
such as the DSP-3 digital signal processor. You
can monitor and control hundreds of amplifiers
simultaneously, as well as perform a wide range
of advanced functions, including event logging,
real-time monitoring of loudspeaker opens and
shorts, plus configuration of the DSP-3 module.
A QSControl system is composed of a System
Controller (a Microsoft Windows-based PC)
running QSControl Software that is linked via
Ethernet to CM16a Amplifier Network Monitors or
other networked audio devices. Each CM16a
provides sixteen channels of remote level
adjustment and amplifier management for
DataPort-equipped QSC amplifiers.
Key Components of QSControl
CM16a Amplifier Network Monitor
The CM16a Amplifier Network Monitor offers powerful amplifier
management in a QSControl networked audio system, using Ethernet
technology to communicate with the host system controller. The System
Controller uses application software to operate the networked
audio system, including the CM16a units and their amplifiers .
Each CM16a performs monitoring and control functions for QSC DataPortequipped amplifiers using DataPort cables . Further, the CM16a connects
to QSC’s family of digital signal processors such as the DSP-3.
Control Application Software
There are two ways to run QSControl applications on the System Controller.
The first is with System Manager, QSC’s standard application included with
the QSControl system, requiring no user programming. The second is to
create a custom application using the QSControl Development Tools in
Microsoft Visual Basic. Using these tools, the system can be customized to
your specifications.
System Controller
QSControl Software runs on a computer configured with select Microsoft
operating systems—including Windows® 2000. The Graphical User Interface
(GUI) program controls QSC’s and third-party networking products.

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.
