IQ-MC Modules
4 Operation
With the IQ-MC option, your CTs
4200 and CTs 8200 amplifiers can
be monitored and controlled from a
remote location through the use of
an IQ System. This module features
SmartAmp™ capabilities which will
enable the amplifier to function au-
tomatically. For example, the IQ-MC
module can automatically limit the
audio signal, also detect and report
various problems.
In addition, the IQ-MC Load Su-
pervision feature has the ability to
verify the status of the loads in real
time.
The IQ-MC module uses Crown’s
IQ2 protocol. This makes it possible
for a user to design custom graphic
display modules to control and moni-
tor the unit with IQ2-compatible IQ
software. This allows even greater
flexibility within Crown’s IQ software
via custom control pages. Plus, the
IQ2 protocol provides for third-party
programming for system controllers
such as those from AMX and
Crestron.
The following sections describe the
IQ-MC features and operation.
Where specified, some features are
accessed via controls located on
the unit itself. However, many of the
features can be controlled or con-
figured using IQ for Windows soft-
ware. Commands are transmitted
via an IQ interface to the specified
IQ component (an IQ2-compatible
interface is required). Please con-
tact your Crown representative or
Crown’s Technical Support Group if
you are unfamiliar with IQ software.
4.1 Hardware
4.1.1 Data Signal Presence
Indicator
An amber Data Signal Presence Indi-
cator (DATA) is provided on the IQ-
MC connector panel as well as the
front of the amplifier. It flashes when-
ever commands addressed to the IQ-
MC module are received. To assist
with troubleshooting, an option that
forces the DATA indicator to remain lit
is available through IQ software.
4.1.2 Preset Indicator
A green PRESET indicator is provided
on the IQ-MC connector panel. This
indicator signals the number of the
currently selected preset by emitting
a series of flashes which match the
preset number, followed by a pause.
The indicator will continuously repeat
the number selected until a change is
made to any setting.
4.1.3 IQ Bus Input Connector
An RJ-45 connector provides the
input connection to the IQ Bus. Drop-
out relays maintain loop integrity in
the event power is removed from the
IQ-MC module.
4.1.4 IQ Bus Daisy Output
Connector
An RJ-45 connector is provided for
normal daisy wiring output to the next
device on the loop in the IQ Bus.
4.1.5 AUX Input/Output and
Listen Bus Connector
An RJ-11 connector provides three
functions. The AUX output delivers
15 VDC at 70 mA maximum output
when switched on and may be con-
