Owner’s Reference GCC Power Amplifi er Series
higher wattage model should be considered.
The GCC Control Amplifi er is specifi c to your country’s voltage. Do not use the GCC Control Amplifi er
on a voltage higher than it is rated for. For instance, do not take a 120 volt rated GCC Control Amplifi er
and attempt to use it in a 230 volt country. Failure to observe this cautionary note will void your
warranty and may damage the amplifi er. If you need to operate the GCC Control Amplifi er at a voltage
other than the voltage it was designed for, contact your dealer, distributor or the factory.
If the GCC Control Amplifi er protection circuitry is activated, the amplifi er will immediately shut off and
the fault will be indicated on the front panel display. Check for the source of the problem, then use the
front panel logo switch to restart the amp.
The GCC Control Amplifi er produces little heat under normal operation. There are vent holes at the
rear of the chassis, both top and bottom and you should be careful not to obstruct these vents if
possible.
The GCC Control Amplifi er can remotely activate another piece of equipment, such as a second power
amplifi er, by a DC control voltage. Using a small mini jack, you can use the GCC Control Amplifi er to
turn on and off another piece of equipment with a 12 volt trigger. When connected to a GCA Control
Amplifi er trigger input jack, located on the lower left hand corner of the GCA amplifi er’s rear panel (as
you face the panel), the GCC Control Amplifi er will now turn the second amplifi er on and off with a
push of the GCC’s front panel power button.
To dim the front panel display, you must use the remote control. On the control is a dim button.
