Should the unit be on all the time?

Are there any internal fuses?

Questions And Answers

Owner’s Reference GCC Power Amplifier Series

The GCC Control Amplifi er is best left powered on at all times. The current draw is negligible and keeping it powered on will make sure the internal AC capacitors stay working properly.

There is no harm in leaving the unit on at all times as the lifespan of the GCC Control Amplifi er will be unaffected by leaving it on. We recommend placing the amplifi er in its standby mode via the front panel logo/standby button when the amp is not in use. We further recommend leaving power to the GCC Control Amplifi er at all times.

There are no user replaceable internal fuses inside the GCC Control Amplifi er. There is an internal fuse that should only be replaced by an authorized service center if needed. The components inside the GCC Control Amplifi er have lethal voltages when powered and even when un-powered. Capacitors inside the GCC Control Amplifi er can retain an electrical charge after the unit has been powered down. Do not attempt to get inside the unit for any reason unless instructed to do so by your dealer or an authorized service representative. Should the GCC Control Amplifi er cease to function, contact your dealer or PS Audio’s service center for help.

Placement?	Placement of the GCC Control Amplifi er is not critical. Placement with respect to other equipment
	can be important. In general, place the GCC Control Amplifi er as close to the source equipment
	as possible. It is always preferable to have long speaker cables and short interconnects if there is
	a distance problem. Long interconnect cables will degrade the performance of most preamplifi ers,
	surround processors or integrated amplifi ers and receiver preamp outputs. The outputs on
Isolation?	Isolation through the use of spikes, cones or Sorbothane feet is recommended for the GCC Control
	Amplifi er if space and budget allows. Isolation of any piece of high-end stereo and theater equipment
	is always recommended wherever practical.

Front panel blue light

The brightness of the blue light on the front of the GCC Control Amplifi er can be adjusted via the rear panel three position switch. The switch is located on the upper left hand corner of the GCC Control Amplifi er as you face the rear panel. When the switch is in the upper most position, the front panel light will be the brightest. The middle position of the switch provides medium brightness, the lower position shuts the light off.

Front panel power button

The front panel PS logo is the power button. Press the blue PS logo on the GCC Control Amplifi er’s front panel to turn the amplifi er on or off. We recommend keeping the rear mounted switch for the blue light brightness at one of the two visible levels so you can tell if the GCC Control Amplifi er is on or off.

Do cables make a difference?

What speakers can I use?

Yes, cables make a difference. It is important to use the best power cables, interconnects and speaker cables when operating the GCC Control Amplifi er.

You can power nearly every loudspeaker made with a GCC Control Amplifi er. It is relatively tolerant of most loudspeakers loads and will not be damaged by attempting to power heavy loads. If, while playing music, the GCC Control Amplifi er continues to go into a protection mode when the music gets loud, it means that the speaker load is probably too diffi cult for the GCC Control Amplifi er and the next
