Troubleshooting

Owner’s Reference GCP Stereo Preampliﬁ er

If you have a problem connecting a subwoofer, please refer to the quick start guide in the front of this

manual. We do not recommend connecting the high level inputs of a self powered subwoofer to the

outputs of the GCC Series Power Ampliﬁ er for some subwoofers. For many subwoofers it will be ﬁ ne.

Some, like the REL subwoofers and the Carver and Sunﬁ re type of subwoofers, may not work properly

when connected to the GCC Series Power Ampliﬁ er’s outputs. This is because the GCC Series Power

Ampliﬁ er is a balanced type of output with a DC voltage as referenced to ground.

If the GCC Power Ampliﬁ er shuts off when playing music, there are several possibilities. If the music

plays quite loudly but shuts off on the most explosive parts of the music or video soundtrack, then the

GCC Power Ampliﬁ er is probably underrated for the type of speaker you are using. See your dealer or

call PS Audio for advice on going to the next size GCC Series Power Ampliﬁ er in the series.

If the ampliﬁ er shuts down with very little volume, then check the speaker cable connections. The

GCC Power Ampliﬁ er is so powerful that it can actually play music at low levels even into a near short

on its outputs. Chances are good that you have a shorted connector (plus touching the minus) and

you should simply check carefully on the back of the speaker and the back of the ampliﬁ er.

If you can’t dim the front panel display, it’s probably because you are not using the remote control.

The only way to dim the front panel display is to press the Dim button on the remote. As soon as you

change volume or inputs, the display will automatically brighten and then dim back to its preset level.

If you need to dim the blue light on the front panel below the display, there is a switch located on the

rear of the GCC that has three brightness settings.
