Problems with subwoofers

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 amp shuts down while playing music

If you cannot dim the display

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.
