Owner’s Reference GCP Stereo Preamplifier
No sound comes out of the amp
Check the input
Try another source
If you suspect an output problem
If there is a lot of hiss in your speaker
If no sound comes out of the GCC Control Amplifi er there are several areas to check:
•You are not getting an audio signal into the Control Amplifi er
•You are not properly connected to the loudspeakers
•There is no power from the AC socket
•You have the DC trigger jack connected without an appropriate voltage to turn it on
It is obviously important that the GCC Control Amplifi er receive a high level signal from the source (CD, DVD, tuner, etc.) or whatever you are feeding it. One way to determine if this is the case, would be to fi rst go to your loudspeaker. Place your ear very near the tweeter and listen for a very slight hiss. If you hear one, chances are good the amp is working fi ne, connected properly at the speakers and you have an input problem. If you
suspect an input problem, there are several possibilities:
•You have not selected to correct input. Check and make sure the input you selected is the correct input.
•The volume control is too low or the mute is on.
•The source is not playing. Check another source.
•The connecting cables are defective. Use another set.
If you suspect an output problem, use the same technique of placing
your ear very close to the speaker’s tweeter while the GCC Control Amplifi er is turned on. You should hear a very slight amount of hiss from the tweeter. If you do not, check the speaker cable/amp connection. Make sure the amp’s front panel light is on, indicating proper performance.
If there is no sound and you are convinced the GCC Control Amplifi er has power and its front panel light is lit, contact your dealer, distributor or PS Audio for further assistance.
If there is an excessive amount of hiss or noise from the loudspeaker, it is probably not from the GCC Control Amplifi er as this amp has extremely low self noise. Turn the amp off, remove the interconnect cables from the GCC Control Amplifi er and then turn the amplifi er back on. Listen once again to see if the noise has been diminished. If it has, chances are good you either need to replace your source with a quieter one or you may need to experiment with better shielded interconnect cables.
