The current draw is negligible and keeping it powered on will make sure the internal AC capacitors stay working properly. Are there any internal fuses? There are no user replaceable internal fuses inside the GCC Control Amplifier. There is an internal fuse that should only be replaced by an authorized service center if needed.
® Questions And Answers Owner’s Reference GCC Power Amplifier Series higher wattage model should be considered. What voltages can the amp run on? The GCC Control Amplifier is specific to your country’s voltage. Do not use the GCC Control Amplifier on a voltage higher than it is rated for. For instance, do not take a 120 volt rated GCC Control Amplifier and attempt to use it in a 230 volt country. Failure to observe this cautionary note will void your warranty and may damage the amplifier.
® Troubleshooting Owner’s Reference GCC Power Amplifier Series No sound comes out of the amp If no sound comes out of the GCC Control Amplifier there are several areas to check: Check the input It is obviously important that the GCC Control Amplifier 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 first go to your loudspeaker. Place your ear very near the tweeter and listen for a very slight hiss.
® Troubleshooting Owner’s Reference GCC Power Amplifier Series If you have hum or buzz If you experience a hum through the speakers this can be caused by several things. The first is the source. If there is an excessive amount of buzz or noise from the loudspeaker, it may be caused by a ground loop, a light dimmer in the home, poor AC power, or any number of causes.
® Troubleshooting Owner’s Reference GCC Power Amplifier Series 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 power subwoofer to the outputs of the GCC Series Power Amplifier for some subwoofers. For many subwoofers it will be fine.
