Owner’s Reference GCHA Headphone Amplifier

What voltages can I run GCHA on?

Turning the unit on/off

The GCHA is specifi c to your country’s voltage. Do not use the GCHA on a voltage higher than it is rated for. For instance, do not take a 120 volt rated GCHA and attempt to use it in a 220 volt country. Failure to observe this cautionary note will void your warranty. If you need to operate the GCHA at a voltage other than the voltage it was designed for, contact your dealer, distributor or the factory for help.

The GCHA should generate a bit of heat, especially on the bottom of the unit. This is normal. The GCHA will remain warm to the trouch even when the front panel Gain Control is in the off position.

We do not recommend removing power to the GCHA. We recommend leaving the GCHA powered at all times.

The front panel gain control on the GCHA also serves as the on/off switch. Turning the gain control fully counter clockwise you will feel a “click”. The front panel blue LED should shut off and the GCHA output will be muted. This does not remove power from the GCHA and it will remain on. We recommend leaving the GCHA powered up at all times.
