Owner’s Reference GCHA Headphone Amplifi er
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.
