Owner’s Reference GCHA Headphone Ampliﬁer

If the GCHA Headphone Ampliﬁ er does not power up there are several possibilities: the unit is not getting AC power or the front panel gain control is in the off position.

If you suspect the unit is not getting power, test the receptacle feeding the GCHA power to see if there is power. The easiest way to do this is by using a lamp that you have previously veriﬁ ed works. Regardless of the receptacle’s type, that of a wall receptacle, a power conditioner, Power Plant or AC source of any kind, plug the lamp into the receptacle and verify there is AC power.

Another possibility is the line cord. Swap line cords and make sure the unit has power. Sometimes the line cord feeding the GCHA is not functioning properly.

If the GCHA loses power mysteriously, chances are pretty good that you have the GCHA connected to a switched receptacle on the wall or the

back of a receiver or a power conditioner. Switched AC receptacles are those receptacles that are controlled by a wall mounted power switch and are typically intended to be used to power on/off a lamp in the room. Most times these receptacles are unmarked and inadvertent switching on or off of the power switch can cause a lot of headaches trying to track down the reason your new equipment does not power up. Most switched receptacles are on the top AC receptacle in a two gang box. Always use the lower receptacle on the wall port if you are unsure.

If you have determined the GCHA does

power on, after performing the above tests, turn to the service section of this manual for details on receiving service.

If you are having problems connecting your computer to the GCHA, there are several possibilities:

•The computer does not recognize the USB device

•The computer recognizes multiple USB device possibilities

•The computer uses Windows 98 or older operating software

•The volume control in the computer is turned down

If the computer does not recognize the GCHA as a USB device, leave the GCHA plugged in to its power, leave the USB cable connected to the computer and reboot the computer. The computer should open the Found New Hardware dialog and install the USB device. If it does not recognize there is new hardware, then either it has been installed (therefore the hardware is no longer “new”)
