Once your new GCHA is unpacked, you’ll need to fi nd a convenient place to set it.

There are several ways to mount the GCHA: on a shelf next to the preamplifi er, CD or DVD player, or on a desk or table near your computer.

The GCHA can benefi t from aftermarket isolation devices such as cones, spikes and Sorbothane pads.

Once you have chosen the location for the GCHA you can use the supplied AC power cord to connect it to the AC wall receptacle to get started, or you can use an aftermarket power cord and receptacle.

We strongly recommend the use of a PS Audio xStream Power™ AC cable and a PS Power Port™ AC receptacle to feed the GCHA power. While the supplied power cable is adequate for the task of setup it is not going to provide the best performance. Choosing any xStream Power cable will make a signifi cant performance improvement over the stock power cable. An xStream Plus would be our recommendation.

It is further recommended that you power the GCHA with a PS Audio Power Plant if possible, or a UPC-200 or Ultimate Outlet if not. Power conditioning with the appropriate equipment will further the benefi ts of the GCHA headphone amplifi er.

Connections from the analog audio source should be through high quality audio interconnects with proper shielding. Using inexpensive, off-the-shelf audio interconnects should be avoided if you expect the full benefi ts of this high-end audio amplifi er to be available. We would recommend using audio interconnects less than 3 meters in length. PS designs and sells a line of reference quality audio interconnects that are highly recommended. Please see your PS dealer for details.

Connections from the computer to the USB input of the GCHA should use a high quality, properly shielded USB-2.0 cable. Each GCHA has a supplied and approved USB cable included.
