Getting Started

Owner’s Reference GCA Power Amplifier Series

Location

Cautions

Once your new GCA Series Power Amplifi er is unpacked, you’ll need to fi nd a convenient place to set it.

There are several ways to mount the GCA Series Power Amplifi er: on a rack shelf, on the fl oor behind the loudspeakers or on shelf near your preamplifi er.

If the GCA Series Power Amplifi er is to be placed on the fl oor or carpet, make sure the unit is not going to come in contact with water or cleaning solvents. Make sure the carpet does not interfere with airfl ow to the amp.

Isolation

Power Cables

Conditioners

The GCA Series Power Amplifi er can benefi t from aftermarket isolation devices such as cones, spikes and Sorbothane pads.

Once you have chosen the location for the GCA Series Power Amplifi er you can use the supplied AC power cord to connect it to the AC wall receptacle 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 GCA Series Power Amplifi er power. While the supplied power cable is adequate for the task 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.

We recommend the use of power conditioning equipment, such as a PS Audio Power Plant, UPC- 200 or any of the Ultimate Outlet or Power Director series from PS. We do not recommend the use of simple AC fi lter power conditioners not made by PS Audio as most of these will ”bleach” the sound and rob the music or video soundtrack of life and dynamics. If you do not use PS Audio power conditioning equipment, you would be advised to plug the GCA Power amplifi er directly into the AC wall receptacle.
