The GCA- 100 provides up to 100 watts per channel, both channels driven, into an 8 Ohm load and doubles its power rating into a 4 Ohm load. The GCA-250 provides up to 250 watts per channel, both channels driven, into an 8 Ohm load and doubles its power rating into a 4 Ohm load. The GCA-500 provides up to 500 watts per channel, both channels driven, into an 8 Ohm load and doubles its power rating into a 4 Ohm load.

These power amplifi ers are unmatched by any other power amplifi er on the market in terms of performance within their rated power levels and will provide excellent performance in either a two channel or multi-channel environment.
