Introduction
Thank you for your purchase of the GCC series Control Amplifi er. This document covers the three
stereo Control Amplifi er models, GCC-100, GCC-250, GCC-500.
Control Amplifi ers are actually Variable Gain Power Amplifi ers™ with multiple inputs. Users can select
any one of 5 input sources and control the gain of the power amplifi er via the front panel control or
through the supplied remote control, which results in the volume to the speakers being controlled.
Control Amplifi ers are unique in the world of audio and are the shortest and purest audio path of any
product on the market. While Control Amplifi ers resemble an integrated amplifi er in their operation,
they are not integrateds.
Integrated amplifi ers are a marriage of a preamplifi er, or input volume attenuator and a power amplifi er.
Because of the PS Audio Gain Cell™, the GCC Series of products do not attenuate the input signal
and do not “throw away” the unwanted signal. Instead, the GCC Control Amplifi ers vary their gain in
response to the user’s front panel or remote commands.
This creates the world’s fi rst Variable Gain Power Amplifi er™, or the GCC Control Amplifi er.
Each of the three Control Amplifi er models is a dual mono Control amplifi er, capable of driving nearly
every loudspeaker load with ease and beauty.
GCC power amplifi ers are based on our unique and proprietary Gain Cell technology for the input
electronics and SDAT Class D switching power amplifi cation for the output.
The GCC series have high effi ciency digital amplifi cation stages that allow them to run cool to the
touch even while driving demanding loads and should offer years of trouble free performance of the
highest standards.
Power ratings for each model are designated by their naming scheme into an 8 Ohm load. The GCC-
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 GCC-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 GCC-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.
You should expect state of the art performance and sonics from any of the GCC Series Control
Amplifi ers. These Control Amplifi ers are unmatched by any other power amplifi er/preamplifi er
combination 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.
