Once you have decided on the location and chosen the appropriate power cables, you are ready to
install the GCC Control Amplifi er.
We would recommend that you power the entire system down before attempting to insert the GCC
Control Amplifi er.
Insert the GCC Control Amplifi er into the system.
Connect the inputs of the GCC Control
Amplifi er to the output of your source
equipment such as CD players, phono
preamplifi ers, tuner, etc. There are two
choices of inputs: balanced or single
ended. There is one balanced input and
four single ended RCA inputs.
Balanced inputs require a source that
has a balanced output. These outputs
are the preferred method of connection
as a balanced XLR type of output allows
the lowest noise connection, and allow
owners to take advantage of the high
common mode rejection characteristics found in the Gain Cell of the GCC Control Amplifi er. Be sure
to use a high quality well shielded and well regarded interconnect for this critical link. PS Audio makes
an entire line of excellent choices for interconnects, perfectly matched to your equipment’s needs.
RCA or single ended inputs will be the typical inputs as many sources have only this standard type of
input. Be sure to use a high quality well shielded and well regarded interconnect for this critical link.
Speaker cables are a critical link between your loudspeakers and your new GCC Control Amplifi er.
Make sure you use only the highest quality such as a PS Audio speaker cable that will be perfectly
matched to your equipment’s needs.
Pay close attention to the polarity on the rear panel binding posts. It is critically important that you
match plus and minus (red and black) of the GCC Control Amplifi er to the plus and minus of your
speaker. Carefully observe the polarity. The plus or red terminal of the GCC Control Amplifi er must
eventually be tied to the plus or red terminal of your loudspeaker. The GCC Control Amplifi er is a non-
inverting amplifi er design meaning it is in phase with the input signal.
Use the Aux Out RCA connectors on the rear of the GCC Control Amplifi er to feed your subwoofer’s
low level inputs. Some subwoofers have high level inputs where the output of the amplifi er can be
connected as an input to the subwoofer. Generally there is no problem. In a few rare instances there
may be a problem, which will show itself as problematic if the amp’s protection comes on after hooking
up the sub. REL subwoofers and some Sunfi re subwoofers can be problematic. Please check with
the factory or your dealer if you encounter these subwoofers or any problems.
