Once you have decided on the location and chosen the appropriate power cables, you are ready to
install the GCA Series Power Amplifi er.
We would recommend that you power the entire system down before attempting to insert the GCA
Series Power Amplifi er.
Insert the GCA Series
Power Amplifi
er into
the system.
Connect the inputs of
the GCA Series Power
Amplifi er to the output
of your preamplifi
er,
surround processor or
preamp outputs of a
receiver or integrated
amplifi
er. There are
two choices of inputs:
balanced or single
ended. Once chosen,
you must switch to the
appropriate input via
the rear mounted input selection switch on the GCA Series Power Amplifi er.
Balanced inputs require a preamp or 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
between preamp and power amp, and allow owners to take advantage of the high common mode
rejection characteristics found in the Gain Cell of the GCA Series Power 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 preamplifi ers, surround processors,
receivers and integrated amplifi ers have only this standard type of input. 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.
Make sure the rear mounted input selection switch is placed in the appropriate position, either XLR or
RCA (balanced or single ended). The switch must match the input you are using. Only one input on
the GCA Series Power Amplifi er can be used at a time, either XLR or RCA.
Speaker cables are a critical link between your loudspeakers and your new GCA Series Power
Amplifi er. Make sure you use only the highest quality. PS Audio makes an entire line of excellent
choices for speaker cables, perfectly matched to your equipment’s needs.
