POWER MODE- MANUAL.AUTO ON.TRIGGER
1. Manual- When you wish to manually turn the amplifier on and off by using the front
panel power button
2. Auto on- When you want to the amplifier to turn on when the amplifier’s receives an
audio signal. Either the left or right input jacks receive a signal the amplifiers is turned
on. Once the signal stops the amplifier waits 5 minutes and then turn off.
3. Trigger- If you wish the amplifier turn on when it receives voltages (5V-12VDC) from
an external source and turn off once that voltage has stopped. The voltage source
must be connected to the trigger input 3.5 jack on the back of amplifier.
12V DC CONTROL OUT

NOTE
The GFA-575se is polarity correct; that is, it does not invert "phase". Any positive-going
signal at its inputs will appear as a positive-going signal at its outputs.
The RIGHT STEREO OUTPUT should be connected to the right-channel loudspeaker, as
you face the pair of loudspeakers, and the LEFT STEREO OUTPUT to the left-channel
loudspeaker.
Be certain, when the GFA-575se is used in Its stereophonic mode, the
STEREO/BRIDGED MONO INPUT switch is in the STEREO position. Otherwise, the
amplifier will not operate in the stereo mode. You will amplify only the left channel through
both outputs of the amplifier. For further clarification, please refer to the section
STEREO/BRIDGED MONO INPUT/OUTPUT.
In order to insure that connections to the loudspeakers are correct, you must be able to
identify each wire conductor of the loudspeaker cables at both ends of the cables. This is
relatively easy to do since most loudspeaker cables consist of two parallel, stranded
conductors in a flexible insulation, with a coding system for wire identification. Sometimes
there is a colored "tracer" wrapped around one of the conductors; some cords have one of
the conductors colored silver and the other copper; some have a "ridge" molded on the
insulation on one of the conductors, while others are marked with a "+" and/or "_". Your
ADCOM dealer also sells special loudspeaker interconnecting cables and these are most
often labeled with respect to polarity.
