Before removing your amplifier, refer to the list below and follow the
suggested procedures. Always test the speakers and their wires first.
Disconnect all RCA inputs to the amplifier(s)-if hiss / noise disappears, then plug
in the component driving the amplifier and unplug its inputs. If hiss / noise
disappears, go on until the faulty /noisy component is found.
It is best to set the amplifier’s input level as insensitive as possible. The best
subjective S/N ratio is obtainable this way. Try to drive as high a signal level from the
head unit as possible.
