OPTI OWNER'S MANUAL - 16
Before removing your amplifier, refer to the list below and follow the
suggested procedures. Always test the speakers and their wires first.
Check for good ground connection.
Check that remote DC terminal has at least 13.8v DC.
Check that there is battery power on the +terminal.
Check all fuses.
Check that Protection LED is not lit. If it is lit, shut off amplifier briefly
and then repower it.
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.
