SYMPTOM	POSSIBLE CAUSES AND TEST PROCEDURE
No sound on one channel	BusMatrix DIP switch is not in the correct position.
	Check your configuration worksheet for the correct
	setting and verify.
	Short circuit or loose wire at speaker or amplifier
	terminals. Check that connections are secure and
	that there are no loose strands of wire crossing from
	the positive to the negative terminal at the back of
	the amplifier and the speaker.
	Short circuit or a break in the speaker wire. Dis-
	connect the speaker wire at both ends, separate the
	2 conductors at both ends and test with a meter for
	a short circuit. If there is no short, connect the two
	conductors at one end and test with a meter for
	continuity.
	Speaker is not working. Connect the speaker to a
	channel that plays another speaker.
	Audio cable to dedicated input is bad. Connect the
	non-working channel input to another cable that is
	known to be good.
	Bridging Switch is in the wrong position. Check
	your configuration worksheet for the correct setting
	and verify.
	The thermal protection circuit has operated because
	of overheating caused by overdriving or inadequate
	ventilation.
No sound on some or all	BusMatrix DIP switches are not in the correct posi-
channels	tions. Check your configuration worksheet and
	verify all settings.
	Audio cable to the main bus inputs is bad. Connect
	the non-working channel input to another cable
	that is known to be good.
	Some or all of the internal amplifier fuses are blown.
	(Return the amplifier to your dealer for service).
