If there is no sound from any
of the speakers:
• Check that the receiver/
amplifier is on and a source
is playing.
• Review proper operation of
your receiver/amplifier.
If there is no sound 
coming from one speaker:
• Check the ‘Balance’ control
on your receiver/amplifier.
• Check all wires and connec-
tions between receiver/
amplifier and speakers.
• Make sure all wires are con-
nected. Make sure none of
the speaker wires are frayed,
cut or punctured.
If the system plays at low vol-
umes but shuts off as volume
is increased:
• Check all wires and connec-
tions between receiver/
amplifier and speakers.
• Make sure all wires are con-
nected. Make sure none of
the speaker wires are frayed,
cut or punctured.
• If more than one pair of
speakers is being used,
check the minimum imped-
ance requirements of your
receiver/amplifier.
If there is no (or low) bass
output:
• Make sure the polarities 
(+ and -) of the left and right
‘Speaker Inputs’ are con-
nected properly.
*The maximum recommended amplifier power 
rating will ensure proper system headroom to 
allow for occasional peaks. We do not recomm
end sustained operation at these maximum power
levels.
