If this happens:
No sound from any speaker with any source
No sound from one speaker
No sound from the rear surround speakers
Well then:
Still doesn't work?
Still doesn't work?
If the cable is loose, tighten it. Turn the
system off and then back on again. Still
doesn't work?
Push the MUTE button on the front panel or
remote once to turn off the MUTE light and
resume sound.
If it isn't glowing at all, disconnect the sub-
woofer AC cord from the wall socket and
remove the fuse that is near the sub-
woofer's Power switch. If it is blown or if
you are in doubt, replace it with an identical
fuse. DO NOT USE ANY VALUE FUSE
OTHER THAN THAT INDICATED.
Still doesn't work?
If the radio plays but not any other source,
double check all the connections for the
other sources, make sure they are on and in
the play mode. If the FM radio doesn't play,
press the “SAVE PRESET,” “CLEAR,” and
“PRESET UP” buttons all at the same time
to preset the preamp processor. If that
doesn’t work, call your dealer or Polk Audio.
Still doesn't work?
If the “new” speaker doesn't play, the fault
is in the either the connection, speaker
wire, power amplifier or preamp/processor
and NOT the speaker. Call your dealer or
Polk Audio. If the “new” speaker does play,
the fault lies with the original non-function-
ing speaker.
Still no surround channels?
Still no suround channels?
Try a source that you know for a fact is
stereo or multi-channel. If that doesn't
work, call your dealer or Polk Audio.
Try this:
Make sure the volume isn’t turned down all
the way. Try setting it to –20dB.
Make sure the subwoofer is plugged in to a
live AC outlet and that the power switch on
the back of the sub is set to “Standby.”
Make sure the 4 meter cable that connects
preamp/processor and subwoofer is firmly
inserted and screwed in.
Make sure the MUTE light is not lit on the
front panel display.
Check the small pilot light on the bottom of the
subwoofer enclosure, just above the base. It
should be glowing either red or green.
Try playing an FM radio station
Double check all speaker wire connections at
the amplifier and the speakers to make sure
they are secure.
Disconnect the silent speaker from its speaker
wires and replace it with a working speaker
from another channel.
Press the Surround button on either the
remote control or front panel until either PRO
LOGIC, 5CH SURND, DOLBY DIG or DTS
appears in the display window. Note: a DVD-
Audio disc that is recorded in 2 channel stereo
will not play in a surround mode like Pro Logic
or 5 Channel Surround while playing through
the 6 CH AUDIO inputs. See page 24 for more
information.
Check surround channel levels and make sure
that they are not set too low. Reset to 0dB or
higher (see page 20).
If you are listening to a TV or FM broadcast, it
is possible that the broadcast is not in stereo.
The surround processor must have at least a
stereo signal to derive surround sound.
