The customer is responsible
for proper selection and use
of mounting hardware, avail-
able through hardware stores,
to properly and safely wall-
mount the speakers.

Speaker Connections
Separate and strip the ends of
the speaker wire as shown.
Speakers and electronics ter-
minals have corresponding (+) 
and (–) terminals. It is impor-
tant to connect both speakers
identically: (+) on the speaker
to (+) on the amplifier and (–)
on the speaker to (–) on the
amplifier. Wiring “out of phase”
results in thin sound, weak
bass and a poor stereo image.
Connection Tips
J CenterII/J40Bk OM  7/23/98 9:40 AM  Page 2
If there is no sound from 
the surround speakers,
check the following:
• Check all wires and con-
nections between receiver/
amplifier and speakers. Make
sure all wires are connected.
Make sure none of the
speaker wires are frayed,
cut, or punctured.
• Review proper operation of
your receiver/amplifier and its
surround-sound features.
• Make sure the movie or TV
show you are watching is
recorded in Dolby
*
Surround.
If it is not, check to see if
your receiver/amplifier has
other surround modes you 
may use.
If there is no sound from 
the center speaker, check 
the following:
• Make sure that your 
receiver’s Center Channel 
Mode is in the “normal” or 
“wide” position. If it is in 
the “phantom” position, the
center speaker will not play.
• Check all connections
between processor/amplifier
and the center speaker.
If the system plays at low
volumes but shuts off as
volume is increased, check
the following:
• Check all wires and con-
nections between receiver/
amplifier and speakers. Make
sure all wires are connected.
Make sure none of the
speaker wires are frayed,
cut, or punctured.
• If more than one pair o f
main speakers is being used,
check the minimum imped-
ance requirements of your
receiver/amplifier.
