one. Speaker Placement
Proper placement of the
speakers is an important
step in obtaining the
most realistic soundstage
possible. These recom-
mendations are for the
optimum placement of the
loudspeakers. Use these
placement recommenda-
tions as a guide. Slight
variations will not
diminish your listening
pleasure.
The S50 loudspeakers are
video shielded and can
be safely placed near a
television.

Speaker Outputs

Speakers and electronics terminals have corresponding
(+) and (–) terminals. It is important 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.
Troubleshooting
If there is no sound from
any of the speakers,
check the following:
• 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
following:
• Check the “Balance”
control on your receiver/
amplifier.
• Check all wires and
connections between
receiver/amplifier and
speakers.
• Make sure all wires are
connected. Make sure none
of the speaker wires are
frayed, cut or punctured.
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 of
main speakers is being
used, check the minimum
impedance requirements of
your receiver/amplifier.
If there is low bass out-
put, check the following:
• Make sure the polarities
(+ and –) of the left and
right “Speaker Inputs” are
connected properly.
