Subwoofer Adjustment & Use
Subwoofer initial control settings
• Set the LOW PASS FREQUENCY Control to its center position.
• Set the LEVEL Control fully counterclockwise to MIN. You’ll reset this
control after you make other adjustments
.
Adjusting the Subwoofer controls
• Play a program on your system. Use a Dolby® Digital or Dolby® Pro-
logic signal, or a music CD. Adjust the Receiver’s volume control for a
comfortable sound level from the system speakers.
• Increase the Subwoofer’s LEVEL Control setting clockwise, so that you
hear the deep bass. Adjust the control for a natural, musical balance
that has plenty of deep bass sound when it’s actually present in the
music.
• Listen carefully to bass voices and, if needed, adjust the LOW PASS
FREQUENCY Control so that they sound natural. Setting the
frequency too high will make deep voices sound excessively “chesty”
or resonant and will give the upper bass in music a “one-note” quality.
Setting the frequency too low will make deep voices sound “thin” and
will give music a lack of “warmth.”
• Adjust the Phase Control for maximum bass response. The phase
control can help to align the bass of the Subwoofer with the bass
response of other speakers in the system. Listen to a piece of music
with the Phase Control in one setting. Change the setting on the
switch and listen for an increase or decrease in the bass response.
One setting should produce better bass response. If there is no
change, then your subwoofer and speakers are aligned properly in
either position
.
• Make fine adjustments until the program has satisfying and natural
sound quality on both bass voices and music
.
Troubleshooting
Subwoofer POWER Indicator LED does not light
• Check that the Subwoofer’s POWER switch is in the AUTO ON
position.
• If the POWER Switch is in the AUTO ON position, check the AC outlet
the Subwoofer is plugged into to be sure that it is live. You can use a
tester or plug in a lamp to check it.
• If the AC outlet is live, either the power cord or Subwoofer has a
problem. Unplug the power cord from the AC outlet and check the fuse
by unscrewing the center piece from the holder. If it is blown, replace
the fuse only with a fuse of the same type and rating. If this doesn’t
help, take the Subwoofer to your dealer for service — THERE ARE NO
USER-SERVICEABLE PARTS INSIDE.
No sound from the Front speakers
• Be sure the Receiver and Subwoofer POWER switches are in the ON
positions.
• Check the Receiver’s Volume Control setting — if it is all the way
down, there won’t be any sound.
• Check that the Receiver’s Input Selector is set to an active source of
audio signals and that a Tape Monitor Loop is not engaged.
• Be sure that the Receiver’s Speaker Selector switch is turned on to the
terminals [A or B, 1 or 2] that you have your Front speakers connected
to. If the Receiver has a headphone jack, you can use headphones to
check the Receiver for output.
• Check the wires and connections from the Receiver’s Front Speaker
Output terminals to the Subwoofer’s SPEAKER-IN
terminals.
• Try removing the Subwoofer from the system, leaving your Front
speakers connected to the Receiver. If there still is no sound, take the
Receiver to your dealer for service.
• Try removing the Subwoofer from the system, leaving your Front
speaker connected to the Receiver. If there still is no sound, take the
Receiver to your dealer for service.
No sound from the Subwoofer
• First, be sure there is sound from the Front speakers and that the
Receiver is working correctly as outlined above.
• Check the Subwoofer’s LEVEL control. If it is all the way counterclock-
wise, there may be no sound.
• The Subwoofer only reproduces deep bass sound. If the program has
no deep bass, the Subwoofer will not make any sound. Play a program
with plenty of bass, such as jazz or rock music, or an action movie.
• If everything else checks OK, take the Subwoofer to your dealer for
service - THERE ARE NO USER-SERVICEABLE PARTS INSIDE.
