Plug your subwoofer's AC cord into a wall outlet. Do not use the
outlets on the back of the receiver.
Initially set the Subwoofer-Level Control ¡ to the "min"
position.
Turn on your sub by pressing the Power Switch ¶ on the rear
panel. Turn on your entire audio system and start a CD or movie
soundtrack at a moderate level.

With the Power Switch ¶ in the ON position, the LED § on
the rear panel will remain lit in red or green to indicate the On/
Standby mode of the subwoofer.
RED = STANDBY (No signal detected, Amp Off)
GREEN = ON (Signal detected, Amp On)
The subwoofer will automatically enter the Standby mode after
approximately 10 minutes when no signal is detected from
your system. The subwoofer will then power ON instantly when
a signal is detected. During periods of normal use, the Power
Switch ¶ can be left on. You may turn off the Power Switch ¶
for extended periods of nonoperation, e.g., when you are away
on vacation.
If no sound emanates from the subwoofer, and the power LED is
not on at all, check the AC-line cord. Are the connectors on the
amp side and the AC outlet side fully inserted and making proper
contact? Is the AC plug connected to a "live" receptacle? Has
the Power Switch ¶ been pressed to the "On" position?

Confirm that subwoofer LED § is on and that an RCA cable is
connected from a source unit to the LFE input or L and R inputs
on the sub. Play a CD, record or cassette. Use a selection that
has ample bass information. The LED § on the subwoofer
should turn green. If it remains red, check that the RCA cable
is functioning properly and that it is fully inserted at both ends.
Once you have a green LED, turn your Subwoofer-Level Control
¡ up halfway so that the knob indicator points up. You should
now be hearing bass information coming from the subwoofer.

DJUST EVEL
Set the overall volume control of the preamplifier or stereo
to a comfortable level. Adjust the Subwoofer-Level Control ¡
until you obtain a pleasing blend of bass. Bass response should
not overpower the room but rather be adjusted so there is
a harmonious blend across the entire musical range. Many
users have a tendency to set the subwoofer volume too loud,
adhering to the belief that a subwoofer is there to produce
lots of bass. This is not entirely true. A subwoofer is there to
enhance bass, extending the response of the entire system so
the bass can be felt as well as heard. However, overall balance
must be maintained or the music will not sound natural. An
experienced listener will set the volume of the subwoofer so its
impact on bass response is always there but never obtrusive.

The Phase Switch £ determines whether the subwoofer
speaker's piston-like action moves in and out with the main
speakers, 0,˚ or opposite the main speakers, 180.˚ Proper phase
adjustment depends on several variables such as room size,
subwoofer placement and listener position. Adjust the phase
switch to maximize bass output at the listening position.

ROSSOVER DJUSTMENTS
The Crossover Adjustment Control ™ determines the highest
frequency at which the subwoofer reproduces sounds. If your
main speakers can comfortably reproduce some low-frequency
sounds, set this control to a lower frequency setting, between
50Hz and 100Hz. This will concentrate the subwoofer's efforts on
the ultradeep bass sounds required by today's films and music.
If you are using smaller bookshelf speakers that do not extend to
the lower bass frequencies, set the Crossover Adjustment Control
to a higher setting, between 120Hz and 150Hz.
NOTE: This control will have no effect if the LFE Input ¢ is
used. If you have a Dolby Digital or DTS processor/receiver, the
Low-Pass Frequency is set by the processor/receiver. Consult
your owner's manual to learn how to view or change this setting.

The enclosure may be cleaned using a soft cloth to remove
fingerprints or to wipe off dust.
The grille may be gently vacuumed. Stains may be removed with
an aerosol cleaner, following its instructions. Do not use any
solvents on the grille.
All wiring connections should be inspected and cleaned or
remade periodically. The frequency of maintenance depends on
the metals involved in the connections, atmospheric conditions,
and other factors, but once per year is the minimum.
