OPERATION
Power On
Plug your subwoofer’sAC 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.

¶
on
the rear panel.
Turn on your entire audio system and start a CD or movie
sound-track at a moderate level.
Auto On/Standby
With the Power Switch
¶
in the ON position, the LED on the
front 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.
Adjust Level
Turn your Subwoofer-Level Control
¡
up to the “5”position
(halfway). If no sound emanates from the subwoofer, check the AC-
line cord and input cables.Are the connectors on the cables
making proper contact? Is the AC plug connected to a “live”
receptacle? Has the Power Switch
¶
been pressed to the “On”
position? Once you have confirmed that the subwoofer is active,
proceed by playing a CD, record or cassette. Use a selection that
has ample bass information.
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.
Phase Control
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.
Crossover Adjustments
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.
MAINTENANCE AND SERVICE
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.
If a problem occurs,make sure that all connections are properly
made and clean. If a problem exists in one loudspeaker, reverse
the connection wires to the left and right system. If the problem
remains in the same speaker, then the fault is with the loud-
speaker. If the problem appears in the opposite speaker, the
cause is in another component or cable. In the event that
your subwoofer ever needs service,contact your local
Infinity dealer or Infinity directly at 1.800.553.3332 or
