Surround Modes
When using the TSS-SUB750 in a Dolby Digital or DTS home
theater system, make sure all speakers are set to "Small" . When
using the TSS-SUB750 as part of a Dolby Pro Logic* home
theater system, make sure the receiver's center channel mode
is set to "Normal."
Some Dolby Digital-equipped receivers/processors offer different
setup options for each source or surround mode, e.g., CD-stereo,
videotape, Dolby or Pro Logic. In each case, follow your
equipment's instructions to ensure that the subwoofer output is
turned on and that the speakers are set to "Small" in each mode.
Power On
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
Turn on the subwoofer by pressing the Power Switch
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
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
periods of nonoperation, e.g., when you are away on vacation.
Adjust Level

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 or DVD. Use a selection that has ample bass information.
Set the overall volume control of the receiver/processor to a
comfortable level. Adjust the Subwoofer Level Control
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.

frequency at which the subwoofer reproduces sounds. If your
main/satellite 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 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/Normal Switch
is set to LFE. If you have a Dolby Digital or DTS receiver/
processor, the Low-Pass Frequency is set by the receiver/
processor. Set the LFE/Normal Switch
LFE. Consult your owner's manual to learn how to view or change
this setting. A setting of 100Hz – 120Hz is recommended when
using the TSS-SUB750 with Infinity Total Solution satellites.
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.
Final Positioning
After correctly connecting the TSS-SUB750 system and verifying
that both the subwoofer and all satellite speakers are playing, it
is time to optimize the system for your particular listening room.
Earlier, you placed the subwoofer in its general location. Finding
the exact location for optimal performance sometimes only
involves moving the speakers up to a few inches in any
direction. We urge you, therefore, to experiment with placement,
if possible, until your speakers deliver their full potential.

The satellite and subwoofer enclosures may be cleaned using a
soft cloth to remove fingerprints or to wipe off dust.
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
TSS-SUB750 ever needs service, contact your local Infinity
dealer or Infinity directly at 1.516.674.4INF (USA only) or
