WALL-MOUNTING THE SATELLITES
PLACEMENT
NOTE: The satellite speakers can be placed directly on a shelf,
or mounted on a wall using the wall brackets included.
The TSS-750 satellites are designed to be mounted on the wall.
There is a wall bracket for each satellite speaker.
NOTE: The customer is responsible for the correct selection
and use of mounting hardware (available through hardware stores)
that will ensure the proper and safe wall-mounting of
the speakers.
Left and Right Front Channels
For left and right front channels, place one satellite to the left and
another to the right of the television, as shown in Figure 1.
Since the speakers are magnetically shielded, you can place them
very close to the TV without worrying about the magnetic field
distorting the picture.
Step 1.
Mark the positions on the wall where you would like to place the
mounting screws.
Center Channel
For the center channel, place the speaker directly on top of,
or below, your television. Use a shelf if the television does not
provide a stable platform.
Step 2.
Place bracket against wall and fasten two appropriate screws
through the bracket’s screw holes into the wall.
Step 3.
Surround Channels
Place the speaker on the wall by sliding the opening on the bottom
of the speaker over the bracket hook on the wall. Once positioned
properly, the speaker should slide down slightly and become
secure.
For left and right surround channels, place one speaker on the left
and another on the right, to the side of or slightly behind the
listening area.The surround speakers should be mounted at a
height of between 1.2 and 2 meters.
keyhole on the back of the speaker to the screwhead on the wall.
Once positioned properly, the speaker should slide down slightly
and become secure.
Subwoofer
Since the installation of a subwoofer can be somewhat more
complicated than installing full-range speakers, it is essential that
you read this section very carefully prior to connecting the
subwoofer to your system. Should you have questions relating to
installation, it is advisable to call either your dealer or Infinity’s
Customer Service Department for advice.
Figure 3.
The performance of the subwoofer is directly related to its
placement in the listening room and how you align the subwoofer
with the satellite speakers. Setting the volume of the subwoofer
in relation to the left and right speakers is also of critical
importance because it is essential that the subwoofer integrate
smoothly with the entire system. Setting the subwoofer’s volume
level too high will result in an overpowering, boomy bass. Setting
the volume level too low will negate the benefits of the subwoofer.
®
Here are several additional facts on installation that may prove
useful. It is generally believed that low frequencies (below 125Hz)
are nondirectional and, therefore, placement of a subwoofer within
any listening room is not critical.While in theory it is true that the
larger wavelengths of extremely low frequencies are basically
nondirectional, the fact is that, when installing a subwoofer within
the limited confines of a room, reflections, standing waves and
absorptions generated within the room will strongly influence the
performance of any subwoofer system.As a result, specific
location of the subwoofer becomes important, and we strongly
recommend that you experiment with placement before choosing a
final location. Placement will depend upon your room (for example,
whether or not your room permits placement of the subwoofer near
either satellite) and the amount and quality of bass required.

CENTER AND SATELLITE SPEAKER CONNECTIONS
Turn Off All Power
After placing the speakers, you are ready to connect your system.
First, turn off all audio-system power. Use high-quality speaker wire
to make your connections. Speaker wire with polarity coding is
included. For longer distances, heavier gauge wire is recommended.
The side of the wire with a ridge or other coding is usually
considered positive polarity (i.e., +). Also, consult the owner’s
manuals that were included with your amplifier or receiver to
confirm connection procedures.
Center Channel
Observe polarities when making speaker connections, as shown in
Figure 5. Connect each + terminal on the back of the amplifier or
receiver to the respective + (red) terminal on the speaker. Connect
the – (black) terminals in the same way.
Important!
Do not reverse polarities (i.e., + to – or – to +) when making
connections. Be certain that positive and negative wire strands are
completely isolated to avoid short circuits that may damage your
equipment.
Satellites
Observe polarities when making speaker connections, as shown in
Figure 4. Connect each + terminal on the back of the amplifier or
receiver to the respective + (red) terminal on each speaker.
Connect the – (black) terminals in the same way.
–
+
Important!
Do not reverse polarities (i.e., + to – or – to +) when making
connections. Doing so will cause poor imaging and diminished
bass response. Be certain that positive and negative wire strands
are completely isolated to avoid short circuits that may damage
your equipment.
Figure 5.The satellites and center channel speaker feature
terminals that can be connected in several different ways; e.g.,
spade terminals and direct wiring (as shown here).

We recommend that you do not operate your speakers or subwoofer
with the bass, treble and loudness controls set to full boost.
This will place undue strain on your electronics and speakers and
could damage them.
LINE LEVEL IN
For LFE use L or R
The volume control setting on your processor/preamp or receiver
is not a specific indication of the overall loudness level of the
speakers.The only important consideration is the loudness level
at which the system can be played, regardless of where the volume
control is set.

OPERATION
Surround Modes
Crossover Adjustment
When using the TSS-750 in a Dolby Pro Logic* home theater
system, make sure the receiver’s center channel mode is set to
“Normal.”When using the system in a Dolby Digital or DTS home
theater system, make sure all speakers are set to“Small”.
The Crossover Frequency Control ꢀ determines the highest
frequency at which the subwoofer reproduces sounds. For the
TSS-750, it is recommended that this control be set at 120Hz
(approximately the 3 o’clock position).
Some Dolby Digital-equipped receivers/processors offer different
setup options for each source or surround mode, e.g., CD-stereo,
videotape, Dolby, 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.
NOTE: This control will have no effect if the LFE/Normal Switch ᕢ
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 ᕢ on the subwoofer to LFE. Consult your
owner’s manual to learn how to view or change this setting.
A setting of 120Hz – 150Hz is recommended.
Power On
Plug your subwoofer’s AC cord into a wall outlet. Do not use the outlets
on the back of the receiver.
Phase Control
The Phase Switch ᕣ 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
Auto On/Stand-By
After correctly connecting the TSS-750 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 optimum performance sometimes only involves moving
the speakers up to a few centimeters in any direction.We urge
you, therefore, to experiment with placement, if possible, until your
speakers deliver their full potential.
ᕦ
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/Stand-By
mode of the subwoofer.
RED = STAND-BY (No signal detected,Amp Off)
GREEN = ON (Signal detected,Amp On)
The subwoofer will automatically enter the Stand-By mode after
approximately 10 minutes when no signal is detected from your
system.The subwoofer will then power ON instantly when a signal

cables.Are the connectors on the cables making proper contact? Is
the AC plug connected to a“live”receptacle? Has the Power Switch
ᕦ
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.
In the event that your TSS-750 ever needs service, contact your
local Infinity dealer or distributor.
Set the overall volume control of the receiver/processor to a
ᕡ
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 sub-
woofer so its impact on bass response is always there but never
obtrusive.
