PLACEMENT
NOTE: The satellite speakers can be placed directly on a shelf, or mounted on a wall using the
built-in bracket (see Figures 3 through 6).
For front left and right channels, place the speaker on the left and another on the right.
For the center channel, place the speaker directly on top of, or below, your television.
FRONT CHANNELS...
CENTER CHANNEL...
Since the speakers are magnetically shielded, you can place them very close to the TV without
worrying about the magnetic field distorting the TV picture.
SURROUND CHANNELS...
SUBWOOFER...
For surround left and right channels, place one speaker on the left and another on the right, to
the side of, or behind the listening area.
Since installing a subwoofer can be somewhat more complicated than installing full-range
speakers, it is essential you read this section very carefully prior to connecting the subwoofer to
your system. Should you have questions relating to your installation, it is advisable to call either
your dealer or Infinity’s Customer Service Department for advice.
The performance of the subwoofer is directly related to its placement in the listening room and
how you align the subwoofer with its satellite speakers. Setting the volume of the subwoofer in
relationship to the left and right speakers is also of critical importance because it is essential that
the subwoofer integrates 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 effect of the subwoofer.
CAUTION: The metal plate on
the back of the subwoofer
acts as the heat sink for the
subwoofer’s internal amplifier.
It is normal for this area
to get warm.
We recommend placing the subwoofer at least 2 to 3 feet away from a television or a computer’s
disc-drive system to prevent distorting the colors of the TV picture or erasing the magnetic drive.
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 the 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 and the amount and quality of bass required. Never
place the port too close to a wall or piece of furniture as this will prevent the port from
operating properly. Since the port is an integral part of the subwoofer’s design, it should always
be permitted free access to the listening room without obstruction to the pressure emerging from
it. Careful experimentation will enable you to determine the best position for the subwoofer (see
useful hints, next page).

PRIMARY
LISTENING
AREA
Here are some useful hints:
1. Experimentation with the port direction may be useful. At times directing the port away
from the listening area (to the side) may be advantageous because this may create a better
blend of bass within the listening room.
2. If bass response seems inadequate, move it closer to a wall or corner. If bass becomes too
heavy, try turning the subwoofer with the port facing away from the wall. This will tend to
diminish bass output.
It may take some time and patience to find the most pleasing acoustic location for your sub-
woofer. Testing for sonic balance and blending should always be made for your normal listening
position, using a wide range of source material. As a starting point, place the subwoofer behind
your right-channel satellite speaker, about 3 or 4 inches from the wall. We suggest trying this
location first because the bass instruments in an orchestra are usually located in the back and to
the right (see Figure 2).

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.
WALL-MOUNTING THE SATELLITES
The satellite speakers can be wall- or ceiling-mounted, as shown in Figures 5 and 6. You can
mount the speakers with #6 wood screws (not included), using the built-in mounting bracket.
Use the enclosed template to mark the desired position of each speaker on a wall or ceiling.
Locate a stud for secure mounting and use heavy-duty wood screws with long threads. Test
the mounting thoroughly before installation.
To mount the speaker vertically on a wall, fasten the wood screws (not included) to a
wall stud, leaving a 3⁄16" clearance between the base of the screw head and the wall. If desired,
loosen the bracket screw, adjust the bracket angle, and tighten the bracket screw.

WIRING THE SPEAKERS
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. If you need more wire than is
provided, use at least #16 gauge speaker wire with polarity coding. 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, receiver, or television to confirm connection
procedures.
SATELLITES...
IMPORTANT!
On the back of the satellite, loosen the bracket screw and rotate the bracket to access terminals.
Observe polarities when making speaker connections, as shown in Figure 7. 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.
Do not reverse polarities (i.e., + to – or – to +) when making connections. Doing so will cause
poor imaging and diminished bass response.

A FEW SUGGESTIONS
We recommend that you not operate your speakers or subwoofer with the bass, treble and loud-
ness controls set to full boost. This will place undue strain on your electronics and speakers and
could damage them.
The volume control setting on your preamplifier or stereo 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.
Always turn down the volume control setting on your preamplifier or stereo when changing a cas-
sette or CD, or switching inputs to AM or FM operation. Excessively loud transients (clicks or
popping sounds) can damage the satellite speakers and possibly the subwoofer.
IMPORTANT!
Whenever changing cables, pulling plugs, etc., ALWAYS TURN OFF ALL EQUIPMENT, includ-
ing the subwoofer. This prevents transients from entering the speakers and prevents electrical
energy from reaching you. Keep all connections out of the reach of children.
OPERATING THE SYSTEM
Check the speakers for playback by first setting the audio system volume control for a
minimum level, and then applying power to your system. Play a favorite music or video
segment and increase the volume control to a comfortable level.
CHECKING PLAYBACK...
SURROUND MODES...
NOTE: You should hear balanced audio reproduction across the entire frequency spectrum. If not, check all
wiring connections and see In Case of Trouble for more help.
When using the HTS-20 System in a Dolby* Pro Logic* home-theater system, make sure the
receiver’s center-channel mode is set to “Normal”. When using the HTS-20 system in a Dolby
®
®
Digital or DTS home-theater system, make sure the receiver’s speaker modes are set to “Small”.
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 is turned on and that the speakers are set to “Small”
in each mode.
OPERATING THE SUBWOOFER
1. Initially set the subwoofer’s Volume control
◆ (Fig. 10) to the minimum position.
SET CONTROLS...
2. If you are using a receiver or surround processor containing a Dolby Digital and/or DTS
decoder, set the crossover bypass switch to “On”. If you are using a stereo or Dolby Pro Logic
receiver, set this switch to “Off”.
POWER
ON...
3. Turn on your entire audio system and play any music source.
4. Turn the Volume control
◆ (Fig. 10) to its mid-position. If no sound emanates from the sub-
woofer, 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?
◆

5. Set the overall volume control of the preamplifier or receiver to a comfortable level. Adjust
the subwoofer’s Volume control (Fig. 10) until you obtain a pleasing blend of bass. Bass
ADJUST VOLUME...
◆
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 vol-
ume too loud, following 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;
otherwise, 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 is never obtrusive.
6. Room placement of the subwoofer is also an important aspect of its installation. It may be
necessary for you to try various locations in your listening room before you choose the final
location. Some possible starting points include: behind the right-channel satellite speaker,
along the back wall between the satellites, along a side wall, or behind a couch or a chair.
ROOM PLACEMENT...
In general, the closer the subwoofer is to walls and corners, the greater the effect of low-
frequency enhancement. Experiment with its placement and Volume control until you are
pleased with the result you obtain from your particular application.
A WORD OF ADVICE
The Volume control may be set anywhere within its rotation. However, it will be most unusual
if you have to turn the Volume control completely clockwise. This may indicate an unbalanced
condition in your system (too much bass) or an especially large room, or room placement may
not be correct. Try several other locations before concluding that the Volume control must be set
at maximum.
CARE OF YOUR SPEAKER SYSTEM
The satellites and powered subwoofer enclosures do not require any routine maintenance. When
needed, use a soft cloth, dampened with water only, to remove any fingerprints or to wipe off
dust. Clean the grille by gentle vacuuming or with a damp cloth.
NOTE: Do not use any cleaning products or polishes on the enclosures or grilles.
IN CASE OF TROUBLE
Before consulting your dealer, try these simple troubleshooting steps:
•
•
•
•
•
If the sound quality is distorted, listen to each speaker separately.
If distortion is present in both, the problem is probably somewhere else in your system.
If only one channel is distorted, switch the left and right speaker leads at the receiver.
If the distortion moves to the other speaker, the problem is not in the speaker.
If you need further assistance, contact your local Infinity retail dealer.
