INTRODUCTION  
The Infinity HTS-20 is a compact, efficient universal satellite, center-channel and subwoofer system  
that is ideal for reproducing home-theater sound. With their versatile design, the satellite speakers  
can be placed virtually anywhere on shelves or stands, or mounted on a wall or ceiling using the  
integral 4-way mounting bracket. The bracket has crossholes for mounting and also acts as a door  
for hiding the connection terminals. The center channel can easily be placed on top of or on a shelf  
below the television. The powered subwoofer delivers tremendous bass performance from a  
compact, easy-to-place design.  
To start enjoying your new HTS-20 Home-Theater System, read and then follow all instructions  
listed in this manual, as well as those found in the owners manuals of associated components in  
your audio system. Save all instructions for future reference.

PLANNING YOUR SYSTEM  
The satellite speakers are used to reproduce sound for front and surround channels. Before deciding  
where to best place your speakers, survey your room and study Figure 1.

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 Infinitys 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 subwoofers 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  
subwoofers 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 computers  
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 subwoofers 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 316" 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.  
VERTICAL MOUNTING...  
NOTE: You may want to route the wires before tightening the bracket screw (see Figure 8 on page 11).  
Then orient the speaker vertically, align the crossholes on the rear of the speaker with the wood  
screws, and slide the speaker down.

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 owners  
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  
receivers 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 receivers 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 equipments  
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 subwoofers 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 livereceptacle?  
16 HTS-20 Home-Theater System Owners Manual  
 
5. Set the overall volume control of the preamplifier or receiver to a comfortable level. Adjust  
the subwoofers 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.
