Introduction
NOTE: Check your system immediately. If it has been damaged in transit, report the damage immediately by calling your AR dealer.
Please follow the directions in this manual to achieve the best performance from your
system.
The hook-up and operation of the subwoofer is the same for a home theater surround
system and a stereo music system. The subwoofer has a built-in amplifier, making it
compatible with any sound system. In addition, the subwoofer's crossover networks
send bass-only signals to its built-in amplifier, allowing the subwoofer to add extra
bass to the output from your other speakers.
To simplify the instructions in this manual, the main speakers are referred to as the
“front speakers”. The AV receiver, stereo receiver, or integrated amplifier is referred
to as the “receiver.”
Warnings
We recommend that you not operate your speakers with the bass, treble, and loudness
controls set to full boost. This will place undue strain on the electronics and speakers
and could damage them.
The volume control setting on your 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.
Whenever changing cables or pulling plugs, ALWAYS TURN OFF ALL EQUIPMENT. This prevents transients from entering the speakers and prevents electrical energy from reaching you.
Keep all connections out of the reach of children.

Surround System Configuration
The optimum listening position is at the tip of the “stereo triangle.” The equilibrium
between the right and left stereo channels is best in this position, providing the most
balanced and realistic sound reproduction. Your AR speakers will operate most efficiently when located in parts of the room with “hard” acoustics, i.e., areas including
hard, smooth surfaces such as walls and wooden furniture. The speakers should radiate
the sound from this hard area into the “softer” parts of the room containing sound-absorbing elements such as upholstered furniture, carpets and so on. Try to avoid placing
sound-absorbing obstacles between the speakers and your listening position, as this
will muffle the sound and impair your listening pleasure. Your HT60 Series speakers
are fully shielded for use in audio/video applications. This allows you to place any of
the speakers next to the television without affecting picture quality. If you are using
other speakers, be sure to locate them at least 3 feet from the television to avoid interference to the set’s picture. Installing the speakers at least 1 foot away from the side
walls will prevent exaggerated “booming” bass and produce more balanced, detailed
sound reproduction. If possible, the speakers should be installed with the tweeters on
the same level as the listener's ears. If you install the speakers in a wall unit, make sure
the fronts of the speakers are flush with the front of the wall unit. Rear speakers should
be placed approx at ear level or slightly higher. The center channel speaker should be
placed above or below the television.

Connecting the Subwoofer
IMPORTANT: To avoid damaging your equipment, make sure the subwoofer
and all components are turned off before making any connections.
Subwoofer Placement
Placement of your subwoofer will dramatically affect its performance. Your AR subwoofer is designed to work best when placed on the floor within 15 feet of your front
speakers. For detailed accurate bass response, place your subwoofer near a wall, but
away from a corner. If you prefer fuller, more accentuated bass, try placing your subwoofer directly in a corner. This will substantially increase bass response. When possible, place the subwoofer close to your system's front speakers to keep wire or cable
runs short. See “Surround System Configuration” on page 5 for more information on
speaker placement.
Since low frequency sound is omni-directional, the subwoofer can be placed anywhere
in the room. Use the Low Pass Frequency control and the Phase switch to adjust the
output. Use the subwoofer's Level control to adjust the volume relative to the placement (this may require resetting the subwoofer's polarity switch). See “Subwoofer/
Preamp Controls & Connections” on page 7 for details on adjusting these settings.
Connecting the Subwoofer Line-In
Connect an audio cable from the Subwoofer output on your receiver to the Line-In inputs on the subwoofer. Note that the subwoofer has a left and right input, allowing it
to receive stereo bass signals. If your receiver has only one output, you can run a single
audio cable into either the left or right input on the subwoofer. Another option is to use
a “Y” cable to connect both the left and right inputs on the subwoofer.
Connecting the Speaker Level (High Level) Inputs
For older receivers with no LFE or Subwoofer outputs, run speaker wire from your receiver's front left and right speaker level outputs to the left and right speaker level inputs on the subwoofer. Connect the front left and right surround speakers in parallel
with the subwoofer.
NOTE: To avoid possible output problems, do NOT use the "speakers B" output to attach the subwoofer to a receiver.
IMPORTANT: All speakers in a system must be connected with the same polarity. Polarity is indicated by a color stripe on the insulation, by ridges molded into the insulation, or by the colors of the wire - one copper and one silver.
Strip the insulation from the speaker wire ends to reveal the bare conductors
before connecting to a speaker, subwoofer or receiver. Always connect the red
(+) terminal on the receiver to the red (+) terminal on the Subwoofer, and connect the black (-) terminal on the receiver to the black (-) terminal on the Subwoofer. The same is true for hooking up the Receiver outputs to the Front
speakers: red (+) to red and black (-) to black.

Subwoofer/Preamp Controls & Connections
The amplifier and subwoofer controls are located on the back of the subwoofer cabinet,
shown in Figure 3.
FIGURE 3 - Subwoofer/Preamp Controls & Connections

HT60.book Page 8 Monday, April 2, 2007 6:28 PM
• Power cord: Plug the power cord into an AC wall outlet.
• MODE (AUTO ON/OFF): Move this switch to turn the AC supply OFF/
ON. When AUTO ON is selected, the Subwoofer remains in the stand-by
mode until an audio signal is detected. (During standby mode, the front
LED indicator remains un-lit, while the rear indicator is illuminated red.)
After a few minutes without an audio signal, the Subwoofer automatically
reverts to stand-by mode.
• SUB/LFE: Move this switch to select LFE or SUB (normal subwoofer)
mode. Select LFE mode if you are using your receiver’s LFE output.
• POWER: The green LED POWER indicator on the front illuminates blue
and the LED indicator on the back illuminates green when the amplifier is
turned on.
• Fuse: The 250v 2.0A (AGC Type) is located on the amplifier panel on the
back of the Subwoofer cabinet under the power cord. This fuse protects
against internal and external faults. If the Power switch is ON but the
power indicator LED remains unlit, the fuse should be replaced. T o replace
the fuse, unplug the power cord from the AC outlet, then unscrew the
center piece and replace the fuse.
IMPORTANT: If the fuse is blown, replace it ONLY with a fuse of the
same type and current rating (250v 2.0A). Severe damage or fire could
result from improper fuse replacement.
• SPEAKER LEVEL IN/OUT (L and R): These terminals are used for making connections with speaker wire.
• LINE LEVEL IN/OUT (L and R): These connections are used for bass
audio signals.
• CROSSOVER FREQUENCY: Adjust the system’s tonal balance by setting the upper frequency limit (40Hz-180Hz) for the audio signals going to
the subwoofer.
• SUBWOOFER LEVEL: Bal ance the loudness (OFF, or -30dB to +9dB) of
the subwoofer relative to the front speakers and compensate for room
effects on the subwoofer .
• PHASE: Contro l th e ph ase o f th e subwoofer relative to the front speakers.
To determine the appropriate phase setting, select either regular (0°) or
inverted (180°) and perform a sound test. Listen carefully to the sound
quality while playing a CD with low bass such as percussion or bass lines,
then select the position that produces the fullest and most dynamic bass.
You may need to adjust the LEVEL control (volume) and the CROSSOVER FREQUENCY control after setting the PHASE switch.

Installing your Surround Speakers
The surround speakers are identical and can be used for any channel.
Surround Speaker Placement
Speaker placement is critical, and can make the difference between good and great
sound quality. For optimum sound quality, position your front (main) surround speakers slightly in front of the video screen and turn them slightly inward (towards the center of the listening area). This reduces the possibility of reflection from the video
screen or side walls. Turning the surround speakers farther inward produces a smaller
sound stage and focuses the sound more directly to the listener's ear. Turning them less
or not at all produces a larger sound stage and compromises localization of the sounds.
Placing the left and right surround speakers closer to the front wall, side walls, or corners will increase the amount of audible bass. The HT60 surround speakers are designed to be placed within 18 inches of a wall for optimum tonal balance. Rear
speakers should be placed approx at ear level or slightly higher. The center channel
speaker should be placed above or below the television. Based on your listening preferences, you will want to experiment with the placement of your surround speakers.
When possible, the surround speakers should be installed at the same level as the listener's ears. See “Surround System Configuration” on page 5 for more information on
speaker placement.
Connecting the Surround Speakers
Strip approximately 3/8" of the insulation from the speaker wire, exposing the bare
conductors. Twist each end of the speaker wire, and then connect the speakers in phase.
Connect the positive (+) terminal from the Receiver to the positive (+) terminal on the
speaker. Red typically indicates positive. Connect the negative (-) terminal from the
Receiver to the negative (-) terminal on the speaker. Black is typically the color code
for negative.
Wall Mounting
Your HT60 surround speakers can be mounted to the wall using the ¼-20 threaded insert located on the back of the speaker. This is designed for use with after-market
mounting hardware. See your local dealer for details.
