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 HD510 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
Controls & Connections” on page 8 for details on adjusting these settings.
Connecting the LFE (Low Frequency Effects) Input
Connect a single audio cable from your receiver's LFE output into the Subwoofer LFE
input. This input bypasses the subwoofers internal crossover. When connected to the
LFE input on the subwoofer, you will have no control of the Low Pass Frequency Control (crossover). The “Large” position sends LFE signals to all speakers selected
“Large”. The “Small” position sends all bass to the LFE output directly into the subwoofer and no bass to the surround speakers. The “small” setting is recommended for
the HD510 speakers due to their size and low-frequency output. For setting the Small
and Large speakers parameters, please refer to your receivers bass management section
in the owners manual.
NOTE: The LFE channel is not a subwoofer channel. It carries low bass effects
to any speaker that can handle low frequency content through the receiver's
bass management controls. If you would like control of the crossover, you can
connect the LFE output from your receiver directly into the Line-In inputs of
the subwoofer.
Connecting the Subwoofer Line-In
If your receiver does not have LFE output, but has a subwoofer output, 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.
page 6
HD510
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 Controls & Connections
The amplifier for the subwoofer is located on the bottom of the subwoofer cabinet. The
speaker level inputs, line level inputs, LFE input and output, power switch, AC power
cord and fuse are located on the amplifier panel, shown below.
FIGURE 3 - Subwoofer Controls & Connections
• Power cord: Plug the power cord into an AC wall outlet.
• POWER (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. After a few minutes without an
audio signal the Subwoofer automatically goes into the stand-by mode.
The green LED indicator light, located above the Power switch, illuminates when the amplifier is turned on.
• Fuse: The 250v 1.6A (AGC Type) is located on the amplifier panel on the
bottom of the Subwoofer cabinet. 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. To replace the fuse, unplug the
power cord from the AC outlet, then unscrew the center piece and replace
the fuse.
page 8
HD510
IMPORTANT: If the fuse is blown, replace it ONLY with a fuse of the
same type and current rating (250v 1.6A). Severe damage or fire could
result from improper fuse replacement.
• SPEAKER LEVEL IN (L and R): These terminals are used for making
connections with speaker wire.
• LFE IN: LFE (Low Frequency Effects) inputs are used to carry additional
low-bass information from a Dolby Digital source. Use the 90° RCA adaptors (included) to connect the LFE output from the receiver.
• LFE OUT: This output is internally connected to the LFE input. Use the
90° RCA adaptors (included) to connect an additional AR subwoofer. The
type of connection is often called a “daisy chain.”
• LINE IN (L and R): These connections are used for bass audio signals
when an LFE input is not available. Use the 90° RCA adaptors (included)
for these connections.

Subwoofer Preamp Controls
The controls for the low pass frequency, level, and phase switch controls are located
under the removable panel on the front of the subwoofer's AR logo.
FIGURE 4 - Subwoofer Preamp Control Panel
Place your fingertips on the bottom edge of the panel and pull out to access these controls, shown below.
FIGURE 5 - Subwoofer Preamp Controls

HD510
• LOW PASS FREQUENCY control: Adjust the system’s tonal balance by
setting the upper frequency limit (50Hz-150Hz) for the audio signals going
to the subwoofer.
• LEVEL control: Balance the loudness (MIN to MAX) of the subwoofer
relative to the front speakers and compensate for room effects on the subwoofer.
• PHASE switch: Control the phase of the 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 LOW
PASS FREQUENCY control (crossover) 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 HD510 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
There are 2 mounting methods for the HD510 surround speakers. The first is 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. Another option is to
use the “J” shaped wall brackets included with the system. Determine the placement
for the speaker and mount the wall brackets securely to the wall. NOTE: Choose the
appropriate mounting fasteners (not included) for your wall to ensure a secure and stable installation.
NOTE: The rubber bump-ons can be used when the speakers will sit on a shelf.
These bump-ons will raise the speaker slightly, allowing it to sit level when the
wire management channel on the back of the speakers is used.

Using the Cover Switch
The switch located on the terminal cup of the surround speakers is designed to be used
with the AR Home Décor Series of decorative covers. Place the switch in the right position when using the surround speaker with a decorative cover. This equalizes the
tweeter to compensate for the covers. The speaker will sound slightly brighter without
the covers. Place the switch in the left position to equalize the tweeter for use without
the covers.
NOTE: See brochure or visit the AR website for additional details on the AR
Home Decor Covers.
