introduction
Congratulations, and thank you for purchasing an a/d/s/ Home Theatre speaker system. The HT-
series loudspeakers offer the perfect combination of style and performance for your Home
Theatre System. The design of the drivers and computer-optimized crossover networks result in
a smooth, flat frequency response, which in turn yields exceptional imaging and superb transient
impact. The bass response and acoustic output capabilities of your HT-series speakers are
remarkable for units of such compact dimension. a/d/s/ Home Theatre speakers are the ultimate
choice for your discerning taste and lifestyle.
Be sure to save your sales receipt. It is your best record of the date of purchase, which is required
for warranty service.
Read and follow all cautions, warnings and notes.
cautions
To reduce the risk of electric shock, do not remove any parts of the speaker. There are no user
serviceable parts inside. If service is required have it performed by a qualified service
professional.
WARNING!
To prevent fire or shock hazard, do not expose the speakers to rain or submerge in water. The
speakers should be situated away from heat sources such as radiators, heat registers, stoves or
other heat sources.
Be sure all the components in the system are turned off while making audio and power
connections.
WARNING! Mounting brackets must be attached to speaker cabinet exactly as shown. Failure to
follow these guidelines will result in the bracket to cabinet attachment failing, and
may result in injury or damage to property.

CORRECT WRONG
BRACKET
cabinet bracket installation
Your HT300 or HT400LCR bookshelf speakers are provided with a unique cabinet bracket assembly that
allows the speaker to be mounted using universal or custom-fabricated brackets. Because of the weight
of the HT300/400LCR, these cabinet brackets must be installed carefully and according to the supplied
instructions and diagrams in order prevent risk of personal injury or property damage. Please study the
diagram showing the correct orientation for the cabinet brackets prior to beginning the assembly and
mounting process.
Note: the cabinet brackets only work correctly when installed as shown. Failure to install the
cabinet bracket correctly may result in the speaker cabinet falling.
Determine the correct location for the cabinet bracket on the rear cabinet surface that is required for the
specific installation.
Note: it is generally better to keep the bracket located more towards the center of the cabinet
as the suspended weight is more evenly distributed.
Insert the bolt or other mounting hardware that will be used to fasten the cabinet bracket to the
mounting bracket or arm. Make sure the bolt or securing hardware is tightened prior to placing the
cabinet bracket in place against the rear panel of the HT speaker cabinet. Secure the bracket to the
cabinet as shown using the supplied set screws, making sure the bracket rotates completely under the
slotted edge of the rear cabinet.
Note: the set screws must line up and engage the small slot on either vertical side of the rear
cabinet panel. Failure to properly locate the bracket and secure these screws correctly may
cause the cabinet bracket assembly to separate from the cabinet, allowing it to fall.
Once the bracket and set screws are properly positioned, tighten the set screws to lock the bracket in
position. Make sure the set screws stay locked in the cabinet grooves as they are tightened.
speaker placement
Where you locate the speakers in the room plays a vital role in the sound quality you will enjoy.
Since every room is a little different, you should experiment with various locations to see which
gives the best sound in your particular application. Here are some general guidelines to help you
select appropriate locations
In general, your speakers will have the smoothest response and best imaging when located at
least two to four feet from the back and side walls in the listening room. Moving a speaker closer
to one or more of the boundaries will increase the bass output. In some rooms, the extra bass
may sound good while in others it may cause the bass to sound too strong.
Hard surfaces near a speaker can affect the distribution of high frequencies. Think of a hard wall
as if it is a mirror. Just as a mirror will reflect a nearby object so that you see a second "virtual"
object, a hard wall will reflect sound so that you hear a second "virtual" source of the sound. If
the reflected sound is strong enough it will confuse the imaging of the system. If the speakers
are placed near side walls, try toeing the speakers towards the center of the room. Drapes or
cloth hangings on nearby walls will help to cut down undesired reflections. Drapes are
particularly helpful if the speaker is adjacent to windows or glass doors.
center channel
The HT400LCR when positioned on its side, and placed in the optional HT base, functions as an
accurate and exceptional center channel speaker. The HT400LCR may be placed either above or
below the video monitor when using a direct view or rear projection set. The base of the HT
series allows the speaker to be tilted up or down, simply place the speaker on the base in the
desired orientation. The HT400LCR may also be used without the base by positioning it vertically,
which is the recommended orientation for optimum horizontal dispersion. With front projection
video monitors, the center channel is commonly placed below the screen. Alternatively, by using
an acoustically transparent perforated screen it may be placed in a vertical orientation, directly
behind the screen for optimum imaging.

main speaker separation
A good rule of thumb is to start by arranging your preferred listening position and the left and
right speakers positions, such that they represent the points of an equilateral triangle. You
should then experiment by varying the separation and the horizontal angle of the speakers until
you reach the sonic sound stage that you prefer.
Although all of the HT series speakers are video shielded, placing them next to a TV monitor will
not typically give adequate separation. When possible, move the speakers a few feet away from
either side of the monitor. Also, when the center channel speaker is used, the left and right
speakers should be located so they are approximately the same distance from the listening
position as the center channel. If they are too far forward, you will lose integrity of the center
image. If they are too far away, separation and image width will suffer.
connections
wire
Use two-conductor stranded-type, insulated wire to connect the speakers to the amplifier. There
are many types of high performance wire available for speaker connection. Your a/d/s/ retail
dealer can recommend appropriate wire. If you want, standard "lamp" wire or "zip cord" can
be used. Use 16 gauge for runs less than 50 feet, and use 14 gauge or larger, for longer runs.
Using wire smaller than 16 gauge is not recommended.
connecting the speakers
The HT series have color-coded spring loaded input terminals. Pressing the spring loaded
terminals expose holes in the post. Insert stripped or terminated wires into the exposed hole.
Release the terminals to clamp the wire into place.
polarity
The polarity (the positive/negative orientation of the connections) for every speaker-to-wire and
wire-to-amplifier connection must be the same so that the speakers will be "in phase". If the
polarity of one connection is reversed, bass output is reduced and stereo imaging is degraded.
High frequency level switch
The high frequency level switch alters the amplitude of the frequency band from 2kHz to 20kHz.
• High (up) position on the frequency level switch gives a 3dB boost in the high frequency band.
• Low (down) position on the frequency level switch results in a flat frequency response.
Although this switch allows you to adjust for personal preference, a/d/s/ recommends that the
low position be utilized for systems that do not contain a subwoofer.

troubleshooting
Most difficulties with high fidelity equipment result from loose connections, bad
connecting cables or improperly set switches.
No sound It is rare for a speaker to fail completely. When there is no
sound, check all the speaker wire connections and
electronic equipment settings.
Dull or muted sound Operating the speakers at an unsafe power level can
damage the speakers. Take the speakers to your retail
dealer or an authorized service agency.
Distorted sound Distortion at moderate levels can be caused by loose
connections or stray wire strands shorting out an adjacent
wire at the amplifier or speaker terminals. If you hear
distortion or any type of buzzing or rattling sound from an
individual driver, contact your a/d/s/ dealer.
Noise or hum Continuous noise or hum are always from the electronic
equipment and not from the speakers.
