Experimentation is the key to finding the best arrangement in your listening environment. Be patient, have fun, and remember that small
changes in speaker position can sometimes have a significant effect on the sound. In addition, room furnishings play an important role
in absorbing and reflecting soundwaves. Midrange and high frequencies in particular will be absorbed by soft furnishings such as sofas,
carpets and curtains. A large number of these soft furnishings will dull the sound, while a “live” room with few furnishings will brighten
the sound. If you are willing to spend some time fine-tuning the performance of your system, you will enjoy the benefits for years to
come.

Wall Mount Bracket
Tools you will need:
power drill with 1/8-inch bit
Philips screwdriver or power screwdriver
studfinder
Parts List (per speaker):
2 screws (#10 x 2” pan head)
4 foam isolation pads
1 template (included with owner’s manual)
level
Note: Whenever an object is affixed to a wall, you must take special care to mount it securely, to prevent it from falling and
causing possible injury. THE HDP-2 MOUNTING BRACKET MUST BE ATTACHED TO STUDS, AS DRYWALL (SHEETROCK)
ALONE CANNOT PROVIDE ADEQUATE SUPPORT. Make sure that the mounting bracket will not interfere with electrical wiring,
plumbing, etc. IF YOU ARE UNSURE ABOUT THE INSTALLATION OF THIS MOUNTING BRACKET, CONSULT A PROFESSION-
AL CONTRACTOR. Follow the mounting instructions carefully to ensure proper installation.
1. Begin by selecting the desired area on the wall where the HDP-2 will be mounted, preferably at a minimum height of 6 feet. Using a studfind-
er (or the old-fashioned “knocking” method), locate two adjacent studs, spaced 16 inches apart.
2. Using the supplied mounting template, mark the two screw locations, 16 inches apart and centered on the studs (Fig. 2). Use the level to
ensure that the screw locations are lined up precisely.
3. Drill a 1/8-inch pilot hole into the wall for each screw. Be sure that the hole passes through the drywall and into the stud. If the hole does not
reach a stud, re-position the screws and pilot holes until it does.
4. Insert one screw into each pilot hole. Screw all the way into the wall, until the screw head rests on the wall surface.
5. Loosen the screw 1 to 2 turns, so the bracket is able to slide down and the screw head will rest in the narrow section of the keyhole. The wall
screws are now properly set.
6. Attach the four foam isolation pads to the back corners of the HDP-2 by peeling the backing paper and adhering them to the speaker surface
(Fig. 3). These will prevent audible vibrations of the HDP-2 against the wall surface.
7. Attach speaker cable to the HDP-2. When possible in new construction applications, run the cable inside the wall and have it come out direct-
ly behind the location of the HDP-2. If this is not possible, simply run the cable along the wall behind the HDP-2. The speaker cable must be
a maximum of 1/4-inch thickness to fit betwen the wall and the HDP-2..
8. Hold up the HDP-2 so that the top keyholes are aligned with the wall screws (Fig. 4). The other keyholes are not used for this product. Carefully
place the brackets over the screws so that the screw heads slide into the round sections of the keyholes. Slowly move the HDP-2 downward
until the bracket has locked over the screw. Ensure that both brackets are securely mounted to their screws.

Nothing is obstructing the speaker
The brackets are mounted on the speaker facing opposite directions
You are using the proper keyhole on both brackets
The wall screws are exactly 16 inches apart, centered on the studs
There is enough room between the screw head and the wall for the bracket to slide down.

Connections
Before connecting speakers to your system, it is very important that you turn off the power to your amplifier / receiver to avoid
damage to the equipment.
The HDP-2 is compatible with virtually all quality amplifiers. Proper wiring of the speaker is essential to good sound. At a minimum, 16 AWG
speaker cable is recommended for runs of 10 feet or less, with 14 AWG used for longer runs. For specialty cable considerations, consult your local
authorized NHT retailer. For best results, use equal length runs of cable for all the speakers. Prepare your speaker cable by stripping 1/4” to 3/8” of
insulation from the ends and twisting the exposed wire strands tightly. The five-way binding posts on the back of the speaker will accept raw wire,
banana plugs, or spade plugs. Tighten the binding posts by hand, as pliers can strip or break them.
Be sure to wire all the speakers “in-phase.” That is, the Positive (red) terminal on the amplifier output must be connected to the corre-
sponding Positive (red) terminal on the speaker. Likewise with the Negative (black) terminals. All speaker cables have some sort of
marking along one or both conductors to help you make the correct connections. Incorrect speaker phase is indicated by weak bass and the lack
of a well-defined stereo image.
To minimize noise pickup, segregate cables by function. Do not run low level signal cables parallel to power cables, speaker cables, or digital cables.
Also, do not run speaker cables or digital cables parallel to power cords or parallel to each other. If different types of cables are placed near each
other at some place in your system, separate them by the maximum practical distance and cross them at right angles where they meet. Do not twist
or tie AC power cords with speaker cables.

Operation
The HDP-2 was designed to handle a wide range of listening levels, but every speaker has limits. It is important to use common sense and listen
for signs of possible distress from the speakers. Underpowered amplifiers are most often the cause of speaker damage. For example, a 60-watt
amplifier runs out of power when called upon to produce more than 60 watts, and the resulting distortion can damage the speaker. If you tend to
listen at high voumes, more powerful amplifiers are preferable because they are less likely to run out of power.
Noticeable distortion or harsh breakup is an indication that either your amplifier or your speakers are running beyond their capacity, and the volume
should be decreased. If you can feel any heat emanating from the woofer or tweeter, reduce the level immediately. Speaker damage most often
occurs from sustained high volume levels, not from transient sounds or brief musical peaks. Excessive boosting of bass, treble or equalizer controls
can worsen the problem, and is not recommended.
„
Maintenance
Your speakers require minimal maintenance under normal use. The cabinet may be cleaned using a damp cloth or a mild, non-abrasive glass
cleaner. To clean the grille, first remove it from the speaker, then brush lightly with a soft brush or use a vacuum on its lowest setting. Do not expose
the speaker to direct sunlight, high temperatures, or moisture. Do not attempt to clean the actual drivers.
