Thank you for your purchase of the NHT SuperZero minimonitor.
Please take a few minutes to read through this Owner's Manual
prior to installing your new speakers. The information provided will
help you to obtain maximum performance from your audio system.
If you have questions or need assistance at any time during the
installation or operation of your new speakers, please call your
NHT Dealer or our Toll-Free Customer Hotline at:

Please retain the SuperZero’s packaging to protect the speaker in the
event that you move or transport it.
Design
NHT loudspeakers are designed to deliver refined, musical sound from
attractive and affordable packages. Our efforts are guided by the study
of human hearing and are optimized for real-world use. Every NHT
speaker undergoes rigorous testing and quality control at the factory to
ensure you years of listening pleasure.
For over six years, the award-winning SuperZero has set the industry
standard for affordable minimonitor performance. Exemplifying the
concept of “less is more,” the SuperZero is designed with no
revolutionary technologies or fancy parts, just sensible electronic
topology and custom-designed drive units. It is this focused simplicity
and elegance of design that gives the SuperZero its astonishing
clarity and remarkable spaciousness.
An ideal choice for listeners with limited space, the SuperZero is ideally complemented by NHT’s SubOne powered subwoofer system for
seamless full-range performance. Magnetically shielded, the
SuperZero is equally at home in audiophile-quality stereo systems or
compact home theater systems.
Placement
The compact size of the SuperZero allows it to be placed on speaker
stands, mounted on walls, or on shelves. The SuperZero is designed
for indoor use only.
The SuperZeros should be placed as symmetrically as possible,
slightly toed-in, with the drivers facing the listening area without
obstruction from furniture. The tweeters should be at equal height and
at approximately ear level to ensure accurate response. If possible,
arrange the speakers so that the distance between the listener and the
center of the speaker plane is 1.5 times the distance between the two
speakers (fig.1). This configuration puts the listener in the center of the
stereo image.
The SuperZeros perform best when placed on rigid speaker stands,
approximately 29 inches high, situated at least 12 inches from the rear
wall (behind the speakers) and at least 30 inches from the side walls.
For smoothest response, the distance from the side walls should be
different than the distance from the rear wall. NHT offers matching
speaker stands (ZStand), available through authorized dealers, that
put the SuperZero at the proper listening height. Preferably, use
spikes or cones to firmly couple the speaker stand to the floor.
Additionally, the SuperZero is easily mounted to a wall, using the predrilled threaded insert centered on the back panel, just above the terminal cup. This 1/4” x 20 insert is designed to accommodate the readily available OmniMount STMP-25 series mounting bracket
(OmniMount Systems: 602-829-8000). Before attempting this installation, carefully evaluate the mounting surface, making sure that its composition and construction are strong enough to support the load safely. If you are unsure about the type or use of mounting hardware for
your installation, consult a professional contractor or a knowledgeable
hardware store.
The SuperZeros may also be placed on a shelf or in a cabinet,
however this placement may not yield the best sound. For best results,
place the speakers flush with the front, and not pushed back on the
shelf.
When using the SuperZeros in a five-channel home theater
configuration, it is ideal for all five speakers to be placed equidistant
from the listening position. When using a SuperZero as a center
channel speaker, it should be placed directly above or below the
television, as close to the screen as possible. It may be placed either
in the vertical or horizontal orientation. The SuperZero is magnetically
shielded and will not distort the picture’s color. If possible, all three
front speakers in a home theater system should be placed at equal
height and at ear level from the listening position. We recommended
using the NHT SuperCenter, which is tonally matched to the
SuperZero.
Experimentation is the key to finding the best arrangement in your
particular listening environment. Be patient, have fun, and remember
that small changes in speaker position can sometimes have a
significant effect on the sound. For example, moving the speakers
nearer to a room boundary (walls, corners) will tend to increase their
bass output, but may result in “boomy” or “muddy” sound. Conversely,
situating the speakers farther away from room boundaries will tend to
decrease their bass output, but may result in greater articulation and
better imaging.
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.
Connections
Before connecting speakers to your system, it is important that you
turn off the power to your amplifier / receiver to avoid damage to
the equipment.
The NHT SuperZero is compatible with virtually all quality amplifiers.
Proper wiring of the speakers is essential to good sound. At a minimum,
16AWG wire is recommended for runs of 10 feet or less, with heavier
special purpose speaker wire used for longer runs. For specialty wire
considerations, consult your local authorized NHT retailer. For best
results, use equal length runs of wire for the left and right speakers.
Prepare your speaker wire 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 both the left and right speakers "in-phase." That is,
the Positive (red) terminal on the amplifier output must be connected to the corresponding Positive (red) terminal on the speaker.
Likewise with the Negative (black) terminals. All speaker wires 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
fig. 1

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
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.
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 SuperZero 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 volume levels, more powerful amplifiers are preferable
because they are less likely to run out of power.
