Setup Guide
rev 806
NHT's Classic Series represents our best efforts to date
in passive loudspeaker design. Classic starts with the
design fundamentals that have made NHT's reputation
for accuracy and high performance, and adds new driver
and cabinet technologies which reduce distortion and
improve dispersion. The benefit to you is a more
articulate, more musical listening experience.
Placement
NHT's Classic center channel designs are meant to be
placed horizontally. Ideally the center channel should be
placed immediately above or below the television, in as
close proximity as possible (Fig. 2).
All Classic Series models share a similar "voice" or
tonality so that you are assured a matched system no
matter which models you decide to add as you build your
system.
The following Setup Guide will help you unpack, connect
and place your new Classic loudspeakers in your
listening room. If you are interested in specifications or
the technology used in the design, please visit our website at www.nhthifi.com and look up information on your
specific model. If at any time during or after setup you
require assistance, feel free to call our Customer Hotline
at 1-800-NHT-9993 (800-648-9993).
The Absolute Center is designed as the matching center
channel loudspeaker for the NHT Absolute Zero. The
compact size is perfect for small to medium size rooms.
Fig. 2
The three front speakers in a home theater system
sound best when placed at the same distance and the
same height in relation to each other. In addition, try if
possible to have the tweeter height close to ear level
when sitting. In situations where the top face of your
television may be higher than ear level, you can use the
supplied "3rd foot" (Fig. 3) to aim the speaker at your
listening position.
Fig. 3
To use the "3rd foot", simply adjust the center channel to
the angle you desire and tighten the finger screws.
Try to position the front of the center channel to be even
with the front of the televison or shelf on which it is
placed. This eliminates undesirable reflections and
improves intelligibility of the speaker. This can be difficult
to achieve with some standard televisions that have
curved or angled tops. We have provided a rubber pad
on the lower end of the foot which will provide a stable
base for the back of the center channel in such
situations. Be sure you review safety and stability of the
center channel before considering setup complete.
Connections
Before connecting your Classic center channel to your
receiver/amplifier, turn off the AC power to avoid
potential damage to your components.
Take a look at the terminals on the back of your
speakers. They can accept raw wire, banana plugs or
spade lugs. Note that these terminals should be
tightened only by hand, as excess force can break them.
We recommend your speaker wire be at least 16 gauge.
Your NHT dealer can recommend the correct wire. Use
the same length of wire for each channel.
The best tool you have is your ears. If you hear
unusual distortion or breakup, decrease the volume
immediately. If you are unsure, place your hand close
the woofer. If you feel heat radiating from the driver, you
are playing the system beyond its limits.
Maintenance
Your NHT speakers will require little if any maintenance
under normal use. Try to avoid exposing them to direct,
sustained sunlight, high temperatures or moisture.
Cabinets can best be dusted using a clean, soft chamois
cloth. The finish on your speakers is durable but dry
rough cloth can leave fine scratches over time. Try to
avoid using liquid cleaners and household furniture
polish, particularly around the speaker components. To
clean grilles, remove them from the speaker and use a
soft brush or a vacuum on its lowest setting. Do not
attempt to clean the speaker components.
Satisfaction
We hope you enjoy the sound of your NHT Classic
speakers as much as we do. Your warranty is printed on
the back of this Setup Guide. Once again, if you have
any questions or problems, please call us at our
Consumer Hotline. 1-800-NHT-9993
Prepare the wires by stripping ¼" - 3/8" of insulation from
the ends and tightly twist the exposed strands.
Finally, connect your speakers to your amplifier or
receiver, making sure that the speakers are "in phase,”
that is, the same half of the wire pair connected to the
Positive terminal (+, usually red) on both the amplifier
and the speaker. The other half of the same wire
connected to the Negative (-, usually black) terminals on
both amplifier and speaker.
Most speaker wire has one half of the pair marked with
either lettering, ridges, the "+" sign or color to help you
make the proper connections.
Before powering up your receiver/amplifier, make sure
there are no stray strands from one terminal touching the
other terminals. Also, try to keep speaker wires from
laying across AC power cords.
Operation
All NHT Classic speakers are compatible with most
amplifier power ranges and are designed to handle a
wide range of listening levels. Every speaker, however,
has limits and it is important to listen for them. Speaker
damage most often occurs from sustained high volume
levels in some or all frequencies. Try to avoid excessive
bass or treble settings or equalizer boosts.
