NHT four 安装指导

Place the center channel speaker right above or 

below the TV

Place the rear speakers in an equilateral triangle 

with the listening position, at least 5' apart.

Rear speakers should be at the same height, or 

higher than, the front channels.

Obviously many rooms will not allow ideal placement.  As
a general rule, try to keep the rear channel speakers
equidistant from the center of the listening area.  If the
rear speakers have to be close to the main seating area,
add time delay to them in your surround processor to
make them seem farther away, and make sure they are
placed high, above the heads of the listeners.

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.

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
connect 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.

On the back of the Four, you will find two sets of binding
posts (Fig.5) and a metal jumper strap connecting them.
If you are not planning on bi-amping your Four system,
connect the speaker wires to the + and - terminals on the
top, leaving the jumper strap connected.

If you choose to bi-amplify the system, you will need at
least one NHT A1 amplifier and the NHT X2 active
crossover.  One A1 amplifier will provide monaural bass
to the system, two A1 amplifiers can be used with one X2
crossover for stereo bass (one for each speaker).
Consult the manual included with your X2 for connection
methods and crossover settings.

Warning: When connecting more than one
amplifier to the Four, make absolutely sure that
the jumper straps are removed. Otherwise
sever damage to your amplifiers will result.

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.

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.

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.

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.
