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.
When using the AudioCenter-1 with the NHT Model 1.5 or 2.5i for L-R main speakers, be sure to wire the
AudioCenter-1 “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.
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 AudioCenter-1 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 speaker requires 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.
