set, use a "Y" splitter to send your two amplifiers
identical signals.
2) Sending identical amplified signals to your speakers:
To ensure that your amplifiers send out tone-and-level
matched signals to the ST4's, use either two identical
amplifiers, or two amplifier models of similar sound. If
two different models, make sure that at least one ampli-
fier has a volume control for level matching. If using an
audio / video receiver, use its left and right speaker out-
puts to drive the upper section, and a separate amplifier
to drive the subwoofer section.
3) Ensuring proper connections to the ST4's two sections:
It is very important, when bi-amplifying, to remove the
ST4's jumper straps, or you will damage your amplifiers!
Also, as in standard connection procedure, turn off all
preamplifier and amplifier power before connecting your
speakers. After doing so, connect one amplifier's output
speaker wires to the top set of ST4 binding posts and
one set to the bottom set, hand-tighten the posts, and as
in standard mode, separate the speaker cables from
others.
Some audio enthusiasts also believe that bi-wiring -- ie,
connecting two separate pairs of speaker wire, from the
two sets of speaker output terminals that many amplifiers
provide, to each set of speaker binding posts -- can bring
about improvements in sound. To bi-wire the ST4's, first
remove the metal jumper strap, and connect.

Operation
The NHT ST4 is compatible with virtually all quality
amplifiers, and is designed to handle a wide range of
listening levels.
Every speaker, however, has limits, and it's important to
listen for them. Speaker damage most often results not
from brief loud musical peaks, but from sustained high
volume levels in some or all frequencies. For this
reason, extreme volume settings and excessive bass,
treble or equalizer boosts are not recommended. If you
hear unusual distortion or breakup, or notice heat
coming from either your woofer or tweeter, decrease
volume immediately, neutralize any excess bass, treble
or equalizer boosts, and avoid setting any controls to
similar extremes again.
Maintenance
Your speaker requires no or minimal maintenance under
normal use, as long as you avoid exposing it to direct
sunlight, high temperatures, or moisture. Clean cabinet,
when necessary, using a damp cloth or a mild, non-abra-
sive cleaner; to clean grille, remove from speaker and
use a soft brush or a vacuum on its lowest setting. Do
not attempt to clean the actual drivers.
