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.
