FINISHING THE INSTALLATION

CONNECTING THE LOUDSPEAKER

1.The terminals on your loudspeaker support Bi-amp or Bi-wire connections as well as standard connections. Please choose your preferred method as described below in Figure 5 on page 8.

2.At each loudspeaker, route the wire to the input connectors, then separate the loudspeaker wire so that at least 2 inches of each conductor are free. Strip away 1/4 inch of insulation from each loudspeaker wire. Using correct polarity, connect the appropriate conductor to each five-way binding post.

NOTE: OBSERVE CORRECT POLARITY: POSITIVE

(+)GOES TO THE RED POST AND NEGATIVE (–) GOES TO THE BLACK POST. IF YOU ARE UNSURE OF WIRE POLARITY, SEE THE SECTION, CHECKING LOUDSPEAKER PHASE BELOW.

wires to the terminals.

3.Connect the other end of the loudspeaker wires to the home theater receiver (or amplifier) in the same way.

4.Turn on the home theater receiver and calibrate all loudspeakers in the system according to the receiver manufacturer’s instructions.

BI-WIRE AND BI-AMP CHOICES

Bi-Wiring

In a Bi-Wired confi guration, separate cables are connected from the amplifi er or receiver output terminals to the speaker input terminals for the tweeter/midrange section and the woofers. Be sure to remove the straps linking the two sets of input terminals on the speaker. Your amplifi er and your loudspeakers may be damaged if you do not remove the straps. This type of confi guration results in lower resistance between the amplifi er and speaker than a standard connection with the same gauge cable. Some listeners may prefer Bi-Wiring to a standard connection with lower gauge cable.

Bi-Amping

In a Bi-Amplifi ed system, the tweeter and midrange section are driven by a separate amplifi er than the woofer. Both amplifi ers are connected to the same preamplifi er output. Use the same model amplifi er for the tweeter and woofer inputs and be sure to remove the straps linking the two sets of input terminals on the speaker. Your amplifi ers and your loudspeakers may be damaged if you do not remove the straps.
