SINGLE WIRE CONNECTION

Please take note of the jumper clips installed under the binding posts. These clips attach the high-frequency and low-frequency sections of the crossover together. Leaving these in place, connect the (+) wire from your amplifier to either red (+) binding post and the (–) wire from your amplifier to either black (–) binding post (Fig. 1).

WARNING! Only after jumper

clips are removed may you connect individual runs of speaker cable from your amplifiers to the high-fre-

quency and low-frequency signal input binding posts. Damage will occur to your amplifiers if the jumper clips are not removed.

BI-WIRE CONNECTION

This connection method replaces the jumper clips installed under the binding posts with individual runs of speaker wire from your amplifier. This doubles the signal carrying conductors from the amplifier to

the speaker, thus direct-coupling each portion of the crossover to the amplifier.

To bi-wire you must first loosen the binding posts and remove the jumper clips. Connect one set of wires to the upper set of binding posts which con- nect to the high-frequency drivers. Then connect a second set of wires to the lower binding posts which connect to the low-frequency drivers. Next, connect both sets of wires to the appropriate termi- nals on your amplifier. Please take care to connect both (+) wires to the (+) amplifier terminals and both

(–)wires to the (–) amplifier terminals. This is known as a parallel connection (Fig. 2).

PASSIVE BI-AMPLIFICATION

For those that desire ultimate performance, these speakers may be passively bi-amplified using the existing internal passive crossover elements.

This method takes the bi-wiring concept one step further. You will have a dedicated channel of
