■ Bi-wire connection

The bi-wire connection separates the woofer from the

combined midrange and tweeter section. A bi-wire

compatible speaker has four binding post terminals. These

two sets of terminals allow the speaker to be split into two

independent sections. This split connects the mid and high

frequency drivers to one set of terminals and the low

frequency driver to the other pair.

Caution

To use the bi-wire connections, the impedance of each speaker

must be 8 Ω or higher.

Note

Remove the shorting bars or bridges to separate the LPF (low

pass filter) and HPF (high pass filter) crossovers.

To use the bi-wire connections, switch the SPEAKERS selector

to the A+B BI-WIRING position.

■ Connecting the power cable

Plug the power cable into the AC IN inlet when all

connections are complete, and then plug in the power
