■ 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. Example of a bi-wiring connection (L channel) ■ Connecting the power cable Plug the power cable into the AC IN inlet when all connections are complete, and then plug in the power cable to the AC outlet.
