Bi-wiring Connection

Bi-wiring provides improved bass and treble performance. Using terminals of both SPEAKERS A and SPEAKERS B, it separates high frequency from low frequency signals.

Important:

•Bi-wiring can be used only with speakers that support bi-wiring. Refer to your speaker manual.

•When making the bi-wiring connections, be sure to remove the jumper bars that link the speakers’ tweeter (high) and woofer (low) terminals.

•When making the bi-wiring connections, set SPEAKERS to A+B (➔ page 27).

Tip

•As shown on the illustration, the wiring terminals of SPEAKERS A are connected to the woofer and SPEAKERS B are connected to the tweeter. However, wiring them the other way around is also possible.
