Bi-amp connection
A bi-amp connection is to connect separate amplifiers to the tweeter terminals and woofer terminals of
speakers compatible with the bi-amp function. This prevents the back electromotive force (returned force
without output) of the woofer sent to the tweeter, which affects the sound quality of the tweeter, and you
can enjoy playback with higher-quality sound.
In this case, set "Assign Mode" to "7.1ch(Bi-Amp)" or "5.1ch(Bi-Amp) + ZONE2" in steps 3 to 5 for "Set
up "Amp Assign"" (vpage 99).
NOTE
• For speaker cable connections, see page 93.
• For speaker impedance , see page 93.
• When making bi-amp connections, be sure to remove the short-circuiting plate or wire between the
speaker's woofer and tweeter terminals.
When using a front wide speaker, you can use the connectors on the
diagram to make a bi-amplifier connection. To make connections for these connectors, set
"Main Speakers" (vpage 100).
