Connect
2.1-channel connection Bi-Amp connection
You can use the front speakers via the 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.
To use the bi-amp connection for the front speakers, select "Amp Assign" and set "Assign Mode" to
"Bi-AMP" using steps 3 and 4 of "Set up "Amp Assign"" (vpage 63).

F.HEIGHT/AMP ASSIGN speaker terminals using the "Amp Assign" – "Assign Sp." settings (vpage 95).
To perform multichannel playback, connect the center, surround, surround back, and front speakers, and
subwoofer.
NOTE
• Use speakers compatible with bi-amp connections.
• When making bi-amp connections, be sure to remove the short-circuiting plate or wire between the
speaker's woofer and tweeter terminals.
