Playing back more high-quality sounds with bi-amp connections
Using the four internal amplifiers for front speakers allows you to have more high-
quality sounds.
For example, you can use 2-way bi-amplified speakers with a woofer and tweeter for
front speakers. It produces expansive sound in bi-amp system featuring a woofer and
tweeter. By directly driving each speaker individually, it produces powerful sound
while maintaining the feeling of high S/N ratio.
Note
When using the four internal amplifiers in bi-amp system, the unit supports only 2- to 5.1-channel speaker
system.
Connecting front speakers that support bi-amp
connections
When using front speakers that support bi-amp connections, connect them to the
FRONT terminals and SURROUND BACK/PRESENCE/BI-AMP/ZONE B
terminals.
To enable the bi-amp function, set “Power Amp Assign” (p.85) in the “Setup” menu
to “BI-AMP” after connecting the power cable to an AC wall outlet.

Note
Surround back speakers, presence speakers or Zone B speakers cannot be used during bi-amp
connections.
The FRONT terminals and SURROUND BACK/PRESENCE/BI-AMP/ZONE B terminals output the same
signals.
Notice
Before making bi-amp connections, remove any brackets or cables that connect a woofer with a
tweeter. Refer to the instruction manual of the speakers for details. If you are not making bi-amp
connections, make sure that the brackets or cables are connected before connecting the speaker
cables.
