Yamaha AVENTAGE RX-A670 Owner's Manual

Using the four internal amplifiers for front speakers allows you to have more high-
quality sounds.
For example, you can use 2-way bi-amp speakers with a woofer and tweeter for front
speakers. It produces expansive sound in a bi-amp system featuring a woofer and
tweeter. By directly driving each speaker individually, it produces powerful sound
while maintaining the feeling of a high S/N ratio.

When using the four internal amplifiers in bi-amp system, the unit supports only 2- to 5.1-channel speaker
system.

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.94) in the “Setup” menu
to “BI-AMP” after connecting the power cable to an AC wall outlet.

▪ Surround back speakers, presence speakers, bi-amp speakers or Zone B speakers cannot be connected

simultaneously.

▪ The FRONT terminals and SURROUND BACK/PRESENCE/BI-AMP/ZONE B terminals output the same

signals.

▪ 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.
