Bi-amping is when you connect the high frequency driver
and low frequency driver of your speakers to different
amplifiers for better crossover performance. Your
speakers must be bi-ampable to do this (having separate
terminals for high and low) and the sound improvement
will depend on the kind of speakers you're using.
CAUTION
• Most speakers with both High and Low terminals
have two metal plates that connect the High to the
Low terminals. These must be removed when you are
bi-amping the speakers or you could severely
damage the amplifier. See your speaker manual for
more information.
• If your speakers have a removable crossover network,
make sure you do not remove it for bi-amping. Doing
so may damage your speakers.

Bi-wiring your speakers

Your speakers can also be bi-wired if they support bi-
amping.
• With these connections, the Speaker System setting
makes no difference.
To bi-wire a speaker, connect two speaker cords to
the speaker terminal on the receiver.
CAUTION
• Don't connect different speakers from the same
terminal in this way.
• When bi-wiring as well, heed the cautions for bi-
amping shown at the left.
