Bi-amping your speakers

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.
• Connect your speakers as shown below.
This illustration below shows the connections for bi-
amping your front left speaker. Hook up your bi-amp
compatible speakers for other channels in the same way.

• Make sure that the + / – connections are properly
inserted.
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

The reasons for bi-wiring are basically the same as bi-
amping, but additionally, interference effects within the
wire could be reduced, producing better sound. Again, to
do this your speakers must be bi-wireable (that is they
must have separate terminals for the high and low
frequencies).
• To bi-wire a speaker, connect two speaker cords to
the speaker terminal on the receiver.
Using a banana plug for the second connection is
recommended.
Caution
• Make sure you use a parallel (not series, which are
fairly uncommon) connection when bi-wiring your
speakers.
• Don't connect different speakers from the same
terminal in this way.
