If your speakers can be biwired or
biamped, they will have completely
separate input terminals for the woofer
sec tion and the upper range. See the
speak er diagram and dis cus sion on
page 12.
Make sure that any links be-
tween the woofer and upper
range posts are re moved
from the speakers when
you want to biamp or biwire them.
Consult your speak er owner’s
manual for details.
The front channels of the Cinema
Grand AmpliÞ er each have two pairs
of outputs which can be used to biwire
your speakers. The idea is to use the
voltage source to drive the woofer,
and the current source to drive the
upper range. This will offer improved
per for mance and still allow you to
connect Þ ve speakers for your home
theater system.
This page shows the input and out-
put connections for Biwiring a left front
speaker and a right front speaker.
Output connections
• Connect the ampliÞ er’s right
front voltage source output
to the right speak er’s woofer
input terminals and connect
the ampliÞ er’s right front cur-
rent source output to the right
speaker’s upper range input
terminals.
• Connect the ampliÞ er’s left
front voltage source output
to the left speaker’s woofer
input ter mi nals and connect
the ampliÞ er’s left front cur-
rent source output to the left
speaker’s upper range input
terminals.
Biwiring Connections
The center and rear speakers have
been omitted from this drawing for
clarity. If your center speaker can be
biamped, then connect it to the center
channel outputs in the same way as
shown above. Otherwise, connect it
and the rear speakers as shown on
pages 10 and 11.
Input connections
Connect your preampliÞ er’s outputs
to the ampliÞ er’s corresponding input
jacks. If your preampliÞ er has XLR
outputs, use these wherever possible.
