User's Manual
If your speakers can be biwired or
biamped, they will have completely separate
input terminals for the woofer section and the
upper range. See the speaker diagram and
discussion on page 16.
Make sure that any links
between the woofer and upper
range posts are removed from the
speakers when you want to biamp or biwire
them. Consult your speaker owner’s manual
for details.
The front channels of the Cinema Grand
Amplifier 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 perfor-
mance and still allow you to connect five
speakers for your home theater system.

connections for Biwiring a left front speaker
and a right front speaker.

System Configurations
Output connections
• Connect the amplifier’s right front
voltage source output to the right
speaker’s woofer input terminals and
connect the amplifier’s right front
current source output to the right
speaker’s upper range input terminals.
• Connect the amplifier’s left front
voltage source output to the left
speaker’s woofer input terminals and
connect the amplifier’s left front
current source output to the left
speaker’s upper range input terminals.
• If your center speaker can be
biamped, then connect it to the center
channel outputs in the same way as
above. Otherwise, connect it as shown
on pages 14 and 15.
• Connect the rear speakers as shown
on pages 14 and 15.
Input connections
• Connect your preamplifier’s outputs to
the amplifier’s corresponding input
jacks. If your preamplifier has XLR
outputs, use these wherever possible.
