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 12.
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 center, front left and front right
channels 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.
Page 15 shows the input and output
connections for biwiring a left front speaker
and a right front speaker.
Biwiring
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 10 and 11.
• Connect the rear speakers as shown
on pages 10 and 11.
Input connections
• Connect your preamplifier’s outputs to
the amplifier’s corresponding input
jacks. If your preamplifier has XLR
outputs, use these wherever possible.
