Biwiring
If your speakers can
be biwired or biamped,
they will have separate
input terminals for the
woofer section and the
upper range.
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.
Each channel of the Sunfire Amplifier has
two pairs of outputs. One idea is to use the
voltage source to drive the woofer, and the
current source to drive the upper range. This
will offer improved performance compared to
conventional wiring.
Stereo Biwire Connections
• Connect the amplifier’s right voltage
source output to the right speaker’s
woofer input terminals.
• Connect the amplifier’s right current
source output to the right speaker’s
upper range input terminals.
• Connect the amplifier’s left voltage
source output to the left speaker’s
woofer input terminals.
• Connect the amplifier’s left current
source output to the left speaker’s
upper range input terminals.
• Connect your preamplifier’s outputs to
the amplifier’s corresponding inputs.
