Sunfire CRW-3 - Manual (Page 16)

In a biwired system, each loudspeaker
is driven by one amplifier channel, but
separate speaker wire pairs are used
for the woofer and ribbon connections.
Make sure the bridge clips be-
tween the woofer and ribbon posts
are removed from the loudspeak-
ers when you want to biamp or
biwire them. If not, this may cause
damage to the amplifier.
Biwiring with a Sunfire
Theater Grand Amplifier
The front channels of Sunfire's Theater
Grand Amplifiers each have two pairs
of outputs that can be used to biwire
your speakers. The idea is to use the
voltage source to drive the woofers,
and the current source to drive the
ribbon. This provides the warmth and
openness of a tube amplifier section,
with the low end punch of Class A/B.
Combining the CRW speakers with a
Sunfire home theater amplifier, you get
the best of both worlds - a system that
is at the top of its class in musicality,
yet is still able to produce the visceral
dynamics required of the finest home
theater systems.
This example shows the connections
for biwiring a right front speaker.
Biwiring
• Connect the amplifier’s right
front voltage source output to the
right loudspeaker’s woofer input
terminals. Use a separate pair
of speaker cables to connect the
amplifier’s right front current source
output to the ribbon input terminals.
Conventional Biwiring
The example below shows the connec-
tions for biwiring a right front speaker
from a single output binding post pair.
• Connect the amplifier terminals to
the loudspeaker's woofer input ter-
minals, and use a separate speaker
cable pair to connect the amplifier
terminals to the ribbon input termi-
nals.
