The loudspeakers have two sets of
binding posts that can be used for
biwiring or biamping. These posts
are joined with bridge clips for normal
operation.
Make sure the bridge clips are
removed from the loudspeakers
when you want to biamp or biwire
them. If not, this may cause damage to
your amplifier.
In a biamp system, each loudspeaker
can be driven by two separate amplifier
channels; one to drive the woofers and
one to drive the ribbon.
Biamping with a Sunfire
Theater Grand Amplifier
The front channels of Sunfire's Theater
Grand Amplifiers each have two pairs
of outputs. In a biamp system, use the
current source to drive the ribbon and
a separate channel's voltage source
to drive the woofers.
This example shows the connections
for biamping a right front speaker.
Biamping
• Connect the amplifier’s right back
output to the right loudspeaker’s
woofer input terminals. Connect the
amplifier’s right front current source
output to the ribbon input terminals.
• Both amplifier channels are fed with
the same (right, front) line-level
signal from your preamp.
Conventional Biamping
If you are not using a Sunfire Theater
Grand Series amplifier (or you are
using the current source outputs for
something else), then connect sepa-
rate amplifier channels to the woofer
terminals and ribbon terminals. The
amplifiers should be of identical power
output and performance. Both amplifier
channels are fed with the same line-
level signal from your preamp.
