The loudspeakers have two sets of 
bind ing 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 
re moved from the loudspeakers 
when you want to biamp or biwire 

them. If not, this may cause damage to 
your amplifi er..

In a biamp system, each loudspeaker 
can be driven by two separate amplifi er 
channels; one to drive the woofers and 
one to drive the ribbon. 

Biamping with a Sunfi re     
Theater Grand Amplifi er 

The front channels of Sunfi re's Theater 
Grand Amplifi ers 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 amplifi er’s right rear 

output to the right loudspeaker’s 
woofer input terminals. Connect the 
amplifi er’s right front current source 
output to the ribbon input terminals. 

•      Both amplifi er channels are fed with 

the same (right, front) line-level 
signal from your preamp.

Conventional Biamping

If you are not using a Sunfi re Theater 
Grand Series amplifi er (or you are 
using the current source outputs for 
something else), then connect sepa-
rate amplifi er channels to the woofer 
terminals and ribbon terminals. The 
amplifi ers should be of identical power 
output and performance. Both amplifi er 
channels are fed with the same line-
level signal from your preamp.
