In a biwire system, each loudspeaker 
is driven by one amplifi er 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 re moved from the loudspeak-
ers when you want to biamp or 

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

Biwiring 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 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 will offer improved per for -
mance.

This example shows the connections 
for biwiring a right front speaker.

Biwiring

•      Connect the amplifi er’s right 

front voltage source output to the 
right loudspeak er’s woofer input 
terminals. Use a separate pair 
of speaker cables to connect the 
amplifi er’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 amplifi er terminals to 

the loudspeaker's woofer input ter-
minals, and use a separate speaker 
cable pair to connect the same 
amplifi er terminals to the ribbon 
input terminals.
