Bi-amping 

 

Bi-amping improves the way your sound system handles 
those more demanding moments when listening to music 
or watching cinema. When a piece of music is at its 
most demanding, bi-amping can help each section of 
your speaker by giving each driver and tweeter their 
own source of power, creating a sense that the sound 
being reproduced is more effortless, less constrained.

CAUTION:

 

You must remove the jumper strips that con-

nect the terminals before you bi-amp your loudspeakers; 
you will damage your loudspeakers if you don’t.

after removing the jumpers, connect the speaker wires 
from the high frequency amplifier outputs to the upper 
set (tweeter) of terminal posts on each speaker. follow 
the same procedure for connecting the low/mid  
frequency amplifier outputs (midrange/subwoofer) 
to the lower set of terminals. maintain correct wiring 
polarity (+ to +, – to –) in all connections.
