Biamping with an external
crossover
If you have an external active
crossover, you can greatly increase
the effi ciency of your system. The
crossover will split the preamplifi er
output signals into two frequency
ranges.
You can connect the crossover's
low frequency outputs to the ampli-
fi er's rear channel inputs, and the
crossover's higher frequency outputs
to the amplifi er's front channel inputs.
This is an effi cient system because
the channels only amplify signals with-
in the frequency range of the speaker
el e ment they are driving. Little power
is wasted.
Make sure that the cross over point
of your active crossover is adjusted
to match the crossover point of your
speakers. Consult your speaker and
crossover owner's manuals.
