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.
