Biamping connections
This diagram shows how to create a very
efficient system with an external active
crossover. The crossover will split your
incoming preamp signal into two frequency
ranges: one above and one below the cross-
over frequency.
True biamping is very efficient because
each amplifier channel only receives and
amplifies the range required for its driver. For
example, in the diagram below, the right
channel only amplifies the low frequencies,
and the left channel only amplifies the high
frequencies.
Make sure that you adjust the crossover
frequency to suit your speakers. Check the
speaker’s specifications.
An alternative connection method is to
have one amplifier running the two woofers
and the other running the two tweeters. This is
useful if your amplifiers have different power
ratings. Use the more powerful amplifier to
run the woofers.
