CHAPTER 2
Biamping connections
If your speakers can be biamped,
they will have separate input posts for
the woofer and the tweeter sections.
This diagram shows how to cre-
ate a very ef
Þ
cient system with an
active external crossover. The cross-
over will split the incoming preamp
signal into two frequency ranges: one
above and one below the cross over
frequency.
True biamping is very ef
Þ
cient
because each ampli
Þ
er channel only
receives and ampli
Þ
es the range
required for its driver. For example, in
the diagram below, the right channel
only am pli
Þ
es the low frequencies,
and the left channel only ampli
Þ
es the
high frequencies.
Make sure that you adjust the
crossover frequency to suit your

An alternative connection method
is to have one ampli
Þ
er running the
two woofers and the other running the
two tweeters. This is useful if your am-
pli
Þ
ers have different power ratings.
Use the more powerful ampli
Þ
er to run
the woofers.
