Bi-amping 3.2
By using an active crossover, you can divide up the frequency
range into several bands. For example, in doing so you can split
a mono signal into upper-frequency and lower-frequency ranges.
These two signals can then be hooked up to the inputs of your
amp, so that channel 1 amplifies the lows and channel 2 ampli-
fies the highs (2-channel operation). The outputs are connected
to a 2-way speaker, whereby the output signal 1 drives the
woofer and output signal 2 runs the drivers. Of course, you can
use two separate speakers instead of a single 2-way speaker.
A stereo signal can also be split up analogous to the example
described above. However, to do that you need two 2-way
speakers or 4 separate speakers, two EUROPOWER amps and
an active 2-way stereo crossover. The BEHRINGER SUPER-X
PRO CX2310 is optimally suited for this task and offers
additionally a single mono-subwoofer output. By deploying a
third EP2000 amp (preferably in mono-bridged mode) and a
subwoofer, you have a perfect setup that adds a low-frequency
system to the stereo bi-amp application (see fig. 3.7). The amp’s
input filters for the high/mid-frequency ranges should in this
case be engaged and set at 50 Hz. To remove low, disturbing
frequencies from the signal, the input filter for the subwoofer
signal should be set at 30 Hz.
The BEHRINGER EUROLIVE SERIES loudspeakers are an
outstanding solution for expanding your P.A. system, because
each frequency range/application has a speaker type that
optimally suits its characteristics.
Extreme clip limiter settings in bi-amp operating mode can ◊
result in balance shifting.
