Stereo operation with a subwoofer6.2
Using a crossover, the main stereo output signal of a mixing
console is split into a stereo signal and a mono signal, whereby
the mono signal covers the lower frequency range and the stereo
signal carries the rest of the frequencies. Then, the stereo signal
is connected to a stereo power amplier. A B1520 PRO is connec-
ted to each of the amp’s outputs. The mono subwoofer signal is
connected to one channel of an additional power amplier, which
is powering one B1800X PRO subwoofer.

monitoring system and a subwoofer
This example shows the use of two B1520 PROs as FOH louds-
peakers and one B1220 PRO used as a oor monitor on stage.
The FOH loudspeakers reproduce the main stereo output signal
from the mixing console, while the stage monitor is fed an inde-
pendent monitor mix through a mono monitor send (Aux Send).
A separate subwoofer output feeds a B1800X PRO subwoofer
with the bass signal. Two stereo power amps are required for this
application, whereby one amp reproduces the main stereo signal,
and the other one reproduces both mono signals (subwoofer and
monitor signal).
