8 EUROLIVE B2520 PRO/B1800X PRO/B1520 PRO/B1220 PRO User Manual
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
connected 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.

This example shows the use of two B1520 PROs as FOH loudspeakers 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 independent 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).
