6. APPLICATION EXAMPLES
6.2 Stereo operation with a subwoofer
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 amplifier. An E1520 is connected
to each of the amps outputs. The mono subwoofer signal is
connected to one channel of an additional power amplifier, which
is powering one E1800X subwoofer.

6.3 Stereo operation with
a stage monitor and a subwoofer
This example shows the use of two E1520s as FOH
loudspeakers and one E1220 used as a floor monitor on the
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 an E1800X
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).
