ULTRABASS BX4500H
3.2 Expanded setup with tuner and
connection to a mixing console
The wiring scheme shown here builds on the standard setup.
Fig. 3.2: Expanded setup
The output signal of your BX4500H can be taken directly at
the XLR D.I. output and fed to a microphone input of your mixing
console using a balanced microphone cable. Please ensure that
phantom power is switched off on the respective channel of
your mixer!
The D.I. output signal of your BX4500H is independent
of the OUTPUT control's setting. However, it depends
on all remaining settings and the effects loop.
If you own a tuner that is able to loop through and
mute the signal, we recommend connecting it to
the effects loop and
the output signal as long as you tune your instrument.

3.3 Connecting several loudspeakers

Needless to say, you can connect several loudspeakers (three
at the most) to the speaker outputs of your BX4500H, which are
wired in parallel. The figure below illustrates an example for
such a connection.
