EUROLIVE B1220DSP
4.3 Other uses
Monitoring:
When used as a monitor, the B1220DSP receives its audio signal
from the monitor or aux output of the mixing console. If additional
B1220DSPs are to be used, you can loop the audio signal from
the first speaker to the next B1220DSP using the line output.
The sound and volume of each B1220DSP can be adjusted with
their own operating elements {3} (LEVEL), {7} (EQ HIGH) and
{8} (EQ LOW).
Keyboard amplification:
Guitarists and bassists usually have their own amplifiers on stage
to make sure they can hear their own instrument - even when
no monitors are used. In particular on smaller stages, the power
delivered by these amps is enough to match the volume
produced by other sound sources on stage. Things are different
with keyboards and synthesizers as these usually have no built-
in speakers. The B1220DSP allows you to connect and mix two
keyboards. If you want to play more than two keyboards, you
can use a submixer (e.g. MicroMIX MX400) to mix down the
signals and route them to the B1220DSP using submixer output
connectors. The second MIC/LINE input can be used to connect
the monitor signal from the PA mixing console, so that you can
also hear the other members of your band.
5. Installation
Both audio inputs and outputs of the BEHRINGER B1220DSP
are fully balanced. To maximize interference compensation, try
to establish balanced connections to other equipment, whenever
possible.
+ Make sure that only competent people install your
B1220DSP. They must be sufficiently earthed during
and after the installation process. Otherwise,
electrostatic discharges may negatively affect the
operating characteristics of your equipment.
