Monitoring:
When used as a monitor, the B1220DSP receives its audio signal from the monitor
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

(LEVEL),
(7)
(EQ HIGH) and
(8)
(EQ LOW).
Keyboard amplification:
Guitarists and bassists usually have their own amplifiers on stage to make
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.
vIn wparticular 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.
