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.
