EUROLIVE B412DSP

Linking several B412DSP:
If you need more sound pressure, for example in larger rooms,

simply increase the number of loudspeakers on each stereo

side. You could place two B412DSP on each stereo side and

interconnect them (see Fig. 4.3). The loudspeakers can be stacked

or placed one beside the other. When you stack the speakers,

the carrying recesses built into the cabinets ensure the stability

of the stack. You can connect a microphone, a mixing console or

stereo signal source.

Connect the LINE OUT connector

of the first B412DSP

to the MIC/LINE input of the next B412DSP.

With several B412DSP speakers connected to each

other, their input impedance will be reduced by half

(two B412DSPs), or to one third (three B412DSPs),

etc. Always use the output impedance of the mixing

console as a basis for your calculations!

4.3 Other uses

Monitoring:
When used as a monitor, the B412DSP receives its audio signal

from the monitor or aux output of the mixing console. If additional

B412DSPs are to be used, you can loop the audio signal from the

first speaker to the next B412DSP using the line output. The

sound and volume of each B412DSP can be adjusted with their

own operating elements

(LEVEL),

(EQ HIGH) and

(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 B412DSP 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 B412DSP 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 B412DSP 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

B412DSP. They must be sufficiently earthed during

and after the installation process. Otherwise,

electrostatic discharges may negatively affect the

operating characteristics of your equipment.
