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.

sConnect 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.
