EUROLIVE B415DSP
Linking several B415DSP:
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 B415DSP 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.
s Connect the LINE OUT connector of the first B415DSP
to the MIC/LINE input of the next B415DSP.
+ With several B415DSP speakers connected to each
other, their input impedance will be reduced by half
(two B415DSPs), or to one third (three B415DSPs),
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 B415DSP receives its audio signal
from the monitor or aux output of the mixing console. If additional
B415DSPs are to be used, you can loop the audio signal from the
first speaker to the next B415DSP using the line output. The
sound and volume of each B415DSP 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 instrumenteven
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 B415DSP 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 B415DSP 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 B415DSP 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
B415DSP. They must be sufficiently earthed during
and after the installation process. Otherwise,
electrostatic discharges may negatively affect the
operating characteristics of your equipment.
