EUROLIVE B1520DSP User Manual
The B1520DSP 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 B1520DSP 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 B1520DSP 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 B1520DSP.
They must be sufficiently earthed during and after the installation
process. Otherwise, electrostatic discharges may negatively affect the
operating characteristics of your equipment.
