EUROLIVE B1520DSP User Manual

The B1520DSP al ows 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 ful y 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 instal ation 
process. Otherwise, electrostatic discharges may negatively affect the 
operating characteristics of your equipment.
