• 
The loudspeakers can be connected using communications cable I-Y (St) Y n x 2 x 0.8 mm or 
comparable
, for example. If a different, comparable cable type is used, please bear in mind the 
output and cable length required. 
•  Spur lines with volume controllers are not monitored! 
•  To ensure correct loudspeaker monitoring by means of impedance measurement, a maximum of 
20 loudspeakers are permitted per line. If more than 20 loudspeakers are used, an End of Line 
module (EOL) must be connected.
