When operating the systems without a K&F System Controller in a clustered con-figuration, the signal level of
frequencies below 300 Hz should be reduced by 3-4 dB.
10.2.1 Horn not rotated
*If several 90° systems are clustered, unwanted interference effects may appear. As a result, we do not gen-
erally recommend clustered configurations of CA 1201, CA 1215-9 and CA 1515-9 systems. If wide angles
are to be covered, we recommend the use of several 60° or 65° systems in one cluster.
