7.2 Arrayed Speaker Systems (Cluster)
If the loudspeakers are operated through an optional K&F System Controller, we recom-
mend to turn on the 'Top Low Cut' filter for clustered operation. Thus the frequency re-
sponse for this application can be optimised (see user’s manual of the controller).
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.
7.2.1 Horn not rotated
*If several 90° systems are clustered, unwanted interference effects may appear. As a
result, we do not generally recommend clustered configurations of CA 1001, CA
1201, CA 1215-9 and CA 1515-9 systems. If wide angles are to be covered, we rec-
ommend the use of several 60° or 65° systems in one cluster.
