7.2 Arrayed Speaker Systems (Cluster)
If the loudspeakers are operated through the optional K&F System Controller, we rec-
ommend to turn on the 'Top Low Cut' filter for clustered operation. Thus the fre-
quency response for this application can be optimised (see also user’s manual of the
K&F System 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 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.
