7.2 Arrayed Speaker Systems (Cluster)
If the loudspeakers are operated through the optional K&F C2 System Controller, we
recommend turning on the ‘Top Low Cut’ switch for clustered operation. Thus the fre-
quency response for this application can be optimised (see also K&F C2 User's Manual).
When operating the systems without the K&F C2 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 systems.
If wide angles are to be covered, we recommend the use of several systems with ro-
tated horns in one cluster.
