9.2 Arrayed Speaker Systems (Cluster)
If the loudspeakers are operated through an optional K&F System Controller, we rec-
ommend turning on the 'Top Low Cut' filter for clustered operation. Thus the fre-
quency response for this application can be optimised (see user’s manual of the control-
ler).
If the Line 212 Systems are operated in a cluster without a K&F System Controller
(speakers are set up directly next to one another), then lower the '
EQ LOW CUT' fre-
quency as described below!
EQ LOW CUT
Frequency 120Hz
Quality (Q) 0.55
Bandwidth (oct.) 2.35
Level -2.95dB
1.
If several Line 212-6 with a horn coverage pattern of 65°h x 50°v are arranged on
one side (cluster / array), it is recommended for the Line 212-6 to have a horizontal
array angle of 38.5° to one another (see fig. 2).
2. In a cluster comprised of a combination of the Line 212-6 with Line 212-9, we
recommend an array angle of 45° (see fig. 3).
3. With a rotated horn (Line 212-6 standing: 50°h x 65°v / Line 212-9 standing: 50°h
x 90°v), an array angle of 30° is recommended for both versions (see fig. 1).
Because increased interference effects occur when several 90° systems are arranged
next to one another, the clustering of several Line 212- 9 is only conditionally recom-
mendable.
