LD-1A with CQ and 650-P
Activating the Lo Cut filter on the LD-1A for the Mid-Hi
output also eliminates the low frequency rise caused
by the overlap between the CQ and 650-P. Although a
typical CQ : 650-P ratio is 2:1, separate Sub and Mid-Hi
level controls on the LD-1A allow the ratio to vary
while maintaining control of the spectral balance of
the system.

This example shows the LD-1A integrating a complete
system of speakers appropriate for a large venue.
Although channels 1, 3, and 5 constitute half of a
complete system, channels 2, 4, and 6 can be used
with identical connections to create the other half of
the system. The MSL-4 mid-hi, DS-2P mid-bass, and
CQ down-fill speakers are flown; the 650-P subwoofers
are on the floor.

The Mid-Hi and CH 3 outputs drive the inner three
and outer two speakers, respectively, of the MSL-4
array. These two outputs apply appropriate levels for
speakers directed at audience locations at different
distances from the main system. The diagram shows the
additional mid-hi output created by connecting the
CH 1 Loop to the CH 3 input. Using a Y-connection at
the CH 1 input, as shown for the down-fills, accomplishes
the same signal routing.

The Lo Cut and Array EQ switches for the Mid-Hi and
CH 3 outputs should be in. The Lo Cut filter eliminates
the rise caused by the overlap between the MSL-4 and

the low-mid rise caused by the MSL-4 array.

CH 5 controls the CQ down-fill system. Since the main
system is normally set to a higher volume than the
down-fill system to project farther into the venue, the
main system is audible in the down-fill’s coverage
area. To insure that the speakers combine properly in
the overlapping coverage area:
