CH 5 controls the MSL-4 down-fill system. Since the
main system is more powerful 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 systems combine properly in this area:
• Set the MSL-4 to the same polarity as the MSL-6 to
phase align the mid-hi frequencies.
• Use the CH 5 Array EQ filter to minimize the low-
mid rise caused by the MSL-4 array.
• Delay the down-fill to align it with the lower
MSL-6 system in their intersecting coverage area.
The polarity for the 650-P depends on the height and
distance of the measurement position from the flown and
subwoofer systems. The entire system should be measured,
phase-aligned, and equalized using the SIM System II
Sound Analyzer and CP-10 Parametric Equalizer.

The system from the previous example can be supple-
mented with a row of four DS-2Ps (or PSW-2s), sus-
pended below the lower MSL-6 array, to reinforce the
low frequencies. The MSL-4s are hung below the DS-2Ps
at 20
°
.

The connections for this system are the same as the
previous example except that the CH1 DS-2 output
drives the DS-2P system with the DS-2 & Sub Crossover
switch in. The lower MSL-6 system should be delayed to
align with the upper MSL-6 system in the area in which
their coverage overlaps. The MSL-4 should also be de-
layed to align with the lower MSL-6 system.
Refer to the Operating Instructions for the MSL-4, 650-P,
and DS-2P (or PSW-2) to design arrays for those speakers.
The MSL-6, MSL-4, and DS-2P systems should be set to
the same polarity. The polarity for the 650-P depends on
the height and distance of the measurement position
from the flown and subwoofer systems.
The entire system should be measured, phase-aligned,
and equalized using the SIM System II Sound Analyzer
and CP-10 Parametric Equalizer.
