LD-1A with 650-P and MSL-4
Using the LD-1A’s Lo Cut filter for the CH 1 Mid-Hi
output also eliminates the low frequency rise caused by
the frequency response overlap between the MSL-4 and
650-P. Although a typical MSL-4:650-P ratio is 2:1, CH 1’s
Sub and Mid-Hi level controls allow this ratio to vary
while maintaining control of the spectral balance of the
system. The DS-2 & Sub Crossover switch should be
out

Including subwoofers in a flown cluster provides a
smooth frequency image because the low and mid-hi
frequencies are produced from speakers located close
together. The identical dimensions of the PSW-2 and
MSL-4 allow them to be easily flown together.
The CH 1 Mid-Hi output drives the MSL-4 with the Lo
Cut filter in. The CH 1 Sub and DS-2 outputs drive the
650-Ps and PSW-2s with the DS-2 & Sub Crossover
switch out, which sends a full-range signal with inde-
pendent level control to each speaker.
Set the MSL-4 and PSW-2 to the same polarity. The polarity for
the 650-P depends on the height and distance of the measure-
ment position from the subwoofers and flown cluster.
LD-1A with MSL-4, DS-2P, and 650-P
Adding the DS-2P to an MSL-4/650-P system enhances
LF power and clarity. With the DS-2 & Sub Crossover
switch in, the DS-2P and 650-P each receive signals
optimized for their frequency response capabilities.
The MSL-4 is driven from the CH 1 Mid-Hi output with
the Lo Cut filter in to minimize the overlap in frequency
response with the DS-2P and 650-P. Set the 650-P to the
opposite polarity to the MSL-4 and DS-2P.
Set the 650-P to the opposite polarity to the DS-2P and
MSL-4.
650-P and 650-R2
Although it is preferable to employ the 650-P in a
completely self-powered system, the 650-P can be used
with the 650-R2 externally amplified subwoofer if:
• the B-2EX CEU is set to the maximum output
level;
• the 650-R2’s amplifier is set to 26 dB gain;
• the 650-R2’s amplifier is set to the opposite polarity
of the 650-P.
POLARITY NOTE: It is advisable to check the polarity of
adjacent 650-P and 650-R2 cabinets by following the
instructions in the Verifying Driver Polarity section on
page 10.
