QUIPMENT

The cabinet, exposed electronic circuitry,
and its accompanying drivers can receive
protective treatment while still in the
factory that permits safe use in wet
conditions. Additionally, a rain hood can
be fitted to shield cables and

electronics. Do not install a unit
outdoors without weather protection!
Contact Meyer Sound for more
information.

NOTE: All Meyer Sound products must be

used in accordance with local, state,

federal, and industry regulations. It is
the owner’s and/or user’s
responsibility to evaluate the
reliability of any rigging method for
their application. Rigging should be
done only by experienced
professionals.

Meyer Sound self-powered loudspeaker
systems are designed complementarily in
frequency and phase to maximize power
through each crossover point in a
complete system.

ETUP

We strongly recommend using a
minimum of two DS-4Ps in the same
array. A complimentary ratio of one
Meyer Sound MSL-4 to one DS-4P will
give users extra power headroom in the
70Hz to 200Hz band pass.

To integrate different types of Meyer
Sound self-powered loudspeakers into a
complete system, we recommend using
the Meyer Sound LD-1A Line Driver. The
LD-1A has two channels equipped to
control a full-range main system, and six
auxiliary channels for down-fill, front-
fill, and delay systems. The LD-1A
maintains signal integrity for long cable
paths.

The LD-1A’s filters have been designed
to compliment and work with the
internal filters in Meyer Sound’s self-
powered products in order to minimize
time offset while maximizing power
addition when these products are added
together. The LD-1A further gives users
the ability to balance level between the
products within a system.

Figure 1 illustrates the recommended
settings for the DS-4P’s use with MSL-4s
and 650-P Subwoofers. The DS-4P has
been engineered in both frequency and
phase response to work with the LD-1A’s
filters when used in a co-planar
configuration. All of the products
contain their own active bandlimiting
networks, however these additional
filters are required when the three
products are added together.

The DS-4P has been optimized for the
LD-1A’s Array EQ in combination with
the Low Cut filter IN on the Mid-High
output. These two filters allow the MSL-
4/DS-4P to add together in phase
response through their crossover range
to give you optimal power addition.

A typical system configuration will be
MSL-4s flown in the same array with DS-
4Ps and subwoofers on the ground in
half space. If the subwoofer arrays are
offset vertically to the MSL-4/DS-4Ps,
then some minor delay compensation
may be required to optimize the
system’s crossover range between the
DS-4Ps and the subwoofers.

COMPLETE SYSTEMS

NOTE: In a typical flown array with a

one-to-one ratio of MSL-4s to DS-4Ps,
a gain adjustment of +/- 2dB should
be expected depending on the array’s

splay angles. If the DS-4Ps are put on
the ground (in half space), the relative
levels will change to approximately
6dB less gain to the DS-4Ps.
