Horn-Loaded Loudspeaker MSL-6

The MSL-6, Meyer SoundÕs
largest self-powered speaker,
is ideally suited for large-scale
vocal public address
applications as a stand-alone
system, and for musical sound
reinforcement in combination
with Meyer self-powered
subwoofers and/or the DS-2P
mid-bass speaker. The MSL-6
features a 25¡ vertical coverage
angle, permitting long-throw
arrays with up to three vertical
rows with minimal overlap
between coverage areas.
The center and outer high
frequency horns utilize
separate amplifier and control
electronics to achieve a 30¡
horizontal coverage angle for
a single MSL-6. Tight-packing
two units together yields a 60¡
coverage angle. Since the
MSL-6 is intended for tight
packing only, array design is
simple and modular: each
additional unit increases the
horizontal coverage by 30¡. The
maximum horizontal array size
is twelve units, resulting in a
circular array with
360¡coverage.
The MSL-6 contains amplifier
and control electronics for two
12Ó low frequency cone drivers
and three high frequency horn
drivers (2Ó throat, 4Ó diaphragm)
in a compact trapezoidal
cabinet. Each 12Ó driver is
independently amplified and
contained in a horn-loaded
vented enclosure. This integrated design improves
performance, durability, and
reliability, eliminates amplifier
racks, and simplifies setup
and installation.
The MSL-6 has twelve
pivoting lift rings (six on top,
six on bottom), each with
a maximum working load
capacity of 1500 lb (5:1 safety
factor). Despite the inclusion
of amplifier and control
electronics, the MSL-6 is 14Ó
shorter, and 25 lbs. lighter
than the MSL-5. The MSL-6
cabinet is reinforced internally
with steel girders.
The MSL-6 employs
TruPower limiting (TPL), the
first limiting technique that
accurately calculates the power
dissipation within the speaker.
TPL accounts for varying
speaker impedance by
measuring current, in addition
to voltage, to compute the power dissipation and voice
coil temperature.
TPL improves system
performance before and during
limiting by allowing the
speaker to deliver its highest
SPL across its entire frequency
range. TPL also eliminates
long-term power compression
when the MSL-6 is operated at
high levels for prolonged
periods and extends the
lifetime of amplifier and
driver components.
The MSL-6 can be equipped
to operate with the Remote
Monitoring System (RMS)
network and software
application. RMS displays
signal and power levels, driver
and cooling fan status, limiter
activity, and amplifier
temperature for all speakers
in the network on a
Windows based PC.
