The Meyer Sound MJF-212A is a self-powered
stage monitor loudspeaker
designed to meet critical requirements
in professional applications. Exhibiting
flat amplitude and phase responses, full-range
bandwidth, and exceptional impulse
response, the MJF-212A far exceeds the
capabilities of conventional stage monitors
while offering the simplicity of setup and
operation provided by self-powered
systems.
“We named the MJF-212A in recognition of the role our 20-year relationship with the Montreux Jazz Festival has played in our product development history...Having so many musicians try it out at a major festival resulted in us getting a lot of valuable real-world opinions — all very enthusiastic”

The MJF-212A monitor’s phase-corrected
frequency range of 55 Hz to 18 kHz
enables accurate reproduction of both
vocals and instruments with high gain
before feedback, and provides excellent
intelligibility at high output levels with low
distortion and no coloration added to the
signal. The MJF-212A is also engineered
to have exceptional low-frequency
headroom, which can be helpful in some
applications such as the extreme lowfrequency
demands of high-level drum
monitoring. The face of the low-profile
cabinet slopes at 40 degrees from the stage
to permit optimal placement relative to the
talent, while its medium-Q horn provides
even coverage in both the horizontal and
vertical planes.
The loudspeaker’s high-frequency section
comprises a 4-inch diaphragm compression
driver coupled to a symmetrical (50 degrees
horizontal by 50 degrees vertical) constant
directivity horn. A pair of high-power
12-inch neodymium magnet cone drivers
with 4-inch voice coils, mounted in an
optimally vented enclosure, reproduces
low frequencies.
Each driver is powered by one channel of
a three-channel class AB/H amplifier that
employs complementary power MOSFET
output stages to provide total burst output
of 1275 watts (2 x 500 watts, 1 x 275 watts),
2550 watts total peak. The MJF-212A
incorporates Meyer Sound’s Intelligent AC
system for automatic voltage selection, EMI
filtering, soft current turn-on, and surge
suppression.
The cabinet is constructed from premium
birch plywood and coated with a durable,
textured black finish. A metal grille lined with
acoustical black mesh protects the drivers.
The rugged MJF-212A includes plastic skids
on the bottom of the unit to prevent damage
to the enclosure or stage floor.
The MJF-212A can be integrated into Meyer
Sound’s RMS remote monitoring system
with the addition of an optional module.
RMS is a Windows-based computer application
for monitoring the full-range of amplifier
and limiter operating parameters.

"The MJF-212A stage monitors are able to cut through and still sound full. I can hear and feel my voice above the wall of 'Tallica. For some reason we like it loud!"
