The new MJF-212 is a self-powered stage monitor loudspeaker designed by to meet critical requirements in professional applications, such as use as a main vocal monitor, high-output drum or keyboard monitor, or as a sidefill monitor in small- to medium-scale systems. Exhibiting flat amplitude and phase responses, full-range bandwidth and exceptional impulse response, the MJF-212 far exceeds the capabilities of conventional stage monitors while offering the simplicity of setup and use provided by self-powered systems.

“We named the MJF-212 in recognition of the role our 20-year relationship with the Montreux Jazz Festival has played in our product development history,” says Meyer Sound executive vice president Helen Meyer. “The festival has often been the site for the first serious field testing of our new products. At this year’s festival, the newcomer was the MJF-212. 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-212 monitor’s phase-corrected frequency response of 60 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 face of the low-profile cabinet slopes at 40 degrees from the stage to permit optimal placement relative to the talent while preserving sightlines.

The MJF-212’s high-frequency section comprises a 4-inch diaphragm compression driver coupled to a symmetrical (50º horizontal by 50º vertical) constant-directivity horn. This medium-Q horn provides even coverage in both the horizontal and vertical planes.

A pair of high-power 12” neodymium magnet cone drivers, mounted in an optimally vented enclosure, reproduces low frequencies. Each of the drivers 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/2250 watts peak, ensuring excellent transient response. The MJF-212 incorporates Meyer Sound’s Intelligent AC circuitry for automatic voltage selection, EMI filtering, soft current turn-on and surge suppression. The rugged cabinet is constructed from premium birch plywood and coated with a durable, textured black finish.

The MJF-212 can be integrated into Meyer Sound’s RMS™ remote monitoring system with the addition of an optional module. RMS is a Windows-based program for monitoring a full range of amplifier and limiter operating parameters.
