Meyer Sound MJF-210-3 Active Stage Monitor

Meyer Sound MJF-210-3 Active Stage Monitor

The MJF series is boasting about the flat amplitude and phase responses, full-range bandwidth, and exceptional impulse response, along with Meyer Sound’s own Intelligent AC system intended for automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression.

A perfect balance of potent power, remarkable fidelity, small footprint, and minimal weight is perfectly giving life to a high-performance monitor that is meeting the most rigorous demands of live production.

Ultra-low distortion is professionally designed for giving vocals and instruments stunning accuracy, along with low distortion and no signal coloration at high output levels and at low frequencies. Even vertical and horizontal coverage is allowing the performer for moving freely and remaining in the sweet spot at the same time.

All components are being optimized for working seamlessly in a robust, reliable system that withstands the rigors of touring. Units have a durable finish, a protective metal grille, and protective bottom rubber strips.

The MJF-210 low-profile high-power stage monitor is designed for reproducing the audio faithfully along with high intelligibility at high output levels that comes with ample low-frequency headroom. The self-powered MJF-210 is exceeding the stringent requirements of today’s touring applications, withstanding the rigors of road and stage and occupying a small, lightweight footprint and a fraction of the truck space of similar monitors that required external amplification at the same time. The MJF-210’s phase-corrected 55Hz to18Hz frequency range is designed for ensuring that vocals and instruments are reproduced accurately along with low distortion and no signal coloration. Exhibiting flat phase and frequency responses, as well as exceptional impulse response, the MJF-210 surely surpasses the sonic capabilities of conventional stage monitors and offering the simplicity of self-powered setup and operation at the same time. The MJF-210’s durable, vented enclosure is housing two high-power, long-excursion, 10- inch low-frequency drivers, as well as a 4-inch diaphragm compression driver partnered to a 50-degree horizontal by 70-degree vertical constant directivity horn. The face of the low-profile cabinet slopes 35 degrees from the stage, that ensures optimal monitoring for the performer, permitting freedom for moving upstage and downstage and remaining within the horn’s consistent, wide vertical coverage at the same time. Drivers are powered by a 3-channel, class D amplifier. The Intelligent AC™ power supply is providing an automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression.

MJF loudspeakers are working along with Meyer Sound’s RMS™ remote monitoring system, which is capable of providing an comprehensive monitoring of system parameters from a Mac® or Windows®-based computer.
