Meyer Sound MJF-210-3 2x10" 3-Way Active Stage Monitor, 3-Pin Input

The MJF series boasts flat amplitude and phase responses, full-range bandwidth, and exceptional impulse response, along with Meyer Sound’s own Intelligent AC system 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 gives life to a high-performance monitor that meets the most rigorous demands of live production.

Ultra-low distortion gives vocals and instruments stunning accuracy, with low distortion and no signal coloration at high output levels and at low frequencies. Even vertical and horizontal coverage allows the performer to move freely while remaining in the sweet spot.

All components are optimized to work 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 reproduces audio faithfully with high intelligibility at high output levels with ample low-frequency headroom. The self-powered MJF-210 exceeds the stringent requirements of today’s touring applications, withstanding the rigors of road and stage while occupying a small, lightweight footprint and a fraction of the truck space of similar monitors requiring external amplification. The MJF-210’s phase-corrected 55Hz to18Hz frequency range ensures that vocals and instruments are reproduced accurately with low distortion and no signal coloration. Exhibiting flat phase and frequency responses, as well as exceptional impulse response, the MJF-210 surpasses the sonic capabilities of conventional stage monitors while offering the simplicity of self-powered setup and operation. The MJF-210’s durable, vented enclosure houses two high-power, long-excursion, 10- inch low-frequency drivers, as well as a 4-inch diaphragm compression driver coupled 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, ensuring optimal monitoring for the performer, permitting freedom to move upstage and downstage while remaining within the horn’s consistent, wide vertical coverage. Drivers are powered by a 3-channel, class D amplifier. The Intelligent AC™ power supply provides automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression.

MJF loudspeakers work with Meyer Sound’s RMS™ remote monitoring system, which provides comprehensive monitoring of system parameters from a Mac® or Windows®-based computer.
