Meyer Sound MJF-210 Powered Wedged Stage Monitor

Meyer Sound MJF-210 Powered Wedged Stage Monitor

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.

Features:

• Self-powered system guarantees simplified setup and operation
• Small lightweight footprint with no external amplification occupies less truck space
• Low profile cabinet preserves onstage sight lines
• Wide vertical coverage permits the freedom to move upstage and downstage
• High peak power ensures excellent transient response
• Flat frequency and phase responses yield high gain before feedback
