CHAPTER 1
INTEGRATED AMPLIFIER AND PROCESSING
As a self-powered loudspeaker, the MJF-212A incorporates
a high-power, three-channel, class AB/H power amplifier
using complementary power MOSFET output stages. In
addition, sophisticated control circuitry is housed within
the cabinet, dramatically simplifying setup and installation.
To use the MJF-212A, simply supply power distribution to
the stage monitor, connect a line level signal, and it’s ready
— freeing you to focus on mixing instead of making the
monitor work.
The on-board amplifier delivers 1275 watts of total burst
power (2 x 500 watts, 1 x 275 watts) and 2550 watts peak.
Dedicated limiters extend the life of the drivers at very high
levels and prevent severe non-linear circumstances.

This modular, field-replaceable amplifier/processing package
also incorporates Meyer Sound’s Intelligent AC™ power
supply, which automatically adjusts for common line voltage
worldwide and provides both soft turn-on and transient
protection. The MJF-212A monitor can be optionally fitted
with Meyer Sound’s exclusive RMS module, allowing you
to monitor and troubleshoot an entire RMS-equipped
Meyer Sound system remotely from your Windows-based
computer.
NOTE: In order to use RMS, you will need
Meyer Sound’s RMS software, an interface
card, and a computer running Windows
®
2000/XP
or later.
NOTE: Complete acoustical and electrical
specifications are covered in Appendix B.
TOTAL SYSTEM APPROACH
The MJF-212A monitor integrates seamlessly with other
Meyer Sound products, with compatible acoustical and
performance characteristics. Used in conjunction with other
Meyer Sound self-powered loudspeakers, the MJF-212A
monitor can provide you with everything you need to
design and implement complete self-powered systems for
optimum performance in venues of any size or shape.
