CHAPTER1
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.
