Meyer Sound JM-1P - Manual (Page 8)

CHAPTER 1: INTRODUCTION

The JM-1P's sophisticated onboard amplification and pro-
cessing produces consistent and predictable results in any
system design. A proprietary two-channel, class AB/H
power amplifier with complementary MOSFET output stages
yields a total power output of 1275 W (2550 W peak). Built-
in signal processing includes an electronic crossover, driver
protection, and correction filters for achieving flat phase and
frequency responses. Each amplifier channel has peak and
rms limiters that prevent driver overexcursion and regulate
voice coil temperatures. Limiting activity is easily monitored
with the rear panel limit LEDs. The optional RMS™ remote
monitoring system provides comprehensive monitoring of
system parameters on a Windows
® -based computer.
The JM-1P's end plates include captive GuideALinks™ and
quick-release pins that allow the unit to be easily linked with
other JM-1Ps in arrays. The optional MPA-JM1 pickup plate
suspends JM-1P horizontal arrays of up to four units with
uptilt or downtilt from a single hanging point; two pickup
plates can suspend arrays of up to six units from a single
hanging point or motor using the MTGSB-4B spreader bar.
The optional MTG-JM1 grid suspends vertical arrays of up
to six JM-1Ps.
Constructed of premium birch plywood, the durable JM-1P
enclosure is coated with a black-textured, hard-shell finish.
A hex-stamped, steel grille with acoustical black mesh pro-
tects the unit's drivers. Other options include weather pro-
tection and custom color finishes for fixed installations and
applications with specific cosmetic requirements. The
optional MDB-JM1 dolly board transports the JM-1P on
caster wheels; multiple dolly boards can be interlocked to
transport up to three linked JM-1Ps.
