INTRODUCTION
With an operating frequency range of 28 Hz to 160 Hz,
the dual 15-inch M2D-Sub loudspeaker complements the
M2D loudspeaker in reinforcement applications requiring
extended low-frequency headroom.
The M2D-Sub loudspeaker affords 138 dB SPL peak output
capability. It employs two Meyer Sound ferrouid cooled,
back-vented drivers each featuring a 4-inch voice coil with
a lightweight neodymium magnet structure. Each driver is
rated to handle 1200 AES watts.
NOTE: Power handling is measured under
AES standard conditions: Transducer driven
continuously for two hours with band-limited noise
signal having a 6 dB peak-average ratio.
An integral two-channel class AB/H complementary
MOSFET amplier provides very high burst capability,
and Intelligent AC performs automatic voltage selection,
allowing the unit to accommodate worldwide mains
voltages without manually setting a voltage switch.
Integral peak and rms limiters featuring Meyer Sound’s
TruPower
®
limiting technology protect M2D-Sub
components from over-excursion and over-heating while
assuring minimal power compression and maximum peak
headroom.
The M2D and M2D-Sub loudspeakers are tted with
Meyer Sound’s RMS remote monitoring system, allowing
the full range of operating parameters to be monitored
continuously over a network using a Windows
®
computer.
In addition, both loudspeakers are supported by the Meyer
Sound MAPP Online
®
multipurpose acoustical prediction
program for easy and accurate system design. The MAPP
Online prediction program allows quick prediction of
coverage, frequency response, impulse response and
maximum output of arrayed loudspeakers, and more.
NOTE: See Chapter 4, “Remote Monitoring
System,” and Chapter 5, “System Design
and Integration Tools,” for more information about
the RMS monitoring system and the MAPP Online
prediction program.
NOTE: Read this entire manual carefully
before conguring and deploying your M2D
and M2D-Sub system. In particular, pay careful
attention to the sections about safety issues.
