| The Meyer Sound M1D provides a substantial peak SPL of
125 dB at 1 meter with an operating frequency range of 60 Hz to 18 kHz
and is designed specifically for implementing vertical curvilinear arrays
of up to 16 cabinets having 0- to 8-degree splay between adjacent units.
This design affords the flexibility to tailor vertical coverage by varying
the number and splay of cabinets in the array while maintaining a consistent
100° horizontal coverage.
The Meyer Sound M1D loudspeaker system comprises two 5-inch cone drivers
and three 0.75-inch high-frequency metal dome tweeters with neodymium
magnets. To assure the smoothest response in the critical midrange, the
Meyer Sound M1D incorporates a complex crossover design similar to that
pioneered in Meyer Sound’s UPM loudspeakers. At the lowest frequencies,
both 5-inch drivers combine to reproduce powerful, coherent bass. In the
mid frequencies, however, the crossover feeds the signal to only one driver;
this technique eliminates interference between the two drivers (that would
otherwise occur at shorter wavelengths) in order to maintain optimal polar
and frequency response characteristics. The three vertically aligned dome
drivers act as a small line array, focusing the sound into a tight vertical
coverage pattern while the constant-directivity horn maintains broad horizontal
coverage.
The bi-amplified Meyer Sound M1D incorporates a complementary MOSFET
power amplifier module with 500 watts total burst capability, together
with active crossover and optimized frequency and phase response correction
circuitry. An Intelligent AC power supply selects the correct operating
voltage in the range of 90 to 264 V AC at 50 or 60 Hz, allowing international
use without manually setting voltage switches. The Intelligent AC supply
also performs protective functions to compensate for hostile conditions
on the AC mains. Integral peak and rms limiters protect the loudspeaker
components from over-excursion and over-heating.
The Meyer Sound M1D’s vented, trapezoidal cabinet is constructed
from multiply hardwood and has a textured hard shell finish. The Meyer
Sound M1D incorporates QuickFly rigging as standard, and utilizes connecting
links that are secured to the steel and aluminum rigging end frames by
quick release pins. An ingenious arrangement of rigging holes allows quick
and easy adjustment of cabinet splay for maximum freedom in customizing
vertical coverage. The optional QuickFly MG-1D multipurpose grid allows
either flying or ground stacking various combinations of Meyer Sound M1D
and Meyer Sound M1D-Sub. Up to 16 Meyer Sound M1Ds (or the equivalent
weight of M1D and M1D-Sub) with a 7:1 safety factor may be flown, or up
to eight M1Ds or four M1D-Subs may be ground stacked. For flying only,
the simpler optional MTG-1D will support up to 16 Meyer Sound M1Ds (or
the equivalent weight of M1D and M1D-Sub) with a 7:1 safety factor.
The Meyer Sound M1D comes equipped with Meyer Sound’s RMS remote
monitoring system as standard. RMS allows the full range of operating
parameters to be monitored over a network using a Windows computer.
