Meyer Sound¹s New JM-1P Arrayable Loudspeaker

Meyer Sound¹s New JM-1P Arrayable Loudspeaker Combines Powerful Performance

with Precise, Scalable Horizontal Coverage



Meyer Sound has introduced the JM-1P arrayable loudspeaker, a self-powered

high-Q system designed to integrate seamlessly in tight-packed clusters

where horizontal coverage must be predictably scaled to exacting

requirements. Distinguished by its precisely defined 20-degree horizontal by

60-degree vertical pattern, the JM-1P delivers controlled coverage while

minimizing reverberation in large or reflective acoustical environments.



With a remarkably consistent polar response and trapezoidal enclosure

patented by Meyer Sound, the JM-1P delivers optimum performance in

tight-packed arrays providing horizontal coverage that is proportional to

the number of units deployed. Single JM-1P cabinets can be used as a

point-source system in either horizontal or vertical orientations. The JM-1P

is suited to critical quality applications including theatres, houses of

worship, theme parks, stadiums, concert halls, and nightclubs. In touring

sound, it offers flexible solutions for center- and side-fill systems.



Meyer Sound¹s experience in point-source systems dates back to 1980 when

John Meyer, CEO of Meyer Sound, patented the trapezoidal cabinet shape with

the release of the UPA loudspeaker. The JM-1P features a Meyer Sound¹s

patented REM ribbon emulation manifold technology, which results in low

distortion and a tight pattern control, while a constant-Q horn ensures a

uniform response throughout the coverage area.



The JM-1P¹s exceptional power-to-size ratio and flexible Quickfly® rigging

options allow for easy mounting and flying in a variety of applications.

Captive sliding rigging links on the front and back of the cabinet

facilitate easy arraying, and optional pickup and array plates are available

for flying horizontal arrays of up to five JM-1P cabinets. A top grid

receives links and pins directly from the JM-1P cabinet and allows for flown

vertical arrays of up to four cabinets.



³The JM-1P gives sound designers the flexibility to accurately tailor

coverage in highly reverberant or oddly shaped environments,² notes John

Meyer. ³You can conform your horizontal coverage to fit the room, so you

maintain a smooth response at all seats while avoiding echoes or excessive

reverberation.²



The JM-1P¹s precise high-frequency section is driven by a 4-inch diaphragm

compression driver, complemented by a 15-inch, long-excursion cone

transducer for the low-mid section. Power is supplied by a dual-channel

class AB/H amplifier with a total power output of 1275 W (2550 W peak),

while onboard processing includes electronic crossover, comprehensive driver

protection, and correction filters for flat frequency and phase responses.



Performance of the JM-1P is exemplary in all respects, with a wide operating

frequency range of 55 Hz to 18 kHz, and a maximum peak SPL of 136 dB (at 1

m). The optional RMS remote monitoring system allows comprehensive

monitoring of system parameters on a Windows®-based computer. The JM-1P can

be controlled with the Galileo digital loudspeaker management system and

presets for JM-1P arrays will be available to provide mid-bass and bass

management.



Designed and manufactured at Meyer Sound headquarters in Berkeley, Calif.,

the JM-1P arrayable loudspeaker will begin shipping in August 2009.
