Meyer Sound JM-1P RMS Arrayable Point-Source Speaker/Weather Protected/3-Pin/Remote Monitoring/Loop

Meyer Sound JM-1P RMS Arrayable Point-Source Speaker/Weather Protected/3-Pin/Remote Monitoring/Loop

The JM€‘1P self-powered loudspeaker is a high-Q, arrayable loudspeaker suited for a wide range of applications. Utilizing Meyer Sound€™s patented REM® technology and trapezoidal cabinet design, the JM€‘1P can be deployed in tightly-packed array clusters to deliver coverage that is proportional to the number of units in the array. While JM€‘1P point source arrays are optimized for horizontal installations, they can also be used vertically when necessary. With its scalable coverage and versatile QuickFly® rigging options, the JM€‘1P loudspeaker can be used for touring, rental, and fixed installations.

Features:

• Tightly controlled coverage is scalable proportional to the number of arrayed units
• Exceptional size to power ratio
• QuickFly rigging offers the flexibility of both horizontal and vertical arrays
• Consistent and predictable array performance ensures accurate system design
