Meyer Sound JM-1P Arrayable Point-Source Loudspeaker with 3-Pin XLR and Remote Monitoring System
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
