Meyer Sound UPJ-1P Mid-Sized Point-Source Loudspeaker with 50 Degree Rotatable Horn, Weather Protection, and 3-Pin XLR

The UPJ-1P combines the advantages of self-powered systems with the placement and arraying flexibility afforded by a VariO™ rotatable horn. Though remarkably compact and lightweight, the UPJ-1P produces a robust linear peak SPL output of 125 dB with 18 dB crest factor, making it suitable for use either singly as a primary loudspeaker or in multi-cabinet horizontal or vertical clusters. Applications include audio-visual presentations, small- to medium-sized main sound reinforcement systems, fill, delay, effects, under-balcony or under-canopy coverage and distributed systems.

Features:

• Exceptional fidelity and extended high frequency enhance performance
• Compact package delivers surprising power capability
• Extraordinarily flat amplitude and phase response provide tonal accuracy and precise imaging
• Constant-Q horn affords uniform response throughout the coverage area
• Predictable array performance ensures system design flexibility
• VariO horn enables versatile coverage options, whether orienting loudspeakers horizontally or vertically
