Meyer Sound UPJ-1P Mid-Sized Point-Source Loudspeaker with 50 Degree Rotatable Horn, Looping/Polarity/Attenuating Audio Input Module, 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

Looping, Polarity, and Attenuating Audio Input Module
The UPJ-1P can be equipped with either of two audio input modules: The Looping Audio Input module or the Looping, Polarity, and Attenuating Audio Input module. Both audio input modules have input and looping connectors, and LEDs for monitoring temperature and limiting. In addition, the Looping, Polarity, and Attenuating Audio Input module has a switch for swapping the signal’s polarity, and a knob for attenuating the input signal level to –18 dB.
