The UPJ-1P combines the advantages of self-powered systems with the place- ment and arraying flexibility afforded by a VariOTM rotatable horn. Though remark- ably compact and lightweight, the UPJ-1P produces a robust peak power output of 128 dB SPL at 1 meter, making it suitable for use either singly as a primary loudspeaker or in multi-cabinet horizontal or vertical arrays. Applications include A/V presenta- tions, small- to medium-sized main sound reinforcement systems, fill, delay, effects, under-balcony or under-canopy coverage and distributed systems.
