Meyer Sound UPJ-1P
The UPJ-1P combines the advantages of self-powered systems with the placement and array-
ing flexibility afforded by a VariO rotatable horn. Though remarkably 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.

Meyer Sound MSL-4
The MSL-4's built-in power amplifier and control electronics are contained in an easily ac-
cessible, field-replaceable module. The amplifier, a class AB/H design with complementary
MOSFET output stages, produces peak output of 1240 watts (620 watts per channel).
The integrated control electronics includes TruPower limiting for driver protection, as well as
active phase correction circuits to maintain exceptionally coherent phase response. Superior
common mode rejection from laser-trimmed differential inputs allows very long signal runs. An
Intelligent AC power supply affords automatic voltage selection, EMI filtering, soft current turn
-on and surge suppression to ensure system stability and long-term reliability.
Meyer Sound UPJunior
Meyer Sound's UPJunior ultracompact VariO loudspeaker brings the sonic signature, versa-
tile rigging, and extraordinary power-to-size ratio of the UPJ-1P to a smaller package. The UP-
Junior combines the advantages of a self-powered system with the placement and arraying flexi-
bility afforded by a VariO rotatable horn.
Though remarkably compact and lightweight, the UPJunior delivers a robust peak power
output of 126 dB SPL at 1 meter, making it suitable for use as either a single, primary loud-
speaker or within multi-cabinet horizontal and vertical arrays.
Meyer Sound MM-4XP : Miniature Loudspeaker
The MM‑4XP miniature loudspeaker is a self-powered loudspeaker designed forhigh-quality
distributed systems. Housed in a compact aluminum enclosure, the MM‑4XP is especially suit-
able for installations involving space limitations and visibility concerns, such as fill and spot
coverage, and hidden locations like chancel steps in houses of worship.
Meyer Sound UPM-1P
The UPM-1P is a remarkably compact, self-powered professional sound reinforcement loud-
speaker system. It is ideally suited to applications requiring a relatively small and inconspicuous
loudspeaker that can also provide high sound pressure levels, extremely low distortion, and uni-
form directional control.
