INTRODUCING THE UPM-1P AND UPM-2P
LOUDSPEAKERS
Meyer Sound's UPM-1P ultra-compact wide coverage and
UPM-2P ultra-compact narrow coverage loudspeakers are
self-powered professional sound reinforcement loudspeak-
ers made for applications that require a small, inconspicu-
ous system capable of high sound pressure levels.

UPM-2P ultra-compact narrow coverage loudspeaker
In standalone under-balcony, front- or side-fill applications,
UPM-1P and UPM-2P loudspeakers can provide vocal
range reinforcement as a small PA system, while a full-range
system can be created with the addition of a separate sub-
woofer. Other features include:
■ Extremely low distortion
■ Uniform directional control on both the horizontal and
vertical axes
■ Dual 5-inch low-mid transducers
■ 1-inch metal dome high-frequency driver on constant
directivity symmetrical horns
■ Two-channel power amplifier
■ Proprietary phase-corrected active processing circuitry
Both the UPM-1P and UPM-2P use a 1-inch metal dome
tweeter on a symmetrical constant-directivity high-fre-
quency horn. With its 45-degree beamwidth, the UPM-2P
loudspeaker produces a narrow, symmetrical pattern for
precise coverage control, while the UPM-1P loudspeaker
offers a wider 100-degree symmetrical coverage pattern for
broad listening areas.

Optimized Control Electronics

Like all Meyer Sound self-powered loudspeakers, the UPM-
1P and UPM-2P exhibit superior performance across virtu-
ally all parameters. Because the amplifiers and control elec-
tronics are precisely optimized for each driver, the overall
system is able to produce more power with flatter response
and lower distortion. Self-powering also means simplifying
installation by eliminating amplifier racks and external drive
processing — allowing configuration of extensive distrib-
uted systems free from the signal losses imposed by long
loudspeaker cable runs or 70/100-volt wiring schemes. The
UPM-1P and UPM-2P loudspeakers also include a laser-
trimmed differential input stage for high common mode
rejection, and can be equipped with Meyer Sound's RMS™
remote monitoring system.
