perature. A smooth limiting characteristic
effectively protects the drivers without the
compression effects imposed by typical
limiters, allowing high output levels across
the drivers’ entire frequency range.
The internal electronics also provide active
signal processing, including phase correc-
tion circuitry that delivers flat frequency
and phase response over the entire oper-
ating range. Integrating a built-in low-pass
crossover while accepting a full-range sig-
nal, the UMS-1P’s input allows for simple
daisy-chain signal distribution and elimi-
nates the need for external crossovers.
Field-replaceable audio input modules ac-
commodate a range of applications. The
standard version offers looping XLR input
and output connectors, while an enhanced
looping version adds polarity switching
(the looping output is not affected) and
input attenuation (0 dB to -18 dB). A sum-
ming mono version with two inputs is also
available.
An extremely compact, self-powered sys-
tem, the UMS-1P ultra-compact subwoofer
provides powerful low-frequency exten-
sion in applications where both excellent
audio quality and an unobtrusive cabinet
size are required. The system’s output is
127 dB peak SPL within its operating range
of 25 Hz to 160 Hz. Although designed pri-
marily as a companion for Meyer Sound’s
UPM-1P wide coverage and UPM-2P narrow
coverage ultra-compact loudspeakers, the
UMS-1P is equally adaptable for use with
other Meyer Sound models such as the HD-1
high-definition studio monitor. The UMS-1P
may be used singly or stacked to provide
even greater low-frequency output.
The tuned bass-reflex enclosure houses
two 10-inch cone drivers, each powered
by a dedicated channel of an integral class
AB/bridged power amplifier with comple-
mentary MOSFET output stages. Total peak
power is 450 watts. Each channel incor-
porates a limiter that prevents driver over-
excursion and regulates the voice coil tem-

The standard UMS-1P is switchable between
the 115 V AC and 230 V AC ranges. A 100
V AC version is also available. The inte-
gral power supply suppresses high-voltage
transients and also provides EMI filtering.
Dual locking PowerCon connectors facili-
tate AC looping.
The UMS-1P’s durable enclosure is con-
structed from premium birch plywood and
is covered with a black textured hard-shell
finish. A hex-stamped steel grille and a
charcoal grey foam cover are included. A
pole mount for supporting a UPM-1P or
UPM-2P is fitted as standard. Options in-
clude custom color finishes, and cabinets
with no handles for fixed applications re-
quiring specific cosmetics.
The UMS-1P is compatible with the RMS™
remote monitoring system, which offers
comprehensive monitoring of system pa-
rameters on a Windows®-based network.
