An extremely compact, self-powered system, 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 primarily 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 complementary MOSFET output stages. Total peak
power is 450 watts. Each channel incorporates a limiter that prevents driver over-excursion and regulates the voice coil temperature. 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 correction circuitry that delivers flat frequency
and phase response over the entire operating range. Integrating a built-in low-pass
crossover while accepting a full-range signal, the UMS-1P's input allows for simple
daisy-chain signal distribution and eliminates the need for external crossovers.
Field-replaceable audio input modules accommodate 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 summing mono version with two inputs is also
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 integral power supply suppresses high-voltage
transients and also provides EMI filtering.
Dual locking PowerCon connectors facilitate AC looping.
The UMS-1P's durable enclosure is constructed 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 include custom color finishes, and cabinets
with no handles for fixed applications requiring specific cosmetics.
The UMS-1P is compatible with the RMS
remote monitoring system, which offers
comprehensive monitoring of system parameters on a Windows-based network.
UMS-SM Single Mount Version
The UMS-SM subwoofer is a version of the UMS-1P subwoofer with threaded end plates for single-mount configurations with the UMS-SM U-bracket. The UMS-SM end plates are factory-installed (with the U-bracket) and not available as an upgrade option for the UMS-1P. The UMS-SM retains the same acoustical and electrical characteristics of the UMS-1P.
