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.  
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 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 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.  
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.  
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.  
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 UMS-1P is compatible with the RMS™  
remote monitoring system, which offers  
comprehensive monitoring of system pa-  
rameters on a Windows®-based network.
