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 overexcursion
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
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 available.
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
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
