The Meyer Sound USW-1P cabinet houses two 15-inch drivers,
each powered by a dedicated channel of the proprietary built-in class
AB/bridged power amplifier (550 watts total peak power) with complementary
MOSFET output stages. 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.
Integrating a built-in low-pass crossover while accepting a full-range
signal, the USW-1P’s input allows for simple daisychain 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 available.
The amplifier/processing package, also field-replaceable, incorporates
Meyer Sound’s Intelligent AC™ system, which performs automatic
voltage selection, EMI filtering, soft current turn-on and surge suppression.
Intelligent AC allows failsafe operation worldwide, with no need to manually
select the AC mains voltage.
The Meyer Sound USW-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. Standard rigging points are three ring and stud pan fittings
(on top) with a load rating of 420 lbs (190.51 kg) per fitting, based
on a 5:1 safety factor. (3/8"-16 and M10 metric nut plates are also
available.) The cabinet’s rectangular shape makes groundstacking
on the floor or stage a simple and stable option. Options available include
weather protection and finishes in custom colors for applications requiring
The Meyer Sound USW-1P is compatible with the RMS™ remote monitoring
system, which offers comprehensive monitoring of system parameters on
a Windows®-based network.
