Meyer Sound USW-1P - Manual

Integrating a built-in low-pass crossover
while accepting a full-range signal, the
USW-1P’s input allows for simple daisy-
chain signal distribution and eliminates the
need for external crossovers. Field-re-
placeable audio input modules accommo-
date a range of applications. The standard
version offers looping XLR input and out-
put connectors, while an enhanced looping
version adds polarity switching (the loop-
ing output is not affected) and input atten-
uation (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 fail-
safe operation worldwide, with no need to
manually select the AC mains voltage.

Combining advanced loudspeaker technol-
ogy with equally advanced power capabili-
ties, the Meyer Sound USW-1P self-pow-
ered subwoofer provides flat, low-fre-
quency response from 35 Hz to 180 Hz. The
USW-1P performs seamlessly within a full-
range system, in conjunction with UPA-
1P, UPA-2P and UPJ-1P loudspeakers. The
USW-1P is also fully compatible with other
Meyer Sound self-powered loudspeakers.

The 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 compres-
sion effects imposed by typical limiters, al-
lowing high output levels across the driv-
ers’ entire frequency range.

Rigging

The USW-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.
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 specific cosmetics.

The USW-1P is compatible with the RMS™
remote monitoring system, which offers
comprehensive monitoring of system pa-
rameters on a Windows

®

-based network.
