CHAPTER 1: INTRODUCTION

The UPQ-1P is designed to be used as the main system in
small to mid-sized venues or integrate smoothly and easily
with other Meyer Sound products as centerfill or sidefills in
larger applications.
UPQ-1P loudspeakers are available in custom color finishes,
allowing them to blend in with any environment. A weather-
protected version with wood-treated enclosures and rain
hood is also available to safeguard the rear of the loud-
speaker and connectors from the elements.
ADVANCED UPQ TECHNOLOGY
The UPQ-1P loudspeaker is a self-powered, two-way
design featuring drivers designed and manufactured at
Meyer Sound’s Berkeley, California, factory.
The low section features a high-power, neodymium-magnet,
15-inch cone driver with 4-inch voice coil, created to meet
the power requirements of the system. The driver is a propri-
etary design employing neodymium magnets for higher effi-
ciency and power handling with reduced weight. The high-
frequency section uses a 1.5-inch exit, 4-inch diaphragm
compression driver with a neodymium magnet, powered by
a dedicated amplifier channel. The output of the high-fre-
quency driver is coupled to a constant-Q horn that provides
80-degree horizontal by 50-degree vertical coverage (-6 dB
points).
INTEGRATED AMPLIFIER AND PROCESSING
A self-powered loudspeaker, the UPQ-1P incorporates a
high-power, 2-channel, class AB/H power amplifier and
sophisticated control circuitry housed within the cabinet,
dramatically simplifying setup and installation. Supply power
distribution to the system, connect a line level signal, and it’s
ready — leaving you to focus on design implementation
instead of installation.
The UPQ-1P loudspeaker’s on-board amplifier delivers 1275
watts total burst power (2550 watts peak). The convection-
cooled amplifier utilizes Meyer Sound’s proprietary Quiet-
Cool™ fan technology. The QuietCool fan will only turn on at
high audio levels to prevent overheating under extreme
usage conditions and includes dedicated limiters to protect
and extend the life of the drivers at very high levels and pre-
vent severe non-linear circumstances.
This modular, field-replaceable amplifier/processing pack-
age also incorporates Meyer Sound’s Intelligent AC™ power
supply, which automatically adjusts for any line voltage
worldwide and provides both soft turn-on and transient pro-
tection. The UPQ amplifier is compatible with the optional
Meyer Sound’s RMS™ remote monitoring system, which
offers comprehensive monitoring of system parameters on a
Windows
®
-based network.
NOTE: In order to use RMS, you will need
Meyer Sound’s optional RMS software, inter-
face card, and a PC running Windows
®
2000/XP or
higher.
NOTE: Complete acoustical and electrical
specifications are covered in Appendix B.
