INTRODUCING THE UPJ-1P COMPACT VARIO™

LOUDSPEAKER

The UPJ-1P compact VariO loudspeaker combines the
advantages of being self-powered with the placement
and arraying exibility afforded by a VariO rotatable horn.
Remarkably compact and lightweight, the UPJ-1P (Figure
i.1) produces a robust peak power output of 128 dB SPL
at 1 meter, making it suitable for use either as a primary
loudspeaker in small rooms or as a ll, delay, effects or un-
der-balcony loudspeaker in any type of large or distributed
system application.

The UPJ-1P’s low-frequency section employs a 10-inch
neodymium magnet cone driver, while the high-frequency
section utilizes a 0.75-inch exit, 3-inch diaphragm compres-
sion driver of proprietary design. The VariO horn allows
quick rotation to provide a 80° x 50° coverage pattern in ei-
ther the horizontal or the vertical plane. A two-channel class
AB power amplier with complementary MOSFET output
stages provides a total output of 300 watts for the low- and
high-frequency sections.
The UPJ-1P cabinet's end plates provide unprecedented
mounting, ying and arraying exibility, and are made of
heavy duty, high-strength, corrosion-resistant 6061-T6
aluminum. Strategically placed M8 threaded points allow
simple mounting using eyebolts or directly to third party
pole assemblies. Available QuickFly® rigging options — in-
cluding an array adapter (also made from 6061-T6 alumi-
num), yokes, and “L”-brackets — attach easily and securely
to the aluminum end plates allowing UPJ-1P to be mounted
or own, either as a single cabinet or in arrays. The optional
RMS™ remote monitoring system module allows com-
prehensive monitoring of all key system parameters on a
remote RMS host PC.
NOTE: Read this entire manual carefully
before conguring and deploying a UPJ-1P
system. In particular, pay careful attention to the
sections about safety issues.
