The self-powered UPJunior combines clear, powerful sound with a rotatable horn, a

very small footprint, and a full spectrum of mounting and rigging options to provide a

utility loudspeaker that’s ready to go anywhere you need it.

Though remarkably compact and lightweight (only 28 pounds/12.7 kilograms), UPJunior

delivers a robust peak power output of 126 dB SPL at 1 meter, making it suitable

for use either as a single, primary loudspeaker or within multicabinet horizontal and

vertical arrays. Applications include AV presentations and small- to medium-size main

sound reinforcement systems, as well as in fill, delay, effects, under-balcony coverage,

and distributed systems. UPJunior even makes an excellent small stage monitor when

used with the optional MAAM-UPJunior array adapter plates. In larger systems, UPJunior

is ideal for providing sound to areas not reached by the main system, or perhaps to

immerse an audience in a multichannel sound field.

UPJunior

UltraCompact VariO loudspeaker

The UPJunior was developed based on the

success and popularity of UPJ-1P. By putting

the same powerful technology into a smaller

package, we’re giving our customers another

tool that can be used in many different

applications where its smaller profile will keep

it from obstructing sight lines and allow it to

fit into very tight spaces.” – John Meyer

“

UPJunior was designed for flexibility. Whether oriented vertically or horizontally, its VariO

horn allows quick rotation for obtaining the optimum horizontal and vertical coverage

patterns in any situation. With its rotatable horn, small size, and QuickFly rigging, there’s

hardly anywhere UPJunior can’t be placed.

UPJunior integrates seamlessly with other Meyer Sound products, including the UltraSeries,

UPM-1P, UPM-2P, UPJ-1P, and UPA-1P loudspeakers. For smaller, full-range systems,

UPJunior works well with the UMS-1P or M1D-Sub ultracompact subwoofers. In applications

requiring greater low-frequency support, the 600-HP high-power subwoofer can be used.

It’s a sizable list of capabilities for a small speaker. But that’s UPJunior: the small loudspeaker

that makes a big difference.

UPJunior

Meyer Sound’s VariO horn can be easily rotated in the field by removing only eight screws. The ability to

reconfigure UPJunior’s coverage lets users get the best coverage in nearly any situation.

COMPONENTS

UPJunior is a two-way system employing components designed and manufactured by Meyer Sound in Berkeley,

Calif. Meyer Sound’s rigorous quality assurance guarantees the performance and consistency of each UPJunior.

UPJunior’s low/mid-frequency section employs an 8-inch neodymium magnet cone driver with a 1.5-inch voice

coil, while the high-frequency section utilizes an efficient 0.75-inch exit, 2-inch diaphragm compression driver.

The high-frequency driver is mounted on a rotatable, 80-degree-by-50-degree VariO horn for maximum

flexibility in obtaining desired coverage.

THE SELF-POWERED ADVANTAGE

Having manufactured self-powered sound reinforcement loudspeakers

since 1995, Meyer Sound has pioneered and refined this technology to

produce systems that are powerful and reliable. Self-powered systems

eliminate heavy, expensive, amplifier racks and large loudspeaker

cables, thereby lowering costs. With no need to calibrate gain and

crossover settings, self-powered systems are easy to use and go from

the truck to fully rigged and back in minutes.

UPJunior incorporates a proprietary two-channel, class AB/bridged

power amplifier and sophisticated control circuitry housed within the

cabinet, dramatically simplifying setup and installation. UPJunior’s

integrated amplifier delivers 300 watts of total burst power, while

the onboard processing includes an electronic crossover, phase and

frequency response correction filters, and driver protection circuitry,

including peak and rms limiters on each channel that prevent driver

overexcursion and regulate the temperature of the voice coil. Limiter

activity is easy to monitor with high-color limit LEDs on UPJunior’s

rear panel.

The optional RMS remote monitoring system module continuously

reports the status of all key system parameters from a remote

computer running Windows OS. Other options for UPJunior include

weather protection and custom color finishes for applications requiring

specific cosmetics.

The modular, field-replaceable amplifier/processing package 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 protection.

Meyer Sound self-

powered systems

enclose their

complex crossovers,

protection circuitry,

and power amplifiers

entirely within the

enclosure, resulting

in the greatest ease

of setup and use.

QUICKFLY RIGGING PUTS UPJUNIOR WHEREVER YOU NEED IT

Meyer Sound’s patented QuickFly rigging is as versatile and easy to use as the UPJunior itself. Designed for maximum safety

and strength, UPJunior’s QuickFly mounting options enable UPJunior to be used singly or in arrays of two or three, and

mounted on ceilings (such as for under-balcony applications), floors, walls, or trusses; used as a stage monitor; or, with the

use of a third-party adapter, pole mounted.

Mounting and rigging options make use of UPJunior’s integral top and bottom aluminum end plates (made of heavy duty,

high-strength, corrosion-resistant 6061-T6 aluminum) with threaded M8 attachment points.

Combining its VariO horn with its QuickFly hardware, UPJunior is capable of an unparalleled degree of utility, enabling smooth

coverage to be attained in even the trickiest situations.

MAAM-UPJunior Array Adapter Plate

The MAAM-UPJunior array adapter plate enables a variety of vertical and horizontal array configurations using two or three UPJunior

cabinets. The MAAM-UPJunior has holes for accepting eyebolts or a shackle for maximum flexibility in mounting and rigging, and

allows the separation between two cabinets in an array to be set to any angle from 10 to 80 degrees. The MAAM-UPJunior is also

used when laying the cabinet horizontally for use as a stage monitor.

MAAM-UPJunior lets UPJunior be

used as a stage monitor.

With MAAM-UPJunior, up to three

UPJunior cabinets can be arrayed

vertically or horizontally.

MAAM-UPJunior enables any angle

between 10 and 80 degrees to be set

between two UPJunior cabinets.

UPJunior

MUB-UPJunior U-bracket

The MUB-UPJunior U-bracket can be used for mounting UPJunior on floors, walls, ceilings, or truss.

MUB-UPJunior can be

suspended from truss for a

variety of fill applications.

The MUB-UPJunior allows

UPJunior to be mounted on

walls for fill or surround

applications.

UPJunior can be easily mounted

on a ceiling or floor with the

MUB-UPJunior for applications

such as under-balcony coverage.

MYA-UPJunior

Mounting Yoke Assembly

The MYA-UPJunior cradle-style mounting

yoke suspends a single UPJunior loudspeaker

and allows a wide range of horizontal and

vertical adjustment.

Pole Mounting UPJunior

UPJunior cabinets can be easily pole-mounted using a third-party adapter.

Pole mounting a single UPJunior onto a UMS-1P ultracompact subwoofer

is as simple as fitting an MPS-UMS pole stand into the integral pole mount

receptacle in the UMS-1P, then mounting a UPJunior (with third-party adapter)

onto it. Use pole mounted UPJuniors

for portable and small-scale

applications.

MEYER SOUND’S ULTRASERIES LOUDSPEAKERS

UPJunior is a member of Meyer Sound’s UltraSeries. The UltraSeries is where it all began for Meyer Sound with the introduction of the UM-1

UltraMonitor, followed shortly thereafter by the UPA-1. The UPA-1 was a milestone in sound reinforcement, leading to its being honored as

an inaugural inductee into the TECnology Hall of Fame. The trapezoidal shape of the UPA-1 cabinet was a breakthrough important enough to

be recognized by the U.S. Patent and Trademark Office, which issued Meyer Sound one of its first patents for the innovation. The trapezoidal

shape, which allows cabinets to be easily arrayed, is now standard in the industry. The UPA-1 and UM-1 were also the first processor-

controlled loudspeakers, another Meyer Sound advance that is now commonplace.

The 1997 release of the UPA-1P marked yet one more major step forward: the first high-output, self-powered system in a compact package.

The appearance of the UPA-1P spurred numerous imitations by other manufacturers, but Meyer Sound remains the only manufacturer fully

committed to self-powered systems. More than 12 years after it first pioneered self-powering, Meyer Sound’s singular experience and

substantial investment in research are clearly demonstrated in the performance and consistency of its over 40 self-powered loudspeakers.

The UPA-1P is the self-powered version

of the landmark loudspeaker that

introduced the trapezoidal cabinet and

processor control of loudspeakers.

The UPJ-1P introduced the rotatable

VariO horn and flexible mounting found

in UPJunior.

The UPM-1P is often used for fill

applications, spot coverage, and as a

main loudspeaker in small systems.
