Meyer Sound’s UPJunior ultracompact VariO loudspeaker brings the sonic signature, versatile rigging, and extraordinary power-to-size ratio of the UPJ-1P to a smaller package. The UPJunior combines the advantages of a self-powered system with the placement and arraying flexibility afforded by a VariO rotatable horn.

Though remarkably compact and lightweight, the UPJunior delivers a robust peak power output of 126 dB SPL at 1 meter, making it suitable for use as either a single, primary loudspeaker or within multicabinet horizontal and vertical arrays. Applications include AV presentations; small- to medium-sized main sound reinforcement systems; fill, delay, and effects systems; under-balcony coverage; and distributed systems.

The UPJunior was bred for flexibility, whether oriented vertically or horizontally. The VariO horn allows quick rotation to provide an 80-degree by 50-degree coverage pattern in either the horizontal or vertical plane. In size, weight, and output, the UPJunior integrates seamlessly with the UltraSeries UPM and UPJ loudspeakers.

The UPJunior’s low-mid frequency section employs an 8-inch neodymium magnet cone driver, while the high-frequency section utilizes an efficient 0.75-inch exit, 2-inch diaphragm compression driver. Both drivers are designed and manufactured by Meyer Sound in Berkeley, Calif. The cabinet incorporates aluminum end plates that provide unprecedented mounting, flying, and arraying flexibility. Strategically placed metric M8 threaded points allow simple mounting using either eyebolts or third-party pole assemblies.

The optional RMS module allows comprehensive monitoring of all key system parameters from a Windows-based computer. Other options include weather protection and custom color finishes for applications requiring specific cosmetics.

As a Meyer Sound self-powered loudspeaker, the UPJunior incorporates a proprietary two-channel, class AB/bridged power amplifier and sophisticated control circuitry housed within the cabinet, dramatically simplifying setup and installation. The UPJunior’s on-board amplifier delivers 300 watts of total burst power.

The UPJunior's 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 the UPJunior’s rear panel.

• No amplifier racks
• No heavy gauge loudspeaker cables
• Simplified setup or installation and reduced costs
• Enhanced reliability and flexibility

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’s RMS remote monitoring system interface may be optionally fitted, allowing engineers to monitor and troubleshoot an entire UPJunior system from a remote Windows-based computer.
