The UPJunior-XP, with IntelligentDC technology, offers the same sonic signature, robust peak power output, and rotatable VariO horn as the UPJunior but with the added flexibility of external DC power and lengthy cable runs without AC conduits. The UPJunior-XP was designed for flexibility. With its extraordinary size-to- power ratio and generous rigging options, the ultracompact UPJunior-XP is well suited for use as a single, primary loudspeaker or as part of multicabinet horizontal or vertical arrays. Applications include AV presentations, small- to medium-sized sound reinforcement systems, fill, delay, effects, and under-balcony coverage. The loudspeaker's 80-degree by 50-degree VariO horn is easily rotated to obtain optimum horizontal or vertical coverage for any installation.

Designed and manufactured at Meyer Sound's factory in Berkeley, California, the UPJunior-XP's transducers include one 8-inch cone driver and one 2-inch diaphragm compression driver. The proprietary drivers are powered by an onboard 2-channel, class D power amplifier that delivers 300 W of total burst power.

With IntelligentDC technology, the UPJunior-XP receives DC power and balanced audio from a single loudspeaker connector, available as Phoenix™ 5-pin male, sealed SwitchCraft® EN3™ 5-pin male, or sealed ECO-M 7-pin male. Powering the unit from an external source eliminates the need for wiring conduits while still preserving the advantages of self-powered systems. The UPJunior-XP's amplifier and signal- processing circuits store DC power and tolerate voltage drops, thereby accommodating light- gauge cables and lengthy cable runs.

The UPJunior-XP requires an external MPS-488HP IntelligentDC power supply. The single-space 19- inch rack unit distributes DC power and balanced audio to up to eight UPJunior-XP loudspeakers, or other Meyer Sound IntelligentDC loudspeakers.

Composite multiconductor cables, such as Belden® 1502 or equivalent, can deliver both DC power and balanced audio to loudspeakers at cable lengths up to 150 feet with just 1 dB of loss in peak SPL using 18 AWG wire. Longer cable runs are possible with heavier gauges. Meyer Sound's RMS remote monitoring system is optionally available for the MPS-488HP.

The UPJunior-XP cabinet is coated with a black textured finish and includes heavy-duty, corrosion-resistant 6061-T6 aluminum end plates with threaded M8 attachment points for basic eyebolt rigging and third-party pole assemblies. QuickFly® rigging options include the MAAM-UPJunior array adapter (also made from 6061-T6 aluminum), MUB-UPJunior U-bracket, and MYA-UPJunior mounting yoke assembly. Other options include weather protection and custom colors for fixed installations and installations with specific cosmetic requirements.
