The UPJ-1XP, with IntelligentDC technology, offers the same sonic signature, robust peak power output, and rotatable VariO horn as the UPJ-1P but with the added flexibility of external DC power and lengthy cable runs without AC conduits. The UPJ-1XP was designed for flexibility. With its extraordinary size-to-power ratio and generous rigging options, the compact UPJ-1XP 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 distributed systems. 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 UPJ-1XP's transducers include one 10-inch cone driver and one 3-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 UPJ-1XP 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 UPJ-1XP's amplifier and signal- processing circuits store DC power and tolerate voltage drops, thereby accommodating light- gauge cables and lengthy cable runs.

The UPJ-1XP 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 UPJ-1XP 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 UPJ-1XP 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-UPJ array adapter (also made from 6061-T6 aluminum), MUB-UPJ U-bracket, and MYA-UPJ mounting yoke assembly. Cabinets are available from the factory without handles. Other options include weather protection and custom colors for fixed installations and installations with specific cosmetic requirements.
