Overview
The UPM-1XP, with IntelligentDC technology, is a compact, externally‑powered, wide‑coverage loudspeaker for professional sound reinforcement. It offers the same high sound pressure levels, low distortion, and uniform directional control as the UPM‑1P but with the added flexibility of external DC power—enabling lengthy cable runs without AC conduits. Ideal usage of the UPM-1XP is for applications requiring wide coverage in a small, inconspicuous cabinet where AC cabling is not feasible.
As a standalone loudspeaker, use the UPM‑1XP for vocal reinforcement, frontfill coverage, or delay coverage for under‑balcony applications. For full‑range systems, pair the UPM-1XP with Meyer Sound’s UMS‑1XP ultracompact subwoofer with IntelligentDC technology.
The UPM‑1XP’s high‑frequency section includes a 1‑inch metal dome tweeter on a constant‑directivity, high‑frequency horn with a 100° beamwidth. The low/mid‑frequency section includes two 5‑inch cone transducers that work in parallel at low frequencies— delivering a combined acoustic output—with one of the drivers rolling off above 320 Hz to prevent interference in the crossover region due to comb filtering effects. A three‑channel amplifier, which includes active crossover, driver protection, and frequency and phase correction circuitry, powers the proprietary drivers that Meyer Sound manufactures at its factory in Berkeley, California.
With IntelligentDC technology, the UPM‑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 UPM-1XP’s amplifier and signal‑processing circuits store DC power and tolerate voltage drops, thereby accommodating light‑gauge cables and lengthy cable runs.
The UPM-1XP requires a Meyer Sound IntelligentDC external power supply. For larger installations, the single‑space rack‑mount MPS‑488HP IntelligentDC power supply unit distributes DC power and balanced audio to up to eight UPJunior‑XP loudspeakers or other Meyer Sound IntelligentDC loudspeakers. For smaller installations, the MPS‑482HP IntelligentDC power supply offers two channels of audio and DC power. 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 gauge wires.
Meyer Sound’s RMS™ remote monitoring system, which offers comprehensive monitoring of loudspeaker parameters from a Mac® or Windows®‑based computer running Compass® control software, is optionally available for the MPS‑488HP.
Meyer Sound coats the UPM‑1XP cabinet with a slightly textured black finish and includes three threaded, recessed nut plates (3/8 in‑16 or metric M10). Optional rigging hardware includes the MYA‑UPM mounting yoke, MUB‑UPM U‑bracket, and MSA‑UPM stand adapter. Other UPM-1XP options include weather protection and custom color finishes for fixed installations and installations with specific cosmetic requirements.
