Meyer Sound MPS-482HP 2-Channel Power Supply, 5-Pin Phoenix Output, 1RU - 09.285.001.01

Product Overview

The Meyer Sound MPS-482HP is a two-channel IntelligentDC power supply that delivers 48 V DC power and balanced audio to remotely self-powered Meyer Sound loudspeakers over a single composite cable. Housed in a compact 1RU, half-rack-width enclosure, it is ideal for installations requiring a small channel count or remote wall or ceiling mounting. Its fanless design operates silently, making it well suited to acoustically sensitive spaces. The unit routes two channels of balanced audio from XLR or Phoenix inputs to two 5-pin Phoenix outputs.

Product Description

The MPS-482HP expands the flexibility and cost-effectiveness of Meyer Sound's IntelligentDC remotely self-powered systems. It is designed to power compact IntelligentDC loudspeakers such as the MM-4XP, UP-4XP, UP-4slim, ULTRA-X20XP, and USW-112XP, and it can drive up to six Ashby-5C or four Ashby-8C ceiling loudspeakers, making it well suited to powering surrounds in immersive configurations. The unit receives two channels of balanced audio from two XLR 3-pin female connectors or one 6-pin Phoenix male connector and routes the audio along with DC power to its two 5-pin Phoenix male outputs. Using composite multi-conductor cables such as Belden 1502, a single cable carries both audio and 48 V DC power to the loudspeakers, eliminating wiring conduits while preserving the advantages of self-powered systems. A rear-panel link switch routes channel 1 to both outputs for convenient signal sharing, and front-panel user-replaceable fuses protect each channel output from short circuits and wiring errors. For higher channel counts, consider the Meyer Sound MPS-488X 8-Channel Power Supply, and view the complete range in our Meyer Sound collection.
