Operating Instructions — MPS-482HP Power Supply
The two-channel IntelligentDC MPS-482HP Power Supply delivers 48 V DC and balanced audio to Meyer Sound IntelligentDC loudspeakers that require an external DC power supply.

Designed to use with any Meyer Sound loudspeaker that features IntelligentDC technology, the half-space rack-mount MPS-482HP Power Supply is particularly advantageous when creating two-channel systems with compact loudspeakers, such as the MM-4XP, MM-10XP, UP-4XP, UP-4slim, ULTRA-X20XP, and USW-112XP.
Additionally, it can power up to six Ashby-5C or four Ashby-8C ceiling loudspeakers and is also ideal for powering surrounds in immersive configurations.
Caution
Only connect to 48 V DC Meyer Sound Powered Speakers. See the labeling on the bottom of the unit for a list of compatible speakers or contact Meyer Sound.
Meyer Sound's externally powered loudspeakers include on-board amplification and signal-processing circuits that store DC power and tolerate voltage drops (up to 30 percent) to accommodating light-gauge cables and lengthy cable runs. Powering loudspeakers from an external source eliminates the need for wiring conduits while still preserving the advantages of self-powered systems.
The MPS-482HP Power Supply receives two channels of balanced audio from its two XLR 3-pin female input connectors or one 6-pin Phoenix™ male input connector and routes the audio, along with DC power, to its two Phoenix 5-pin male output connectors. Front panel user-replaceable fuses protect the MPS-482HP Power Supply’s two channel outputs from short circuits and wiring errors. The rear panel features a toggle switch that routes the signal from channel 1 to both outputs (to send the same signal to both outputs without additional cabling).
Outputs can deliver DC power to loudspeakers at cable lengths up to 150 feet or 300 feet (depending on the loudspeaker model) with just 1 dB of loss in peak SPL using 18 AWG wire. The use of composite multiconductor cables (such as Belden® 1502) allows a single cable to carry both audio and DC power from the MPS-482HP Power Supply to the loudspeakers. Longer cable lengths are possible for moderate applications that do not drive the loudspeakers to maximum output, as well as for installations with heavier gauge wires.
