MM-10XP Subwoofer
The MM-10XP is powered by an external 48 V DC power supply (see meyersound.com/product/mps for details), eliminating the need for wiring conduits while still preserving the advantages of self-powered loudspeaker systems. The unit's onboard amplifier and signal-processing circuits were designed to store DC power and tolerate voltage drops, thereby accommodating light-gauge cables and lengthy cable runs. The MM-10XP is available with either a Phoenix™ 5-pin male or SwitchCraft® EN3™ male connector for receiving balanced audio and DC power.
Meyer Sound IntelligentDC External Power Supply
MM-10XPs require a Meyer Sound IntelligentDC external power supply. The MPS-488HP single-space 19-inch rack unit receives balanced audio from its XLR female inputs and routes the audio, along with 48 V of DC power, to its channel outputs. The channel outputs—equipped with either Phoenix 5-pin male connectors (MPS-488HPP) or EN3 5-pin female connectors (MPS-488HPE)—can deliver DC power to up to eight MM-10XP subwoofers. The smaller, 1RU,
half-rack MPS-482HP unit provides power and audio to two loudspeakers via its two Phoenix 5-pin male connectors.

Cable lengths up to 150 feet for DC power are possible when using 18-AWG wire, with just 1 dB of loss in peak SPL. Longer cable runs are possible for moderate applications that do not drive the subwoofers to maximum output, or for installations with heavier wire gauges.
The use of composite multiconductor cables (such as Belden® 1502) allows a single cable to carry both DC power and balanced audio to the MM-10XPs.
