Smart Power for Distributed Audio


MPS-488HP and MPS-482HP are the central stations of your Meyer Sound system’s IntelligentDC technology, which combines the sonic superiority of self-powered loudspeakers with the installation ease of low-voltage systems by delivering balanced audio and DC power together over composite cables. Power up to eight loudspeakers with MPS-488HP, and up to two loudspeakers with MPS-482HP.


MPS-488HP routes DC power and balanced audio to up to eight loudspeakers. Supply audio and power signals through a single connector, available as either Phoenix 5-pin or Switchcraft® EN3 5-pin. For added flexibility, toggle switches route inputs to one or more channel outputs. 


MPS-482HP sends power and audio to two speakers, for IntelligentDC systems with limited loudspeaker requirements or to supplement systems that fall between multiples of eight. Its silent, fanless operation means it can share the same acoustic space as your loudspeakers, and mounting options let you install it in a rack or remotely on a wall, ceiling, or other surface.


Front-panel LEDs provide real-time feedback on crucial data like voltage status and load current levels; MPS-488HP’s RMS option lets you monitor output voltage and load current parameters remotely on your Windows PC.


The MPS-488HP powers up to eight loudspeakers and is ideal for use with our 48 V DC IntelligentDC line, including the UP-4XP ultra-compact loudspeaker, MM-4XPminiature loudspeaker, MM-10XP miniature subwoofer, and HMS-10 cinema surround loudspeaker.


The MPS-482HP powers two loudspeakers and its applications include corporate systems, hospitality suites, home theatre, and retail. It pairs perfectly with any of Meyer Sound's IntelligentDC loudspeakers, including the MM-4XP, UP-4XP and UP-4slimmodels, or in larger installations alongside MPS-488HP units.
