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

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.

The two-channel MPS-482HP power supply with audio and 48V DC greatly expands the flexibility and cost-effectiveness of Meyer Sound’s exclusive IntelligentDC™ remotely self-powered systems. Housed in a rugged, compact, 1RU, half-rack-width enclosure, the MPS-482HP is ideal for applications requiring a small channel count or the capability for mounting remotely on a wall or ceiling (using the MUB-MPS482 U-bracket). Rack mounting one or two MPS-482HPs in one standard 19-inch, 2RU rack space is also possible with the optional RMT-MPS482 Rack Tray.

Designed to power Meyer Sound loudspeakers that feature IntelligentDC technology, the MPS-482HP is particularly advantageous when creating two-channel systems with compact loudspeakers, such as the MM-4XP, UP-4XP, and UP-4slim. 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.

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-4slim models, or in larger installations alongside MPS-488HP units.
