What Is the MPS488-HP?

The MPS-488HP is an eight-channel rackmount power supply and signal distribution unit that powers XP-series loudspeakers via a single cable. This minimizes on-site AC wiring and ensures fast, neat installations.

• Delivers 48 VDC + balanced audio over shielded CAT5 or Belden 1502

• Rack-mountable (1U)

• Features individual signal, power, and fault LEDs

• Optional remote monitoring via RMServer

The use of low-voltage audio power delivery is similar in concept to Power over Ethernet (PoE), making this system flexible and installation-friendly.
