The Meyer MPS-488HP Power Supply is just one part of many loudspeaker systems in our rental inventory.

The MPS-488HP IntelligentDC power supply delivers power and balanced audio to up to eight Meyer Sound loudspeakers that require an external DC power supply. The single-space 19-inch rack MPS-488HP can be used with a number of products that feature IntelligentDC technology, such as: the UP-4XP ultracompact loudspeaker, MM-4XP miniature loudspeaker, MM-10KP miniature subwoofer, and HMS-10 surround loudspeaker.

Meyer Sound’s externally powered loudspeakers are equipped with onboard amplification and signal-processing circuits that store DC power and tolerate voltage drops (up to 30 percent), therby 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-488HP receives eight channels of balanced audio from its XLR female input connectors and routs the audio, along with DC power, to its eight output connectors. Input channels feature toggle switches that route inputs to correstponding channel outputs only, or to adjacent, contiguous channel outputs. For example, channel input 1 can be routed to channel outputs 1 and 2 and channel input 3 can be routed to channel outputs 3 and 4. Another example is to route channel input 1 to channel outputs 1-4 and channel input 5 to channel outputs 5-8. You can also simply route all eight channel inputs in parallel to their corresponding channel outputs.

The MPS-488HP’s eight channel outputs are equipped with sophisticated microprocessor-controlled current limiting that protects each channel from short circuits and unexpected voltages. The power supply’s outputs are available as either Phoenix 5-pin male connectors on the MPS-488HPp model, or Switchcraft EN3 5-pin female connectors on the MPS-488HPe model. 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-488HP to the loudspeakers. Longer cable lengths are possible for moderate application that don’t drive the loudspeakers to maximum output, as well as for installations with heavier wire gauges.

The unit’s front panel has two LEDs per channel output that provide useful feedback on the status of the system. The blue voltage LEDs indicate when voltage is present for each channel output. The green load current LEDs indicate when a loudspeaker is connected to a channel output, glow brighter as the signal level increases, and blink when a short circuit is encountered.

Available as a factory-installed option is the RMS remote monitoring system module, which provides loudspeaker muting and monitoring of output voltage and load current parameters from a Windows-based computer.

The Meyer MPS-488HP has the following features:

  • Power multiple Meyer Sound loudspeakers that require an external IntelligentDC power supply
  • Route DC power and balanced audio to loudspeakers with single, composite cables
  • Channel outputs available as either Phoenix 5-pin male or EN3 5-pin female
  • Front panel LEDs provide system feedback on voltage and load current levels
  • Remote monitoring of output voltage and load current parameters with RMS (a factory-installed option)


  • Portable and compact systems that employ MM-10XPs, MM-4XPs, MM-4XPDs, and UP-4XPs
  • Cinema installations with HMS-10 surround loudspeakers
