Meyer MPS-488p Power Supply for MM-4XP
This is the external power supply for Meyer's MM-4XP loudspeaker system. The single-space 19-inch rack unit receives eight channels of balanced audio from its XLR female inputs and routes the audio, along with 48 V of DC power, to its eight Channel Outputs. The outputs — equipped with either Phoenix 5-pin male connectors on the MPS-488P model, or EN3 5-pin female connectors on the MPS-488E model — can deliver DC power to the MM-4XP loudspeakers at cable lengths of up to 300 feet 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 to the MM-4XP. Longer cable lengths are possible for moderate applications that don't drive the loudspeakers to maximum output, or for installations with heavier wire gauges.
On the MPS-488 front panel, two LEDs per output channel provide useful feedback on the status of the system. The Voltage LEDs indicate when voltage is present for each output channel, while the Load Current LEDs indicate when a loudspeaker is connected to an output and glow brighter as
the signal level increases.
