MPS-488HP EXTERNAL POWER SUPPLY
The MPS-488HP external power supply delivers DC power
and balanced audio to up to eight Meyer Sound loudspeak-
ers that require an external 48 V DC power supply.
The single-space 19-inch rack MPS-488HP can be used
with the following Meyer Sound loudspeakers:
■
MM-4XP miniature loudspeaker
■
UP-4XP ultracompact loudspeaker
■
HMS-10 surround loudspeaker.
■
MM-10XP miniature subwoofer
Powering loudspeakers from an external source eliminates
the need for wiring conduits while still preserving the advan-
tages of self-powered systems. Meyer Sound's externally
powered loudspeakers are equipped with onboard amplifi-
cation and signal-processing circuits that store DC power
and tolerate voltage drops (up to 30 percent), thereby
accommodating light-gauge cables and lengthy cable runs.
The MPS-488HP receives eight channels of balanced audio
from its XLR female Channel Inputs and routes the audio,
along with 48 V of DC power, to its eight Channel Outputs.
Channel Inputs feature toggle switches that route audio to
corresponding outputs only, or to adjacent, contiguous out-
puts. For example, Channel Input 1 can be routed to Chan-
nel Outputs 1 and 2 and Channel Input 3 can be routed to
Channel Outputs 3 and 4. Another example would be to
route Channel Input 1 to Channel Outputs 1–4 and Channel
Input 5 to Channel Outputs 5–8.
The power supply’s eight Channel Outputs are equipped with
sophisticated microprocessor-controlled current limiting that
protects each channel from short circuits and unexpected
voltages. The Channel 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 mul-
