MPS-488HP EXTERNAL POWER SUPPLY
The MPS-488HP IntelligentDC power supply delivers power
and balanced audio to up to eight Meyer Sound loudspeak-
ers that require an external DC power supply.
The 1-space rackmount MPS-488HP can be used with a
number of products that feature IntelligentDC technology,
such as: MM-4XP miniature loudspeaker, MM-10XP minia-
ture subwoofer, and HMS series surround loudspeakers.
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), thereby 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 routes the audio,
along with DC power, to its eight output connectors. Input
channels feature toggle switches that route audio to corre-
sponding outputs only, or to adjacent, contiguous outputs.
For example, channel input 1 can be routed to channel
outputs 1–2 and channel input 3 can be routed to channel
outputs 3–4. Another example would be to route channel
input 1 to channel outputs 1–4 and channel input 5 to chan-
nel outputs 5–8. All eight channel inputs can be routed 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 channel outputs are available as either
Phoenix™ 5-pin male connectors on the MPS-488HP
P
model, or SwitchCraft ® EN3™ 5-pin female connectors on
the MPS-488HP
E
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-
