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‑10XP 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),
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
inputs to corresponding 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

1.73

[44 mm]

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
applications 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 loud‑
speaker 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.

Architect Specifications

The 48 V DC external power supply shall power a maxi‑
mum of eight loudspeakers. The switched mode, regulated
power supply shall also route up to eight channels of
balanced audio to the loudspeakers. Balanced audio shall
be received from eight XLR female connectors. Channel
outputs shall be either Phoenix 5‑pin male or EN3 5‑pin
female connectors and deliver both DC power and bal‑
anced audio to the loudspeakers on a single composite
cable.

Audio inputs shall be routed to corresponding channel

outputs, as well as to adjacent channel outputs, with rear
panel link switches.

Front panel LEDs shall provide feedback on output voltage
and load current for each channel. Each output channel
shall be equipped with microprocessor‑controlled current
limiting that protects the channels from short circuits and
unexpected voltages.

The external power supply shall be available with
Meyer Sound's RMS remote monitoring system, providing

loudspeaker muting and monitoring of output voltage and
load current from a host computer.

The unit shall be housed in a one‑space, standard 19‑inch
rack mount cabinet, measuring 13.57" (344.78 mm) in
depth, and weighing just 15.5 lbs (16.6 kg). Its AC inlet shall
be a PowerCon locking connector to prevent unwanted
power disconnections.

The external power supply shall be the Meyer Sound
MPS‑488HP.
