The two-channel MPS-482HP power supply with audio and 48V
DC greatly expands the flexibility and cost-effectiveness of Meyer
Sound’s exclusive IntelligentDC™ remotely self-powered systems.
Housed in a rugged, compact, 1RU, half-rack-width enclosure,
the MPS-482HP is ideal for applications requiring a small channel
count or the capability for mounting remotely on a wall or ceiling
(using the MUB-MPS482 U-bracket). Rack mounting one or two
MPS-482HPs in one standard 19-inch, 2RU rack space is also
possible with the optional RMT-MPS482 Rack Tray.
Designed to power Meyer Sound loudspeakers that feature
IntelligentDC technology, the MPS-482HP is particularly
advantageous when creating two-channel systems with compact
loudspeakers, such as the MM-4XP, UP-4XP, and UP-4slim.
Additionally, it can power up to six Ashby-5C or four Ashby-8C
ceiling loudspeakers and is also ideal for powering surrounds in
immersive configurations.
Meyer Sound’s externally powered loudspeakers include on-board
amplification and signal-processing circuits that store DC power
and tolerate voltage drops to accommodate 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-482HP receives two channels of balanced audio from
its two XLR 3-pin female input connectors or one 6-pin Phoenix
connector and routes the audio, along with DC power, to its
two Phoenix 5-pin male output connectors. Front panel userreplaceable fuses protect the MPS-482HP’s two channel outputs
from short circuits and wiring errors.
The use of composite multi-conductor cables (such as Belden®
1502) allows a single cable to carry both audio and DC power from
the MPS-482HP to the loudspeakers. Outputs can deliver DC
power to loudspeakers at cable lengths up to 150 feet or 300feet
(depending on the loudspeaker model) with just 1 dB of loss in
peak SPL using 18 AWG wire. Longer cable lengths are possible
for moderate applications that do not drive the loudspeakers to
maximum output, as well as for installations with heavier gauge
wires.
The MPS-482HP rear panel features a toggle switch that routes
the signal from channel 1 to channel 2. This linking capability is
convenient for sending the same signal to both outputs without
the need for additional cabling.
The unit’s front panel has three LEDs per channel output to
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 and glow brighter as the signal
level increases. The red LEDs indicate a blown or open fuse on
that channel.
Two optional accessories provide additional flexibility. The
RMT-MPS-482 Rack Mount Tray supports mounting of one or two
power supplies in a standard EIA 19-inch wide, 2RU rack. The
MUB-MPS-482 U-Bracket enables mounting of one MPS-482HP
power supply remotely on a ceiling, wall or other surface.
FEATURES AND BENEFITS

• Works as a supplemental power supply to the MPS-488HP power supply for applications requiring more than eight and less than sixteen channels
• Enables remote mounting of power supply and routing of DC power and balanced audio to loudspeakers with composite cables
• Fanless design operates quietly in acoustically sensitive environments
• Enclosure includes threads for mounting in accessories as well as cable-routing, strain-relief tabs
• Front panel LEDs provide system feedback on voltage status, load current levels, and fuse status
APPLICATIONS
• Conference rooms
• Theaters
• Constellation systems
• Cinema and television post-production facilities
• High-end private theaters
• Supplemental power supply for any IntelligentDC loudspeaker system
ACCESSORIES
RMT-MPS-482 Rack Mount Tray: Allows mounting of one or two power supplies on a standard EIA 19-inch wide rack. The 2 RU tray height facilitates
cooling of the MPS-482HP power supply, as the area above the unit is empty. Includes one tray face cover for unused slot.
MUB-MPS-482 U-Bracket: Enables mounting of one MPS-482HP power supply remotely on a ceiling, wall or other surface. Ability to hang power
supply below bracket or mount power supply on top; bracket above power supply orientation provides space for cable routing; accommodates M6
fasteners.
