Description

The two-channel MPS-482HP Power Supply with audio and 48 V 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 MPS-482HP Wall Bracket). Rack mounting one or two MPS-482HPs in one standard 19-inch, 2RU rack space is also possible with the optional MPS-482HP 2RU 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, UP-4slim, ULTRA‑X20XP and USW-112XP. 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 male connector and routes the audio, along with DC power, to its two Phoenix 5-pin male output connectors. Front panel user‑replaceable 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 300 feet (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 input channel 1 to both outputs. 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 MPS‑482HP 2RU Tray supports mounting of one or two power supplies in a standard EIA 19-inch wide, 2RU rack. The MPS482HP Wall Bracket enables mounting of one MPS-482HP Power Supply remotely on a ceiling, wall or pole (using a third-party pole mount).
