Cinema installations with HMS-10 surround loudspeakers

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 14 and channel input 5 to channel outputs 58. 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 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 RMSTM remote monitoring system module, which provides loudspeaker muting and monitoring of output voltage and load current parameters from a Windows®-based computer.


MPS-481 DC Power Supply for MM-4XP

The MPS-481 external power supply provides DC power for a single MM-4XP loudspeaker. The MM-4XP is a self powered, miniature loudspeaker designed for high-quality distributed systems. Housed in a compact aluminum enclosure, the MM-4XP is especially suitable for installations involving space limitations and visibility concerns.

The MPS Power Supplies are the required method of powering MM-4XP loudspeaker systems. The compact MPS-481 is designed for powering single loudspeakers, while the rackmount 8-channel MPS-488HP IntelligentDC power supply is ideal for larger installations with multiple loudspeakers. The MPS-481 includes a 10-foot cable that receives balanced audio from its XLR female input connector and routes the audio, along with DC power from the power supply to a Switchcraft® EN3TM 5-pin connector that attaches to the MM-4XP input connector.

The MPS-481 can deliver DC power to the MM-4XP loudspeaker at cable lengths of up to 300 feet with just 1 dB of loss in 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-481 to the loudspeaker. 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.

Amplifier and signal processing circuits for the MM-4XP are designed to tolerate voltage drops up to 30 percent, thereby accommodating light-gauge cables and long cable runs. Internal energy storage circuits for the MM-4XP minimize the system's peak-to-average current demands, ensuring efficient use of the MPS-481's DC output.

The MPS-481 includes a bracket for mounting the power supply on walls and ceilings.

* The MPS-481 power supply is only compatible with MM-4XP loudspeakers and can power a maximum of one unit. The MPS-481 is not compatible with other larger loudspeakers with IntelligentDC technology, like the UP-4XP, HMS-10, and MM-10XP models.
