High-Performance Audio. Low-Voltage Installation. Together for the first time.

Features & Benefits


Lower distortion and wider bandwidth for significantly better music quality and voice intelligibility.

Higher SPL output for more headroom and greater throw distance. In many installations, this translates into fewer loudspeakers and more pleasant aesthetics.


Tighter, more powerful bass response down to 25 Hz with the UMS-1XP subwoofer.


Flatter frequency and phase response for more consistent performance and easier tuning of high-performance, multi- loudspeaker installations.

Greater power/performance-to-size ratio with no transformer and line losses between amplifier and speaker.



AV playback systems for museums, trade show exhibits and corporate presentations.

Foreground music and PA auxiliary systems for bars, restaurants, nightclubs, retail outlets, and cruise ships.

Ultra-compact PA systems for meeting rooms.

Front, underbalcony and spot fill in theatres, concert halls and places of worship.

For AV installations demanding the utmost in audio quality, Meyer Sound offers an innovative solution: low-voltage, self- powered systems. This exclusive technology opens up a broad range of options for system designers, consultants, integrators and contractors.

As with conventional constant-voltage solutions, these new systems can be installed without conduit*, but the loudspeakers operate on DC power from a remote rack-mount power supply, so there is no need for AC mains service — requiring Class 1 electrical conduit — at each loudspeaker location. The amplifier and signal-processing circuits store DC power for peak demands, allowing the flexibility of lengthy cable runs (without conduits) while preserving the advantages of self-powered systems. Power and balanced audio can be carried on a single multi-conductor cable terminated by a 5-pin connector. As a result, installation times and costs are reduced compared to those of conventional constant-voltage systems.

However, the audio performance is beyond comparison. In any application — from foreground music in an intimate restaurant to auxiliary systems in large performance halls — the audible superiority of Meyer Sound self-powered technology will be noticed, and appreciated.

* In North America, electrical codes identify low voltage and low current electrical wiring methods as Class 2. Europe has also adopted a unified safety standard that identifies a low voltage and low current electrical wiring as Protective Extra Low Voltage (PELV).

Connectors and Wiring

ECO-M connector

Meyer Sound low-voltage loudspeakers offer several different connector options. All can be ordered with Phoenix 5-pin plug-in connectors for quick, secure connection in any installation. In addition, many of the loudspeakers – those likely to be used in theatrical and corporate AV applications – may be ordered with the rugged EN3 circular 5-pin connector.

The UPJ-1XP, UPJunior-XP, UPM-1XP, UPM-2XP, and UMS-1XP – those well suited to outdoor applications in theme parks, themed spectaculars and open-air hospitality installations – also offer the robust and environmentally sealed and locking ECO-M 7-pin connector.

The ECO-M connector is a right-angle locking, water-tight connector that was originally designed for industrial DC power applications, yet it is also ideally suited for low-voltage self-powered loudspeakers.

ECO-M connectors have cable outlets that make it possible to fit cables with diameters between 8mm and12mm (26-16 AWG). The ECO-M connector is offered with 7 pins (two that are not used) and have screw-clamp termination, enabling users to more easily terminate connectors in the field.

In addition to the low-profile design – less than 2.5" (61mm) from the user panel -- the right-angle connectors are keyed and allow the cable exit to be rotated in multiple different positions, allowing the cable exit to match the desired orientation.

One ECO-M cable-mount connector is shipped with each loudspeaker. Please specify this cable option when ordering.
