The UPM-1XP 48 V DC is a compact, wide-coverage loudspeaker and the low-voltage version of the UPM-1P three-way loudspeaker. It is capable of 123dB peak SPL over an operating frequency range of 75 Hz to 20 kHz.

UPJunior-XP 48 V DC ultracompact VariO loudspeaker combines is a self-powered unit with the VariO constant directivity horn. The 80 x 50-degree pattern can be changed quickly from horizontal to vertical orientation. Power output is 126dB peak over a 70 Hz to 20 kHz operating range.

The UMS-1XP 48 V DC compact subwoofer extends low-voltage system response to an operating frequency range of 25 Hz – 160 Hz and a peak SPL of 127 dB at 1 meter. Visceral impact is provided by dual 10-inch cone drivers.

Meyer Sound self-powered low-voltage systems incorporate on-board amplifiers and signal processing. The UPM-1XP, UPJunior-XP, and UMS-1XP draw DC power from a remote rack-mount power supply. The loudspeakers receive 48-volt DC power and balanced audio via a five-pin connector. These systems can be installed using Class 2 wiring without using a conduit.

Amplifier circuits are designed to store power for peak demands, allowing the flexibility of lengthy cable runs while still preserving the advantages of self-powered systems. RMS remote monitoring system is available for monitoring of critical loudspeaker and amplifier parameters as well as individual loudspeaker muting.
