Electro-Voice and Dynacord have launched the LML-1 module, which enables real-time monitoring of loudspeakers within Hi-Z sound reinforcement systems.

With the LML-1 (Loudspeaker Measuring Load), it is now possible – even in large installation applications such as stadiums or shopping centres – for smaller 100-Volt loudspeakers in entrance areas, lobbies or passageways to be driven by multi-channel amplifiers from Electro-Voice or Dynacord, and supervised using IRIS-Net software.

This combination offers basic supervision of loudspeaker lines, in 100-Volt direct drive operation, within an overall project featuring both pro audio and commercial sound components.

The LML-1 is connected to the end of the loudspeaker line and powered using an inaudible pilot tone to provide a stable load condition. The load can then be measured using the existing load supervision functions of the Electro-Voice CPS and Dynacord DSA series amplifiers. The LML-1 is supplied in quantities of four pieces.

An increasing number of modern sound reinforcement systems require real-time monitoring of the loudspeaker lines. The Electro-Voice CPS and Dynacord DSA multi-channel amps already provide 100-Volt-line direct drive operation for these types of loudspeaker circuits, but in the past supervision of Hi-Z lines was not practical due to the high impedance characteristics of the load.
