Meyer Sound M'elodie, Operating Instructions Manual

15

CHAPTER 4

RMS is a real-time monitoring system that connects Meyer 
Sound self-powered loudspeakers with a Windows-based 
PC at the sound mix position or other location. Optional 
RMS software delivers extensive status and system perfor-
mance data from every installed loudspeaker. M’elodie is 
RMS-ready and fitted standard with an RMS communica-
tion board installed in its user panel. 

RMS allows the monitoring of amplifier voltages, limiting 
activity, power output, temperature, driver status, warning 
alerts, and other key data for up to 62 loudspeakers without 
a network repeater. Data is updated two to five times per 
second. 

NOTE: 

Optional loudspeaker Mute and Solo 

functions are helpful for acoustic setup or 

troubleshooting. A jumper is installed in the RMS 
communication board inside the M’elodie ampli-
fier to enable Mute and/or Solo functionality. To use 
these features, the software needs to be enabled. 

NOTE: 

The RMS software allows you to 

disable Mute and Solo functions to eliminate 

any chance of an operator error (a muting error, for 
example). However, these functions can be disabled 
permanently by removing the jumper in the RMS 
communication board. 

NOTE: 

RMS does not control AC power. 

Loudspeakers are identified on the network by Node Names 
assigned during a one-time “commission” into the RMS 
database that resides on your computer (as a part of the 
software), as shown in Figure 4.1. This information is per-
manently retained on each RMS communication board and 
in the computer RMS database until you modify it. Loud-
speaker View labels can be modified at any time, allowing 
you to customize how you view the data.

Commissioning a M’elodie loudspeaker using RMS.

Back and forth communication between the RMS software 
and the M’elodie makes identifying and matching loudspeak-
ers and icons easy. Pressing the “service” button on the 
M’elodie loudspeaker’s RMS module will help quickly identify 
the M’elodie in the RMS software window; an icon corre-
sponding to its Node Name will appear on screen. In addi-
tion, clicking on the icon’s Wink command will turn on the 
LED labeled “Wink” on the M’elodie’s RMS module. This way 
any M’elodie can be easily identified from the RMS software.

The RMS communications module

The RMS module has three LEDs and two buttons. Their 
functions are described on the following page.

NOTE: 

The LEDs and buttons on RMS communi-

cation board shown in Figure 4.3 are used 

exclu-

sively

 by RMS, and have no effect on the acoustical 

and/or electrical activity of the M’elodie loudspeaker 
itself — unless Mute or Solo is enabled at the board 
and from the RMS software.
