Meyer Sound MJF-212ATM Manuale Utente

13

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 
performance data from every installed loudspeaker. The 
MJF-212A monitor is RMS-ready and can be upgraded by 
installing an RMS communication board 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 2–5 times per second. 

Optional loudspeaker Mute and Solo 

functions are helpful for acoustic setup or 

troubleshooting. A jumper is installed in the RMS 
communication board inside the MJF-212A amplifier 
to enable Mute and/or Solo functionality. To use 
these features, the software needs to be enabled. 

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. 

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 permanently retained on each RMS communication 
board and in the computer RMS database until you modify 
it. Loudspeaker View labels can be modified at any time, 
allowing you to customize how you view the data. 

Two-way communication between the RMS software and 
the MJF-212A monitor makes identifying and matching 
loudspeakers and icons easy. Pressing the “service” button 
on the MJF-212A loudspeaker’s RMS module will help 
quickly identify the MJF-212A in the RMS software window; 
an icon corresponding to its Node Name will appear on 
screen. In addition, clicking on the icon’s Wink command 
will turn on the LED labeled “Wink” on the MJF-212A’s RMS 
module. This way any MJF-212A can be easily identified 
from the RMS software.

When upgraded, the MJF-212A’s user panel contains an 
RMS communications module, as shown in Figure 4.3. 

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

The LEDs and buttons on the RMS 

communications module shown in Figure 

4.3 are used 

exclusively by RMS, and have no 

effect on the acoustical and/or electrical activity of 
the MJF-212A monitor — unless Mute or Solo is 
enabled at the board and from the RMS software.

The Service LED blinks every two seconds to indicate that 
the network hardware is operational, but the loudspeaker is 
not installed (commissioned) on the network.
