CHAPTER 4
The RMS communication module is standard in 600-HP
subwoofers with the MRF-600 rigging frame installed and is
optional in the other models, making use of Meyer Sound’s
RMS remote monitoring system. RMS is a real-time net-
worked monitoring system that connects Meyer Sound self-
powered loudspeakers with a Windows-based PC at the
sound mix position or other desired location. Optional RMS
software delivers extensive status and system performance
data directly to you from every installed loudspeaker.
RMS allows you to monitor amplifier voltages, limiting
activity, power output, temperature, fan and driver status,
warning alerts, and other key data for up to 62 loudspeak-
ers without a network repeater; data is updated two to five
times per second.
NOTE:
Optional Loudspeaker Mute and
Solo functions, helpful for acoustic setup or
troubleshooting, are also available. A jumper must
be installed in the RMS communication module
in order to enable Mute and/or Solo functionality;
the software also needs to be enabled for these
functions.
If your 600-HP is shipped fitted with an RMS communica-
tion module, Loudspeaker Mute and Solo functions are
disabled by default. Once enabled, the jumper(s) can still
be removed to eliminate any chance of an operator error (a
muting error, for example) during a performance, and both
functions can be controlled by software commands in any
case. Also note that RMS does not control loudspeaker
volume or AC power.
Loudspeakers are identified on the network by Node Names
assigned during a one-time “commission” (Figure 4.1) into
the RMS database that resides on your computer (as a part
of the software).
Figure 4.1.
Commissioning a loudspeaker using RMS
This information is permanently retained on each RMS com-
munication module and in the computer RMS database un-
less you modify it. Speaker View labels can be modified at
any time, allowing you to customize how you view the data.
Pressing the “service” button on the 600-HP loudspeaker’s
RMS module will help quickly identify the 600-HP 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 600-HP loudspeaker’s RMS module. This back and
forth communication between the software and the loud-
speaker makes identifying loudspeakers and icons easy.

UNDERSTANDING THE RMS COMMUNICATION
MODULE’S USER PANEL
The RMS communication module's user panel, shown in
Figure 4.3, has three LEDs and two buttons. The following
sections describe their functions.
Figure 4.3. The RMS user panel
Service LED (Red)
When blinking once every two seconds, the Service LED
indicates that the network hardware is operational, but the
loudspeaker is not installed (commissioned) on the network.
When a loudspeaker has been installed on the network,
the Service LED will be unlit and the Activity LED will flash
continuously.
NOTE:
When continuously lit, the Service
LED indicates that the loudspeaker has had
a local RMS hardware failure. In this case, the RMS
communication module may be damaged and you
should contact Meyer Sound Technical support.
