CHAPTER 3
The M1D and M1D-Sub loudspeakers are fitted standard
with an RMS communication module installed in the ampli-
fier. RMS is a real-time networked monitoring system that
connects Meyer Sound self-powered loudspeakers with
a Windows-based PC at the sound mix position or other
desired remote 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 func-
tions.
The M1D and M1D-Sub loudspeakers are shipped
with these functions disabled. 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 loud-
speaker volume or AC power.
Loudspeakers are identified on the network by Node Names
assigned during a one-time “commission” (Figure 3.1) into
the RMS database that resides on your computer (as a part
of the software).
Figure 3.1. Commissioning an M1D loudspeaker using RMS
This information is permanently stored within each RMS
communication module and in the computer RMS database
unless you modify it. Speaker Titles can be changed at any
time, allowing you to customize how you view the data. In
addition, any M1D or M1D-Sub loudspeaker can be physi-
cally identified from RMS software by activating the Wink
function – a Wink LED will turn on the RMS communication
module that corresponds to its Node Name.
M1Ds and M1D-Sub loudspeakers are identified using the
RMS software by activating the “service” function; an icon
will show up on the RMS screen corresponding to its Node
Name (Figure 3.2). This makes verifying Speaker Titles and
speaker field labels easy, using the Wink or Service Button
commands.

NOTE: With RMS version 4.5 or higher, if the
loudspeaker's amplifier heatsink tempera-
ture exceeds 75° C (167° F), the user panel On/
Temp LED will turn red, while the loudspeaker icon
in the RMS host software will respond by displaying
yellow — indicating that the loudspeaker is run-
ning hot, but still within safe operating limits. If the
color in the RMS host software changes to red, then
the loudspeaker is operating above its 98º C (212°
F) maximum safe operating temperature. Should
such conditions occur, check to ensure that the
cabinet is properly ventilated and/or decrease the
loudspeaker’s audio output signal immediately.
UNDERSTANDING THE RMS USER PANEL
The RMS user panel has three LEDs and two buttons (Fig-
ure 3.3). The following sections describe their functions.
