Service manual

If you do not hear the relays click verify the AC line voltage by measuring the

Connections:
With the User Panel removed from the amp chassis, disconnect both the green

RMS (Remote Monitoring System) “Communications Board” (Optional):
The Remote Monitoring System (RMSª) is an optional real-time monitoring
system which connects Meyer Sound self powered speakers with a PC or Mac at
the sound mix position or other location. RMS software delivers extensive status
and system performance data directly to the operator from every installed
speaker.
RMS displays include amplifier voltages, limiting activity, power output,
temperature, fan and driver status, warning alerts, and other key data.
Interconnection of the network computer and speakers is straightforward, using
twisted pair cable and simple connectors. The network plugs in to the connectors
on the Network Board located at the rear of the computer, and on the User Panel
at the rear of each speaker.
Control Board:
The control board contains the frequency and phase response correction circuitry
and the TPL circuitry. The TPL also provides TruPower™ Limiting voice coil
protection.
The control board module is unique to each product in the Self-Powered Concert
Series and M Series amplifiers and these amplifiers can be re-configured by
simply changing this module with another TPL control board e.g.:
