2 FM EXCITER GENERAL DESCRIPTION

The MOZART FM exciter/transmitter is the result of the development of the MSE (Magnetic
Sound Enhancer) technology together with the improvements in the FM modulation and using
high performances PFC filters for the AC/DC conversion. This unit is ideal as stand alone unit
for low power transmissions or suitable as high performance exciter in modular transmitters.
This unit has been developed with the Green RF technology which increases the efficiency of
the amplification part reducing the dimensions and power consumption without modifying the
quality of the transmission.
The main advantages of this technology are:
- High RF efficiency
- Lower heating (lower necessity of air conditioning in the installation room)
- Higher devices safety
- Higher total reliability
- Lower AC power consumption
An user friendly interface with the combination of leds and LCD display offers a very easy
method to control the MOZART main parameters with a metering accuracy that helps the user
to install the unit and check its status even in case he doesn't have expensive test equipments.
In case of fault of the unit or antenna system, the protection system lowers automatically the
output power, in order to bring back the operating conditions to a safe area without causing a
system shut down, and it indicates on the front panel display the alarm message.
The protection system reduces or stops the output power in case of:
- V.S.W.R. too high.
- Heatsink temperature too high or cooling stop (OVER HEAT).
- Missing Enable command (in case of combination with external units like control
logic units)
