DB Broadcast - Mozart 50

Mozart-50, variable 0~50W exciter /amplifier for FM Radio Broadcast.

The DB Broadcast Mozart range of FM transmitters and exciters (ranging from 50W through to 3.5KW) are the latest line in the DB Broadcast range of FM exciters and amplifiers. Utilising the latest MSE (Magnetic Sound Enhancer) technology along with improvement in FM Modulation the Mozart range provides a higher efficiency solution without compromising on RF and sound quality.

The compact Mozart series (up to 1KW in a 2RU chassis) provides all key parameter setup and monitoring from the front panel LCD display, an optional web-interface can be fitted to provide remote IP based management of the Mozart series.

The Mozart Series includes as standard: Stereo Input with L+R audio input option for mono operation and Built-in Stereo Coder board. WEB/SNMP version 2C. Includes complete monitoring of all parameters and remote software upgrade via the WEB. I/O board for complete telesignal, telecontrol and telemeausures interface. Opto-isolated inputs and dry output contacts.


  • Hot-plug fans: 5 minutes of maintenance time, no need to open or switch the unit.
  • All the main working parameters are displayed by leds to indicate the transmitter status at first glance.
  • Latest generation LD-MOS devices increase DC to RF efficiency up to 85%, with a drastic reduction of energy consumption.


  • FM transmitter MSE™: Magnetic Sound Enhancer is a magnetic barrier that protects the VCO, the heart of FM modulator, and increases sound quality.

  • Stereo Generator: high performance built-in digital stereo coder provides separation typical > 65dB.

  • Signal/noise ratio >80dB assures the highest audio quality.

  • Input sensitivity and output deviation adjustable with high precision of 0,05dB through front panel or remotely by web interface.

  • FM transmitter level and phase of the pilot tone adjustable from the front panel and Web interface.

  • AES / EBU digital stereo audio interface available as option.

  • Powerful modulation limiter keeps the maximum frequency deviation within international requirements to avoid overmodulation and adjacent channels interference. Limiter levels can be set from the front panel.

  • FM transmitter Switch-mode power supply with power factor control. Highly efficient and widely over-rated power supply modules insure low heating, low AC power consumption and superior reliability. The power factor control circuitry meets the international requirements for mains network disturbances.

  • FM transmitter High efficiency cooling system. Thanks to the air cooling system, the heat-sink temperature can rise only about 10°C above ambient temperature. This guarantees the proper functioning even in sites with extreme climate conditions and high temperature.
