    Description

    Mozart series – the latest Audio excellence in FM Broadcasting

    FM transmitter – Radio transmitter :  the new Mozart FM Transmitter – Exciter Series is the latest audio excellence in the FM Broadcasting industry with revolutionary Audio & RF technology.

    MAIN CHARACTERISTICS:

    – The GREEN RF™ technology, combined with new 65:1 devices, is the latest evolution of the world-famous patented COLD-FET™ technology applied on DB’s transmitters.

    – FM transmitter Low maintenance costs thanks to the easy access to all components, external cooling air filters, very high MTBF for RF and power supply modules.
    – Compact design and low weight to reduce transportation costs and simplify logistics.
    – FM transmitter High frequency stability in short and long terms assured by Digital Phase Locked Loop circuit with low drift VCTCXO.
    – FM transmitter Complete WEB SERVER SNMP, GSM or SMS remote control, available as option.
    – FM transmitter Complete remote management via WiFi with WiFi Touch, available as option.
    – FM transmitter External reference oscillator, available as option: 10 MHz.
    – Frequency Agile Broadband, settable directly from the LCD front panel with 10 KHz steps without need for tuning tools.
    – Meets or exceeds all international standards for safety and electrical specifications.

    • 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.
    • FM transmitter High frequency stability in short and long terms assured by Digital phase locked Loop circuit with low frift VCTCXO.
    • Frequency Agile Broadband, settable directly from the LCD front panel with 10 KHz steps without need for tuning tools.
    • 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.
