DB Mozart 500 – 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.
- 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 over-modulation 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.
