Features and specifications subject to change without notice.
• 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 allows to meet all the international requirements
for mains network disturbances.

30W ÷ 30kW
• High efficiency cooling system. The air cooling system limits the heatsink temperature rise to only 10°C above ambient temperature.
This assures the transmitter ability to properly operate even in high ambient temperature sites with hard climate conditions.
• Reduced maintenance. Easy accessibility of all parts, external serviceable cooling air filters, very high MTBF for RF and power supply
modules, are only some of the characteristics that explain the very high reduction of maintenance costs obtained.
• Meets or exceeds the international standards for safety and electrical specifications.

The MOZART Collection
The latest Audio excellence in FM
Broadcasting with the new MSE technology
The new MOZART Collection with the revolutionary MSE™, Magnetic
Sound Enhancement Tech., is now the audio excellence in the FM
Broadcasting industry. Moreover:
• GREEN RF™ technology combined with new 65:1 devices is the latest evolution of the word wide famous

patented COLD FET™.tech.
The main advantages of this technology are:
• Ultra High RF efficiency ( > 80 % typ.) software optimized for each power level.
• Lower AC power consumption
• Lower heating
• Higher devices safety
• Lowest weight and dimensions in the industry
• LOWEST 2 YEARS COSTS: transmitter price + 2 years AC power consumption costs + 3 years maintenance fees
is the lowest total amount in the market. This advantage increases years by years.
ONLY 4 rack units
for 3 kW
transmitter
• 3 YEARS OF ENERGY SAVING are enough to repay the transmitter purchase cost (for powers > 2 kW)
• STEREO GENERATOR: High performance built-in digital stereo coder with stereo separation>65dB and
signal/noise ratio >85dB assures the highest audio quality.
• Top quality sound. The generated FM signal is characterized by an excellent signal/noise ratio and by negligible
residual AM and FM. All this guarantees the best quality of the broadcast signal
• AES/EBU digital interface (optional). Standard AES/EBU digital stereo audio interface available as option.
• Deviation limiter. Limits the maximum frequency deviation to a value within the international requirements.
This is to avoid adjacent channels invasion in case of accidental over modulation
• Control of the transmission and modulation parameters from the frontal panel display.
• Frequency Agile: MOZART series instant LCD front panel frequency programmability with 10 KHz steps assures
agile frequency setting without any tuning or adjustment.
• High frequency stability. In short and long terms is assured by Digital Phase Locked Loop circuit with low drift quartz.
• Broadband. No tuning or adjustments required. The output frequency can be easily changed in all the range from
the front LCD panel without any other adjustment.
• TCP/IP Remote control WEB Server/SNMP latest version 2C for full remote control system.

• USB port. For direct pc o modem connection and remote control ready.
• Electronic protections. In case of over-voltage or transmitting frequency error (LOCK) or mismatching (VSWR)
or over-temperature (TEMP) the power output is automatically reduced to keep your station on the air. Every
alarm event is displayed on the frontal panel.
• Optional. Digital input AES/EBU.
• Modular design. The modular internal construction of the MOZART transmitters/exciters widely simplify the
maintenance with easy identification of the modules and reduced number of interconnections among them.
• Compact size and reduced weight. The series is characterized by very small dimensions and very low weight,
reducing transportation costs and simplifying the logistic.
• External reference oscillator: 10 MHz input SMA 0 dBm.
• N+1 facility (optional).N+1 facility control available to modify remotely the frequency and power output for
redundant systems.
