DB Broadcast - Mozart-2000

Mozart-2000, variable 0~2000W exciter /amplifier for FM Radio Broadcast

The DB Broadcast Mozart range of FM transmitters and exciters (ranging from 30W through to 3KW) 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 , 3KW in 3RU 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 comes standard with inputs including MPX, SCA and RDS in, operators can choose to add additional inputs as required including stereo generator, L/R inputs, Digital AES, Telemetry and Web / IP interfaces.

Main Characteristics 

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

• AUTOMATIC CURRENT SHARING (ACS): automatic current balancing system, perfect load distribution, best power supplies operating conditions.

• Maximum redundancy: due to optimized ACS system, extremely low output power loss in case of power supply failure. In dual power supply configuration power loss in case of one power supply failure will be less than 35%.

• Instant replacement of the power supplies: easy maintenance, without off-air. The power supply plug-in modules can be safely removed from the front panel without interrupting the transmission.

• Low maintenance costs for the FM transmitter, thanks to the easy access to all components, external cooling air filters, very high MTBF (Mean Time Before Failure) for RF and power supply modules.

• Compact design and low weight to reduce transportation costs and simplify logistics.

• FM transmitter Complete WEB SERVER SNMP, GSM or SMS remote control, available as an option.

• Touchscreen display (optional): colourful touchscreen bypassable for manual control to guarantee perfect operation in any transmitter site condition. User friendly, simple and intuitive.

• High-efficiency cooling system: the air cooling system limits the heat-sink temperature rise only max 10°C above ambient temperature. This guarantees perfect functioning aven in sites with extreme climate conditions and high temperature.

• Meets or exceeds all the international standards for safety and electrical specifications.

Highlights

• FM transmitter MSE™ (Magnetic Sound Enhancer): a magnetic barrier that protects the VCO (Voltage Controlled Oscillator), the heart of FM modulator, and increases sound quality.
• Stereo Generator: high performance built-in digital stereo coder that provides separation typical > 65dB.
• FM transmitter High-frequency stability in short and long terms, assured by digital PLL (Phase Locked Loop) circuit with low frift VCTCXO.
• Frequency Agile Broadband, settable directly from the LCD front panel with 10 kHz steps without the need for tuning tools.
• Signal/noise ratio >80dB to assure the highest audio quality.
  Input sensitivity and output deviation adjustable with high precision of 0,05dB through the front panel or remotely by the 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 an 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.
• 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.
