• High performances Stereo Coder: Stereo Separation > 65 dB and S/N ratio > 80 dB.
• Balanced audio inputs with high level of Common Mode Rejection Ratio (CMRR > 70 dB, from
20 Hz to 15 kHz), filtered from the RF interference and protected against Fast Transient Events
• Ground subdivision system (Audio and Chassis) optimized to avoid Ground-Loops phenomena
• Two buffered MPX outputs, each with indipendent level, allow to keep an optimum Stereo
Separation with loads as low as 50 Ohm.
• SDC2000 can deal can deal with digital AES/EBU coded input, or even with standard analog
“Left” e “Right” signals, that are converted into digital format (A/D)
• SDC2000 generates the stereo composite “MPX” directly in digital form, using as input the
digital Left and Right inputs; this guarantees:
– Maximum S/N and fidelity in the stereo signal
– Maximum stereo separation in the whole frequency range
• The SDC2000 supports a professional MPX limiter fully compliant with the ITU
Recommendation 412. This allows a continuous control of the modulation and safeguard of the
transmitting specifications (maximum frequency deviation +/-75 kHz and maximum MPX power
modulation 0 dBr).
.. The SDC2000\SFN handles all the functions needed to work in real SFN configurations
synchro of RF carrier delay time as delay line on all the inputs (Left, Right, MPX and
AES/EBU), beyond functions of the SDC2000.
• The SDC2000\GPS allows 1ppm of carrier synchronization by the built-in GPS source, beyond
functions of the SDC2000\SFN.
