PROFLEX modular system

Analog to digital and digital to analog converters - ADC, DAC

Video: Rec.601 and Rec.656 compliant D1 signal filters.
EDH insertion in D1 streams.
Audio: two-channel (stereopair) 24-bits convertion. AES/EBU output standard with 32kHz, 44.1kHz, 48kHz and 96kHz sampling rates. Built-in test-signal generator. Analog input overload protection by presettable attennuator. Two preset levels on audio output. Manually presettable audio delay - up to 1.3sec at 48kHz sampling rate. Automatic "audio delay follows video" under "PROFITT"s networked remote controls (requires a CPU module in a rack).

Analog to digital convertors (ADC)

Video

  • PADC-3015 analog to digital converter
    • YUV/RGB=>D1
  • PMFD-3312(NR) multistandard decoder/synchronizer/ADC
    • SDI/YUV/RGB/PAL/SECAM/YC=>SDI/YUV,PAL
    • NR - with noise reducer

Audio

  • PAAD-3102 analog to digital converter with an audio delay
    • one balanced stereo input (DB-25 connector),
    • two balanced AES outputs (DB-25, 110 Ohm),
    • two unbalanced AES outputs (BNC, 75 Ohm)
    • synchronization:
      • autonomous or
      • by video signal (BNC, 75 Ohm) or
      • by external AES, balanced/unbalanced (DB-25, 110 Ohm / BNC, 75 Ohm)
