Rossini Clock

For å få gjengitt det aller beste innen lydgjengivelse må musikken overføres nøyaktig på riktig tidspunkt. Ustabilitet i denne timingen kalles jitter – dette finnes i alle digitale systemer. I et dCS-system kan DAC fungere som en masterklokke, men lyttetester har vist at det ikke er noen erstatning for en høykvalitets dedikert klokke. Rossini Clock tilbyr tre separate klokkeutganger – med ulike frekvenser – dette til å brukes sammen med Rossini DAC 2.0 eller The Player 2.0.

  • Type
    Class 1 Master Clock.
  • Clock Frequencies
    44.1kHz or 48kHz.
  • Colour
    Silver or Black.
  • Dimensions
    444mm/17.5” x 435mm/17.2” x 64mm/2.6”. Allow extra depth for cable connectors.
  • Weight
    8.3kg/18.3lbs.
  • Clock Accuracy
    Better than +/-1ppm when shipped, over an ambient temperature range of 10°C to 30°C. Typically +/-0.1ppm when shipped and stabilised.
  • Wordclock I/Oworldclock Inputs
    3 independently buffered outputs on 75Ω BNC connectors. Output 1: fixed at 44.1kHz Output 2: fixed at 48kHz Output 3: 44.1kHz, RS232 controllable.
  • Startup Time
    Typically 1 minute to rated accuracy.
  • Local Control
    RS232 (limited to Power and Clock 3 output frequency).
  • Power Supply
    Factory set to either 100, 115/120, 220 or 230/240V AC, 50-60Hz.
  • Power Consumption
    3 Watts typical / 4 Watts maximum.
  • Designed for maximum flexibility as output configuration can be optimised in systems with a wide variety of digital audio sources.
  • Dual crystal oscillators with microcontroller-enhanced temperature correction.
  • New dual frequency output and auto- clocking mode used in the Vivaldi and Rossini range improves ease of use and minimises jitter, particularly with computer audio sources.
  • Multi-stage regulation ensures sensitive clock and PLL circuitry is unaffected by digital interference.
  • Aerospace-grade machined aluminium chassis fitted with tuned acoustic damping panels reduces magnetic effects and vibration.
