  • Page 15: Theory Of Operation

    Conventional CD Player with an External Digital Processor Using ClockLink with an external processor, the Wadia S7i Integrated CD Player / Decoding Computer ignores the incoming clock and uses the master oscillator at the DAC. As a result, jitter added by the external digital processor does not affect sonic performance.
  • Page 16 Note: Using ClockLink with a source other than the internal transport will result in unpredictable, degraded performance. ClockLink should only be used when using an external processor which is being fed by the Wadia S7i Integrated CD Player / Decoding Computer internal transport. For all other applications, inputs should be configured with ClockLink OFF.
