4.1 Clock Synchronization Technology

The S9c Pro features a 2nd generation PLL core, a technological breakthrough that took four years to develop. This complex algorithm enables the output of frequencies corresponding to different resolutions with ultra-low jitter. The clock source is fed to both the USB XMOS and the DAC part simultaneously, resulting in natural and vivid sound. The 10MHz external clock input provides further possibilities for sound exploration.

4.2 IIS Differential Transmission Isolation Technology & Dual DAC Chips

The S9c Pro utilizes a special onboard-IIS differential isolation transmission technology. IIS signals from USB and those converted from coaxial/AES/optical inputs are reshaped by the PLL core and transmitted via symmetrical circuit chips, minimizing interference. Furthermore, the S9c Pro employs two ES9068 DAC chips that work in clock synchronization mode, optimizing their potential for superior audio conversion.

4.3 Fully-Discrete Amplifier with Twin JFET

The S9c Pro features a fully-discrete amplifier circuit with fast transient response. It incorporates twin JFETs (junction field effect transistors) at the input stage, known for their high impedance and mellow sound. Coupled with a +15V linear power supply, the amplifier delivers up to 5W of output power, capable of driving a wide range of headphones and IEMs effectively. The customized amp оутпут волtage curve ensures optimal performance for both headphones and in-ear monitors.

  • Проверите да ли је утичница функционална тако што ћете укључити други уређај.
• Нема излаза звука:
  • Confirm the correct input source is selected on the S9c Pro's display.
  • Ensure the output mode is set to "Headphone" for headphones or "Line Out" for external ampлифиерс/звучници.
  • Проверите све аудио каблове да ли су безбедно повезани.
  • Increase the volume level on the S9c Pro and your connected audio equipment.
  • Verify that your headphones or speakers are functioning correctly.
• Изобличен или лош квалитет звука:
  • Check the quality of your audio source and cables.
  • Осигурајте сample rate displayed on the S9c Pro matches your audio source.
  • Try switching between MODE 1 and MODE 2 tuning modes to see if it improves sound.
  • Ensure the product is used at 110V voltagе. Прекомерна волtage will damage the product and affect performance.
• Даљински управљач не реагује:
  • Ensure there are no obstructions between the remote and the unit's remote control receiver.
