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 uitset voltage curve ensures optimal performance for both headphones and in-ear monitors.

5. Onderhoud

To ensure the longevity and optimal performance of your Aune S9c Pro, follow these maintenance guidelines:

• Skoonmaak: Gebruik 'n sagte, droë lap om die buitekant van die eenheid af te vee. Vermy die gebruik van vloeibare skoonmaakmiddels, aërosols of skuurmiddels, aangesien dit die afwerking of interne komponente kan beskadig.
• Ventilasie: Ensure the unit has adequate ventilation. Do not block the ventilation openings.
• Omgewing: Operate the S9c Pro in a clean, dry environment, away from direct sunlight, heat sources, and excessive dust or moisture.
• Skakel af: Skakel die eenheid altyd af en ontkoppel dit van die kragtoevoer voor skoonmaak of as dit vir 'n lang tydperk nie gebruik gaan word nie.

6. Probleemoplossing

If you encounter issues with your Aune S9c Pro, please refer to the following common troubleshooting steps:

• Geen krag:
  • Ensure the power cable is securely connected to both the unit and the 110V power outlet.
  • Check if the power switch on the rear panel is in the ON position.
  • Verifieer dat die kragaansluiting funksioneel is deur 'n ander toestel in te prop.
• Geen klankuitset nie:
  • 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 ampversterkers/sprekers.
  • Kontroleer alle oudiokabels vir veilige verbindings.
  • Increase the volume level on the S9c Pro and your connected audio equipment.
  • Verify that your headphones or speakers are functioning correctly.
• Verwronge of swak klankgehalte:
  • Check the quality of your audio source and cables.
  • Verseker die sample 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 voltage. Oormatige voltage will damage the product and affect performance.
• Afstandbeheer reageer nie:
  • Ensure there are no obstructions between the remote and the unit's remote control receiver.
  • Kontroleer en vervang die afstandbeheerbatterye indien nodig.
