1. Strømtilslutning: Connect the provided power cable to the AC input on the rear panel. Ensure the voltage switch (115V/230V) is set correctly for your region before connecting to a power outlet.
2. Analog output:
   • For unbalanced connections, use RCA cables to connect the "Line out RCA Left" and "Line out RCA Right" ports to your amplifier eller aktive højttalere.
   • For balanced connections, use XLR cables to connect the "Line out XLR Left" and "Line out XLR Right" ports to your balanced amplifier eller aktive højttalere.
3. Digitale indgange: Connect your digital audio sources (e.g., PC, CD player, streamer) to the appropriate input ports:
   • USB: Til tilslutning til en computer.
   • LAN: For network streaming capabilities.
   • Optical (TOSLINK): For optical digital audio sources.
   • Koaksial: For coaxial digital audio sources.
   • AES: For professional AES/EBU digital audio sources.
   • IIS: For high-performance IIS digital audio sources, typically from dedicated DDCs.
   • Urinput: For connecting an external high-precision clock (e.g., GCLK-02) to further enhance audio synchronization.

Once all connections are made, switch on the power using the power switch on the rear panel.

Betjeningsvejledning

Kontrol på frontpanelet

The front panel features a display and control buttons for basic operation:

• Vise: Viser aktuel indgang, sample rate, and other status information.
• Inputvælger: Cycle through available digital inputs.
• Menu/Indstillinger: Access various settings such as filters and NOS mode.
• Lydstyrkekontrol: Adjust output volume (if variable output is enabled).

Netværksstreaming

The X26III supports various network streaming protocols. To manage these, access the device's web grænseflade:

1. Ensure the X26III is connected to your network via the LAN port.
2. On a computer connected to the same network, open a web browser.
3. Indtast //x26.local in the address bar. This will open the network bridge control page.
4. From this interface, you can enable or disable various streaming protocols such as AirPlay, Roon Bridge, UPnP/DLNA, HQPlayer NAA, and Spotify.

• PCM-filtre: Select from options like VIVID, GENTLE, or COMPOSITE to adjust the sound characteristics for PCM audio.
• DSD Filters: Choose from various DSD filter frequencies (e.g., 47K, 50K, 60K, 70K).
• NOS Mode: Enable or disable Non-Oversampling mode. This mode bypasses digital filtering for a more direct sound.

Opretholdelse

• Keep the device in a clean, dry, and well-ventilated area.
• Avoid direct sunlight, heat sources, and excessive humidity.
• Rengør ydersiden med en blød, tør klud. Brug ikke flydende rengøringsmidler eller opløsningsmidler.
• Sørg for korrekt ventilation omkring enheden for at forhindre overophedning.
• Kontrollér kabelforbindelserne regelmæssigt for at sikre, at de er sikre.

Fejlfinding

Ingen lydudgang

• Check all audio cable connections (RCA/XLR) to your amplifier eller aktive højttalere.
• Verify that the correct input source is selected on the X26III.
• Sørg for din ampat højttalerne er tændt og indstillet til den korrekte indgang.
• Check the volume level on both the X26III and your amplivligere.
• Confirm that the power cable is securely connected and the unit is powered on.

Network Streaming Issues

• Ensure the LAN cable is securely connected to both the X26III and your network router/switch.
• Bekræft, at dit netværk fungerer korrekt.
• Få adgang til web grænseflade (//x26.local) and confirm that the desired streaming protocol (e.g., Roon Bridge, UPnP) is enabled.
• Restart the X26III and your network equipment (router, switch).

Forvrænget eller dårlig lydkvalitet

• Check the quality of your digital audio cables.
• Sørg for sample rate and bit depth of your source material are compatible with the X26III's capabilities.
• Experiment with different digital filter settings or NOS mode to see if it improves the sound.
• If using an external clock, ensure it is properly connected and synchronized.
