1. Maitinimo jungtis: 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. Analoginis išėjimas:
   • For unbalanced connections, use RCA cables to connect the "Line out RCA Left" and "Line out RCA Right" ports to your ampkeltuvai arba aktyvūs garsiakalbiai.
   • For balanced connections, use XLR cables to connect the "Line out XLR Left" and "Line out XLR Right" ports to your balanced ampkeltuvai arba aktyvūs garsiakalbiai.
3. Skaitmeniniai įėjimai: Connect your digital audio sources (e.g., PC, CD player, streamer) to the appropriate input ports:
   • USB: Prijungimui prie kompiuterio.
   • LAN: For network streaming capabilities.
   • Optinis (TOSLINK): For optical digital audio sources.
   • Koaksialinis: 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.
   • Laikrodžio įvestis: 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.

Naudojimo instrukcijos

Priekinio skydelio valdikliai

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

• Ekranas: Rodo dabartinę įvestį, sample rate, and other status information.
• Įvesties parinkiklis: Cycle through available digital inputs.
• Meniu / nustatymai: Access various settings such as filters and NOS mode.
• Garsumo valdymas: Adjust output volume (if variable output is enabled).

Tinklo srautas

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

1. Ensure the X26III is connected to your network via the LAN port.
2. Kompiuteryje, prijungtame prie to paties tinklo, atidarykite web naršyklė.
3. Įeikite //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.

Digital Filters and NOS Mode

The X26III offers various digital filters and a Non-Oversampling (NOS) mode to tailor the sound to your preference. These settings can typically be accessed via the front panel menu or remote control.

Image: The front display of the Gustard X26III showing available settings for PCM filters (Vivid, Gentle, Composite), DSD filters (47K, 50K, 60K, 70K), and NOS mode (Disable, Enable).

• PCM filtrai: 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.

Priežiūra

• Keep the device in a clean, dry, and well-ventilated area.
• Venkite tiesioginių saulės spindulių, šilumos šaltinių ir per didelės drėgmės.
• Išorę valykite minkšta, sausa šluoste. Nenaudokite skystų valiklių ar tirpiklių.
• Užtikrinkite tinkamą vėdinimą aplink įrenginį, kad išvengtumėte perkaitimo.
• Periodiškai patikrinkite kabelių jungtis, kad įsitikintumėte, jog jos yra tvirtos.

Trikčių šalinimas

Nėra garso išvesties

• Check all audio cable connections (RCA/XLR) to your ampkeltuvai arba aktyvūs garsiakalbiai.
• Verify that the correct input source is selected on the X26III.
• Užtikrinkite savo ampgarsiakalbiai įjungti ir nustatyti teisingą įvestį.
• Check the volume level on both the X26III and your ampgyvesnis.
• 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.
