1. Napajalni priključek: 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. Analogni izhod:
   • For unbalanced connections, use RCA cables to connect the "Line out RCA Left" and "Line out RCA Right" ports to your amplifier ali aktivni zvočniki.
   • For balanced connections, use XLR cables to connect the "Line out XLR Left" and "Line out XLR Right" ports to your balanced amplifier ali aktivni zvočniki.
3. Digitalni vhodi: Connect your digital audio sources (e.g., PC, CD player, streamer) to the appropriate input ports:
   • USB: Za povezavo z računalnikom.
   • LAN: For network streaming capabilities.
   • Optični (TOSLINK): For optical digital audio sources.
   • koaksialni: 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.
   • Vnos ure: 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.

Navodila za uporabo

Nadzor sprednje plošče

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

• Zaslon: Prikazuje trenutni vhod, sample rate, and other status information.
• Izbirnik vhoda: Cycle through available digital inputs.
• Meni/Nastavitve: Access various settings such as filters and NOS mode.
• Nadzor glasnosti: Adjust output volume (if variable output is enabled).

Omrežno pretakanje

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

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 brskalnik.
3. Vnesite //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 filtri: 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.

Vzdrževanje

• Keep the device in a clean, dry, and well-ventilated area.
• Avoid direct sunlight, heat sources, and excessive humidity.
• Zunanjost očistite z mehko, suho krpo. Ne uporabljajte tekočih čistil ali topil.
• Poskrbite za ustrezno prezračevanje okoli enote, da preprečite pregrevanje.
• Občasno preverite kabelske povezave, da se prepričate, da so varne.

Odpravljanje težav

Brez izhoda zvoka

• Check all audio cable connections (RCA/XLR) to your amplifier ali aktivni zvočniki.
• Verify that the correct input source is selected on the X26III.
• Zagotovite si ampso zvočniki/ojačevalniki vklopljeni in nastavljeni na pravilen vhod.
• Check the volume level on both the X26III and your amplifier.
• 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.
• Verify that your network is functioning correctly.
• Dostop do web vmesnik (//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).

Popačen ali slab zvok

• Check the quality of your digital audio cables.
• Zagotovite 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.
