Алдыңкы панелдин башкаруу элементтери

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

• Дисплей: Учурдагы киргизүүнү көрсөтөт, сample rate, and other status information.
• Киргизүү тандагыч: Cycle through available digital inputs.
• Меню/Орнотуулар: Access various settings such as filters and NOS mode.
• Үндү көзөмөлдөө: Adjust output volume (if variable output is enabled).

Network Streaming

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

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 браузер.
3. Кириңиз //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 Чыпкалары: 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.
