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 ఫిల్టర్లు: 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.
