Waveform graphs and Descriptions

• Green: PCM 44.1/48/88.2/96(kHz), anodizing fast roll-off (Default Filter). Vocals are slightly forward, and high frequencies are extended with reduced resonance
• Red: PCM 352.8/384(kHz), linear phase fast roll-off. Enhanced analytical capabilities, delivering a clean and crisp sound
• Blue: PCM 176.4/192(kHz), linear phase slow roll-off. Enriched harmonics, full low frequencies, and natural reverb
• Yellow: DSD 64/128, minimum phase fast roll-off. Balanced and moderate sound
• Purple: DSD 256/512, minimum phase slow roll-off. Clean sound with a forward position
• White: PCM 705.6/768(kHz), hybrid fast roll-off. Soft and smooth sound with enhanced detail

Precautions

• Ensure that the Type-C header logo is facing upwards when inserting the player.
• You can download the new firmware on the official website for independent volume control.
• If the sound is too loud, please replace the headphones with higher impedance.
