A: On the 3.5mm HP output, use at a setting between 0dB to -3dB for lowest distortion.
Lowest distortion is at 0dB to -3dB, depending on how high the digital modulation is. At less digital modulation (typical music etc.) 0dB setting has lower THD. At 0.5 FFS it’s 0.00143% on 0dB setting. At 1.0 FFS it’s 0.0036% on -3dB setting.
