Lowpass filter mode
There are 7 different filters (internal configuration of the ES9038Q2M)
built in the M11S for your preference.
Filters are the sound effects born with the chip, which only has slight
adjustments for the sound. Here are some introductions to different
filters. These are only for reference since actual listening also has
something to do with the matched device.
1) fast roll-off,linear phase filter: Most Common filter with clean
suppression and high rejection, best for music with high transients.
Provides crisp clean highs
2) slow roll-off,linear phase filter: coherent and clear sounds, positioned
near the middle. It is suitable for classical music.
3) fast roll-off, minimum phase filter: Minimal Pre- Ringing, preferred for
Imaging and soundstage. No aliasing in frequency domain. Stronger
bass than Linear Phase,clean highs
