All To DSD
When the All To DSD function is turned on, the PCM signals will be converted
to DSD for output with sound quality further improved.
[Principle]All To DSD is mainly about switching digital signals from PCM to
DSD format. So when making digital-to-analog conversion, it can use DSD
format, enriching music styles with clearer and natural sound quality. In
addition, since the lowest format of the DSD is DSD64, i.e. 4 times of the
44.1k/16bit (just looking at the data size), the All To DSD function is
upsampling the 44.1k/16bit audio signals. Third-party apps also support All To
DSD.
[Notes] When the All To DSD function is turned on, the CPU will consume more
power, which will shorten the play time of the M15S with obvious heating on
the body.
During the process of using, if you notice that the total battery life is much
shorter than that written on the specification table on our website, please
check if the All To DSD function is turning on. It is suggested to turn off the All
To DSD function and follow the provided test conditions to check the battery
life of the M15S again.
Adjustable volume at LO
When it is turned on, the volume will be adjustable in LO mode. If it is turned off,
the volume will be fixed as maximum.
Second harmonic regulation
The Second Harmonic regulation could imitate the special distortion in Tube
Headphone Amplifier and add the Second Harmonic manually. Just like the
harmony in music. This option will work when the volume level is high enough.
So it is recommended to enable this option when you are using the over-ear
headphone with a volume level higher than 70 in the player, you will hear the
difference.
