The input volume range is [-87, +86]. Both the analog gain and digital gain are adjusted.
|

A larger value indicates higher volume.
|

|
For example, the value 86 indicates the maximum volume of 86 dB,
|
||
|
|
and the value -87 indicates the minimum volume (muted status).
|
||
|
|
The volume adjustment takes effect simultaneously in the audio-left and audio-right channels.
|
||
|
|
The recommended volume range is [+10, +56].
|
||
|
|
Within this range, the noises are lowest because only the analog gain is adjusted,
|

and the voice quality can be guaranteed.
