Amplification
To control audio signal’s amplification, you can use two menu items: Gain and AGC.
First, go to the AGC:
Main Menu → Record settings →Audio settings → AGC
There are two options:
• Check box on
• Check box off
Gain parameter works in both cases:
• If AGC off, Gain sets the amplification rate.
• If AGC on, Gain limits the maximum amplification rate.
Main Menu → Record settings →Audio settings → Gain
Adjust the parameters using the slider control and then press the button to confirm
your choice.
Bitrate
To change the bitrate parameter, go to the Bitrate menu item:
Main Menu → Record settings →Audio settings → Bitrate
Depending on your need of audio signal’s quality, choose the meaning of the bitrate
from the list:
• 32 Kb/sec
• 64 Kb/sec
• 96 Kb/sec
• 128 Kb/sec
