Configurable Audio Input
Sensitivity
For each channel of a configurable audio input card, there are five levels to gain the audio
signal. They are sensitivity values of 0dBu, -12dbBu, -24dBu, -40dBu and -54dBu
respectively. The meaning of sensitivity value is how large the gain is for an audio source,
and to amplify the giving minus input source to 0dBu. The figure below is an example of
when the sensitivity value is set to -54dBu, and input source is -54dBu, after the gaining
circuit of the audio card you'll get the 0dBu of output. For more information as reference,
please see this.
