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.
