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.
Maximum level = 14 dBu
