Configurable Audio Input
Sensitivity
For each channel of 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 for an audio source, and to amplify the giving
minus input source to 0dBu, the figure below is an example when the sensitivity value is set to -
54dBu, and input source is -54dBu, after the gaining circuit of audio card, you'll get the 0dBu of
output.
Maximum level = 14 dBu
Input Impedance = 10k Ohm
