About Line level signals.
See this link for a good explanation: http://www.shure.com/americas/support/find-an-answer/mic-level-and-line-level-what-do-they-mean
This kit expects a line level input signal. This is ideal for transmitting over long distances, so a 10m cable is not a problem.
The signal should be, ideally, 3 volts peak to peak for maximum audio quality.
This includes signal from your laptop, smartphone, mp3 player or a line out source.
Do not connect a higher level signal or you could destroy the input circuit.
If your application requires connecting an external microphone to the line in signal, you must ensure that you are using a microphone pre-amp that will boost the signal to this level.
Out of the box headset microphones will perform poorly without proper signal amplification.
I have orders some MAX9814 electret mic with pre-amp units which feature auto-gain control to keep the microphone signal at the right levels. I will try them out with the mod kit and have them for sale here if they perform well.
