Searching & Reading

At this moment Iím searching about the best microphone (1) for the system. I have two microphones dynamic and electret, the problem of the electret itís about the power.

The preamplifier (2) itís important because at the output of the microphone we have only a few mV. I think to do some tests with a mixer.

The ADC is a black box from PICO, Iím reading the manual and other informationís about these converter. Is a small male plug that we insert in the parallel port and have one gate.
