Commercial noise eliminating DSP module AGC mic PCBA + mic
The NEDSP1068PCBAMIC module is a small DSP cancellation module, designed mainly for cleaning up noisy voice communications in the microphone path.
It is based on the proven bhi NEDSP1061 pcb module but has the added feature of an on-board AGC mic preamplifier with various options.
This enables the module to be fitted easily into the microphone path of a target audio system, as well as in the receive path for use with line level audio signals.
The NEDSP1068PCBAMIC has an on-board SMD microphone and the adjustable AGC MIC preamplifier circuit.
