46 - Mic Amp & Compressor
Nick M0NTV builds, tests and fault-finds a mic amp with audio compression based around an SSM2167 board. NB. This video updates the previous one about this design (https://youtu.be/wlDDr_GVnZU) with some important corrections. My second (corrected) schematic is here: https://drive.google.com/file/d/1_gcl6-TeYkWL8605Kj2sFJbPjZsV3-ji/view?usp=sharing NB. Someone correctly pointed out that the X axis of my graph that I show in this new video was not linear as the Y axis was. It doesn't change the data but it distorted the shape of the curve. So there is a corrected compression chart that you can download here: https://drive.google.com/file/d/1qzHLAtLvSDFdcHTTs5k8GZKURe_ePXZe/view?usp=sharing Thanks very much for watching. 73 Nick M0NTV
