Hello everyone, I am getting into the world of electronics applied to the field of music. I have built a pre-amplifier circuit for an electret microphone controlled by a PTT that closes with GND, and I am facing the following problems:
The model of the headphones is as follows: Sennheiser GSP 302.
Attached is my schematic, thank you very much.
- I have to get the microphone too close to my mouth for it to work.
- Without pressing the PTT, when I speak excessively loud with the microphone close to my mouth, it can be heard through the speakers.
- We have tested to change R99 to 1k and R96 to 100k but it doesn't work.
