Hi all, below is the basic way I have wired up a headset comms system (CIRCUIT 1). It works but the volume is too low and have to yell into the mike, but when the mic is pressed firmly against my lips and I talk softly it’s a fair bit louder.
After doing some digging around I found allot of examples had a 1uF capacitor and a 10KΩ resistor (CIRCUIT 2).
I’m an auto electrician and this is outside my electronics education,
1) I don’t understand the use/ reason of the capacitor nor what type of capacitor is best used in this scenario
2) I don’t understand why the MIC - goes to ground and also to the PA AMP (CIRCUIT 2)
If anyone is able to help educate me I would really appreciate it, I have looked at doing courses in electronics or audio electronics to expand my knowledge but the number of different types of courses and subjects becomes daunting and overwhelming (yes I’m on the spectrum).
