Hello,
I'm trying to build a microphone that applies voice effects. It will be used for live performances on PA speakers. Right now there is an electret mic hooked up to the mic input on the Teensy 4.0 audio board. The audio output will be routed into a mixer which will then go to loudspeakers.
I need some help figuring out how to amplify the sound to be loud enough for a big system while also minimizing noise. I think I need an amplifier and a mic preamp to achieve this. Ideally both of these would be breakout boards that can be integrated into the mic unit. However, I'm getting a bit lost trying to figure out the specs for what I need. Here are my questions:
1) Am I overthinking this? Would it be perfectly fine to use the headphone jack output for this and skip the amp/preamp nonsense?
2) If #1 is a no, then how powerful does the amplifier need to be? i.e. how many watts should I be looking for?
3) Would a preamp with gain of 40-60dB help to reduce the input noise?
4) Is it appropriate to send preamp-ed mic signal to the mic input or should the signal go to the line input?
Thank you for your help.
