An electret mic IS a condenser mic. Neither of which would I want anywhere near a speaker on the same amp.Hey all...
I am STILL fighting with using my J&M headset to also connect to my Android whilst the bike... At least I am determined... :ROFL:
Anyway- Iam REAL close to success... essentially, I just need to run a small electret mic in addition to the condensor mic already in the chin bar.
Everything wiorks fine... with one little problem- if I turn up the Intercom volume while using the phone, I get tremendous feedback after the dial is at about 9:30-10:00 posiiton. The person on the other end of the phone does not hear it.
For now, I have to remember to turn off the intercom if I use the phone. Not ideal, but functional...
There does not seem to be a positional problem vs the condensor mic since moving it does not alleviate anything. I do not get feedback with the Goldwing radio (I have not tried it with the CB though).
So, how do I eliminate the feedback? Diode? Resistor? Flux capacitor?
So, while I wait for this answer, I guess I will clean up my workbench (weeks of working with wiring, etc), and then install my new Stebel Compact Nautilus horn I got at Daytona bike show. Can't wait for that beep!
Condenser mics are designed to be omni-directional high sensitivity.
The problem you are having is why magnetic mics are used on bikes most of the time. Even ceramic mics can be problematically sensitive if not managed properly.
The other common problem is that since the mic and headphone speaker wires run in the same cables, crosstalk can cause oscillation easily if shielding and routing isn't addressed. This is what sounds like your problem is and possibly combined with the possible misuse of an over sensitive mic as well.
I have no way to know which from here but the short answer is... It's either acoustic feedback or induced electrical feedback or both.
You can always run the mic or headphone speaker wires down a different pair to get them away from each other for testing at least to try to see if it solves anything. It's a matter of isolation of several possible causes.
