feed back in bucket

[djloud]

ok i know there is a topic like this but what is the best way to prevent this feed back?

1. cap off and seal the back of the speakers also fill with cotton?

2.place mics in back of chest plate?

3. cover speakers with aluminum and fill with foam or cotton?

 

please help some one

thanks

you can try adding a variable resistor in line between the amplifier and microphone to reduce the gain, this may help. fine tune it until the feedback stops, but this may reduce the overall volume a bit

Where are your speakers located? If they are contained within the aerators (as in the kind Stomper used to sell here), then I'd go with the first option you listed.

 

If you have a plastic toy Easter egg or something like that laying around, you can fill each half with some sound-dampening material (cotton padding?) and use the two halves to cap off the speakers from inside the helmet, with the wires running underneath the caps to your amplifier and mic.

ya they are in the aerators but ill have to do that anyway i guess lol but ill let you guys know how it works

 

oh the amp mod saudering a red wire does not work

I´ve never experienced any feedback problem but I stuck some blu-tack around the hole and the wires on the inside just incase, so that might be a tip for you

I think I have a tutorial on here which shows how to successfully make in helmet speakers

 

The trick is to limit the backward inward sound by several means.

 

At first I tried aerosol caps and filled them with blutac. That worked great.

 

Next step was for me to get my vac former out and make these

 

Hollow out the helemt and superglue the hovi tips into the recess

----------

This way sounds prjects clearly outward

 

--------

 

Also use one of these mics

--------

 

Not one of the pad like things Bikers like to use. Feedback city with those

 

Out of interest, I have some spare speakers and left over formed caps:)
