Hadn't thought of that. I will definitely test that out, however for the final build it needs to fit in the size of a backpack.

Re: Inverter Interference

the radio shack transformer is an output transformer / step down to drive speakers. note the 1000 ohm primary and 8 ohm secondary. you can try this for isolation but the volume level/signal strength will be reduced. You might try connecting the speaker side of the transformer to a speaker, then the...

Re: Inverter Interference

remember also that the el wire is a wire antenna broadcasting the RF hash out of the little inverter. If it is coming through the power circuit, test this by using a second battery. If it is through the audio side a small audio isolation transformer may fix it...Radio Shack, or rent a good one from...

Re: Inverter Interference

The transformer for the EL wire is creating 'noise' that runs through the power cable and bleeds over to the amplifier. The amp, in turn, amplifies all the signal it gets, including the noise coming from the transformer. You'll be hard pressed to make it go away entirely without a seperate power so...

Re: Inverter Interference

I've drawn up a quick diagram. I apologize ahead of time about the size... Battery is a 12V DC, 12 amp hour battery.

Re: Inverter Interference

Thanks for the posts guys! I have tried wrapping it in aluminum foil to no avail. I have some older lead lined camera cases (lead is unexposed) that I may give a shot at. When you say separate the lighting circuit, what exactly do you mean? Right now my project is setup so that audio gets split half...

Inverter Interference

I have an DC - AC inverter for EL wire. I know that they release a certain amount of an audio frequency that we can hear. My inverter is setup next to a speaker and amp, and the amp is picking up the frequency emitted and amplifying it. Is there any straight forward way to dampen the signal? Or if i...

Re: El Wire Attached To Speakers

Thanks for all of the replies! I was researching more, and found this: http://www.instructables.com/id/LEVEL-HEADED-EL-WIRE-HEADPHONES/?ALLSTEPS the general idea of what is going on in that project seems to be what the consensus here is saying. Instead of using a sequential inverter (type used in th...

El Wire Attached To Speakers

I'm building a speaker setup that will have el wire attached to the speakers flashing on and off with the music. The speakers are decent sized, but since they are relatively old, there are no specifications on them and I can't find anything online. http://www.soundtube.com/Data/Techsheets/SA202-tech...
