Hello World
this is my first post ever, and like many others i dont know excally where it should be.
So i bought a used Behringer mixer off ebay, you can stop laughing now.
it powers up just fine, and is usable, out of the left channel.
I've been searching the net for days now, trying to figure out how to trouble shoot it, but the information is elusive, partially because mixers are driffent and partially because alot of people despise Behringer.
So, when i plug the mic in, the right slider, db meter and output's dont work.
but! if i plug head phones in, they work fine in both channels, but not the slider or db meter. and if i push the solo button in, the decible meter works but not the slider. also if i plug a crapy tape deck into the tape in, the decible meter works fine.
I open it up, discouraged i quickly closed it, then i open it up again. this time i poked around, everything looks connected, everything is sodered to the board. i did not electrocute myself when i pluged it in while it was opened.
now i cant be sure about this, cause things were upside down, but i beleave that for a moment the right channel worked and not the left, i think this happened twice, maybe right after i put the power to it. so maybe a capacitor has failed, and takes amoment to charge to full failure? i dont know. Behringer does not allow us scamatics <sp> not that it would help me much, I own a 9volt multimeter.
So im not sure if this is the site for this, if it aint could someone point me in the right direction please.
I would like to fix this myself, with your help of course, so i can learn, i got some old stereo amps and guitar amps laying around,broken, that i could rob parts off of.
any ideas? how can i test it, i'll take it to a local repair man if i have to but i dont want to.
thanks for you time, world.
peace
Tremaine
