GMC Forum _ CHILL OUT _ About Mic Preamp

Posted by: Renan Apr 19 2013, 07:51 PM

I will copy here the mesaage which i already wrote to the community forum of line6
I have the UX1 and i bought a microphone , and when i learned that there wasn't any "phantom power" so i bought ART Tube MP Studio Mic Preamp . It still doesn't works. First , when i connect the adapter to the preamp, the lights were on but after a few seconds lights went off and there was a smell of burning, then i realized that the adapter was burned. That's because i live in Turkey, and i know that i have to plug the adapter with a thing that lowers the electricity . The adapter burned but there weren't any smell coming from my preamp. After , i plugged my other 9V adapter which doesn't have any problem. The lights came back but there's still no voice. I plugged the microphone cable to the input and the output cable was plugged to my pod studio. The analog meter wasn't moving. Maybe i didn't plugged everything well? I even tried on the guitar but the result was same. There's a little button which has to be turn green when it works, but there's no light there.
Here , i took some photos to show you if it's correct or not:

this is the input ,

which goes to the microphone :


and this is the output ,

which goes to the pod studio:



are there any problems? might some of the electrical circuits inside of the preamp was burned? help me please

Hmmm, mate, there might be a possibility for it to be burned - I am not sure though. You should also contact the Line 6 distributor, where you have purchased the item - was it in a physical shop or, over the internet?

If you bought it in a physical shop, why not talk to the guys there? They usually have a repair shop and take care of items, if they are authorized by the producer.

You need to select an input you wish to use for ux1 in gearbox or podfarm software. It will offer you selection of "Mic", "Line", "Instrument". That might be causing the meters not to move and not being able to hear the sound from the mic. Hope its something simple as this smile.gif

Also to add a bit more help in aiding you. What microphone is it? Because not all of them require phantom power, I used a Sure SM57 and a Sennhiser e609 before and neither of them required to use it. I believe that is used for condenser microphones.

I think that what Cosmin says could be right but before that you should try the selection that Bogdan suggested, because I would affirm that something is burned if the lights are working.

I have the same setup with the UX1 and a mic / guitar. you definitely need a mic with phantom power and it looks like you have that part setup correctly.
you should have the light on the top displaying as green as this indicates it is correctly connected to the PC. If you have a red light or no light then there is an issue. No light at all sounds like its not connected to the PC or there is a problem with the UX1.
