makkk100 Posted April 28, 2014 Share Posted April 28, 2014 hello. This morning I tried to connect my StageSource L3T on my sound card (steinberg mr816csx). I would like to change the equalization decided to connect the channel 1 of the mixer L3T. Unfortunately it after trying (unsuccessfully) to channel 1 of L3T started making noise. Like white noise. What could have happened? The service here is very far and is usually expensive. Is there something I can do to fix this? here I leave a link in the video I made showing the problem. ( ) Thank you very much. Quote Link to comment Share on other sites More sharing options...
dboomer Posted April 28, 2014 Share Posted April 28, 2014 Sound cards from computers are notorious for creating noise. This is often power related from the computer side. It appears that you are running an unbalanced cable into the L3 so you'll get no benefit from the noise reduction offered by a balanced connection. Does the noise go away if you unplug from the sound card? The fix will most likely be to insert a balancing transformer between the source and the L3.

makkk100 Posted April 28, 2014 Author Share Posted April 28, 2014 Sorry, I think I was not clear ... after I tried to connect, it seems that the channel 1 of the mixer was faulty .. he is only noise .. channel 2 is normal. and now I'm trying to connect a guitar ... not the sound card. I made a new video with the problem ... and also realized that when I do not put the whole plug have sound but with noise and when I put the whole plug just keep the noise. channel 2 works ok. the problem happens only on channel 1. see new video .... thanks a lot...

dboomer Posted April 28, 2014 Share Posted April 28, 2014 OK. I can't see the PAD settings. If they are the same on both channels then it would appear you may have a hardware issue that requires service. Quote Link to comment Share on other sites More sharing options...
