I wanted to find out with anyone out there... I'm finding that I'm getting feed back all the time when I use a mixer. From being at the club or at a friends place but it doesnt happen when I use my amp. Can someone help me with this issue? Thanks!

Hello
Feedback from where??
What kind of noise?
Does you mixer have a 3 prong plug (for the grounding issue)?

Same question as Andre and what he is leaning towards is electrical out-of-phase and ground loops.
Some suggestions, try using a one of the following:

1. Ground Lift plug on your mixer if the answer to Andre's question is Yes.

2. Instead of regular RCA cable from soundcard to mixer use a ground loop isolator for each channel

3. Then lastly it could be simply dirty power, try using this to plug your gear into instead of a surge bar

[This is one example, several type to choose from.]
*This is really handy for those that have external harddrives, will save you @$$ if there is a total loss
of power on those mobile gigs. Plus, most backup devices also work as power conditioners to help
clean up that dirty power.

Hope this helps,

The feed back is like a bad distortion, like the song being way too high. I thought it was because the song may be too high but its not that... its ever song. I like the idea of the RCA ground loop and i will try that. Thanks again!
