When I record to to Audacity or Sony Acid Pro I get a little fuzz or static. Its not the best quality. Im thinking its my plugs.

Can anyone out there give some advice?

Yeah, that's where an interface comes in; good connections + good leads = pristine sound!

However, you are probably not going to go out right this instant and spend a couple hundred dollars on all that!

Don't despair though: try this..

Turn the output on the 606 up all the way.

Turn the input on the comp up all the way too.

Now, check your levels: they should be clipping..

Then, back off on the input level until it JUST stops clipping.

Now you will have more 'signal' to less 'noise': this is called the 'signal to noise ratio'.

If you still are not happy, try doing all of the above through the headphone out; it will be louder than the stereo outs!

Good luck man
