Emu XL-7 & MP-7 User's Group

If you're getting a hum in the main audio outs, chances are it's a ground 
loop.  Other culprit could be power cables laying on your audio cables 
(they should always cross at 90 degree angles if they must touch).  You 
can test the ground loop problem by using a "ground lift" plug adaptor 
available from pretty much any electronics stores.  IF his fixes the 
problem though, DO NOT continue to use it as a solution.  You could 
potentially cause a lot of problems with your XX_7 by leaving it 
ungrounded.  It will at least help you narrow down your trouble shooting. 
Plenty of articles online about resoving ground loops, just do a google 
search.

do anyone know how to fix this   (humm)

2) Connecting analog (main or sub):
A humming sound is added to the signal. When I close to software 
mixer of the Audiophile the humming stops, but still leaves a lot of 
noise en crackles. Totally not acceptable.

Are both problems recognized by anyone? Do the seem to be related?

I also checked the XL-7 on a simple home stereo. It also produces 
noise, but it's only noticeable on high volume.

Maik
