Using a notebook computer, a mackie 1202 and an Maudio Firewire 410 interface: I'm getting some sort of RF noise. Sounds like I'm picking up a wireless network, cell phone or wireless phone. If I unplug the power cable on the notebook, it reduces the noise by 50%. Turns out I'm getting 2 different types of noise. One steady one and then an intermittant one which seems like it's RF noise. I'll try the ground lift on the notebook computer and I assume that'll fixe the steady noise since the noise partially abates when I unplug the notebook but the other noise seems to be generated by the cables going from the line outs of the maudio and into the input of my mackie 1202. If I disconnect the maudio, the mackie is dead quiet. On the other hand, if I disconnect the mackie and run the maudio direct to my monitors (and with the laptop unplugged) it's also dead quiet. Sounds like the cables are introducing the noise. I've tried several different cables but it does the same thing. The mackie has balanced 1/4" jacks going in but unfortunately the maudio has unbalanced line outs. Any other thoughts?
