: AC line filter question
Gary,
I'm using a new Allen -Heath Zed 10Fx mixing board with usb interface and
my cableing is brand new as well. My Win 7 I3, 8gb computer is also brand
new and I'm using Audacity 2.0.3. In a way I'm glad you don't think that
it is line noise interference
John,
Here are a couple of thoughts on this, although Gary may have some better ideas.
First, have you been able to establish whether you hear the high-pitched sound
when recordings are being monitored? I have seen
it happen where sounds like this are introduced particularly when playing back

Hi Steve,
Thanks so much for the ideas you list here. You have given me a lot to
look at. I'm going to go down through the list and start looking for
the culprit. I'll let you guys know what I come up with.
Thanks verry much!

That doesn't sound like an AC line problem. If you had an AC line problem
you would hear a 60 or 120 HZ hum. it wouldn't be high pitched.
It may be noisy circuitry in your mixer, coupled with a cabling problem,
such as poor shielding or an impedance mismatch.
