Addendum to testing above:
I decided to see if this huge noise difference also existed through my EV PXMs. It does and doesn’t. The QC is noisier than the QCM but I can barely hear it either way. I need to crank the EV’s volume and have my ear up near the speaker to hear the noise. So I think it’s a non factor in tha setup (through an FRFR type system) so perhaps that’s why not many people complain about noise issues.
Hm. I should probably check the difference, if any, through the amp’s FX loop. Duh.
The noise difference is still evident through the amp’s FX loop, but similarly to the EV’s I don’t think it’s an issue. I had to turn the amp’s master volume up to noon to make it obvious (ch 1 master controls it in a straight into the loop scenario). That would be super loud.
So to add to the conclusion above, if you’re running into the front of your high gain amp you just don’t want to be using the QC. Not sure about 4CM but I’d expect similar results.*
With the QCM you’d be just fine running into the front. So…
