Not control room POT noise, but just control room noise...

[indiecodemonkey]

Hello all,

It seems that I have a noisy monitor section on my Command 8. I've read the other posts here, and most people are complaining about scratch pots and whatnot, but my pots are fine, it's just the monitor section is NOISY.

The only way I can get the noise to go away is if I put the Main Monitor inputs on +4, and the Outputs section on -10. But with that combination, I lose a lot of the volume of the overall audio out. Not that it's a bad thing, it does get louder than 85 dB, but it would be nice to know what I'm hearing when I mix, is the sound I'm gonna hear when playing the cd or mp3 I'll bounce of the mix.

If I put the Main Monitor Inputs on -10, I get a slight buzzing, same thing if I put the Outputs on +4. If I do that in combination, and get TWICE the noise. What is the "standard" method for monitoring on the Command 8? Are there some combinations that are "bad"?

FYI, I'm judging this noise by turning the monitor level control to max on the Command 8 just listening, no audio is being passed through the system at this point.

And just to be sure it wasn't a ground loop, I plugged the Command 8 into a HumX power adapter from www.ebtechaudio.com. This thing BREAKS ground loop noise big time... I use it on my laptop when running SampleTank, and then running my outputs to my monitors. Without plugging the laptop in through the HumX adapter, I get tons of crappy ground loop noise. So I know the adapter works. Again, when plugging the Command 8 into it, I still get the same monitor section noise as described above.

So it's GOTTA be the pre's on the monitor section, right? And I assume these pre's are Focusrite pre's.

So, is this a known issue with Digi, the noisy monitor section (not noisy pots, my pots are 100% fine, no noise at all when turning them). If anyone else had/has this problem, can you let me know what you did to fix this?

Seeing as how I bought this unit off of eBay, I don't have a warranty, so I don't know how much $$$ it would cost to send it back to Digi for them to take a look at it.

Thanks,
Mike
