Default Just a little noise

Ok. I finally set my system up running digital into bit one from my android phone. It's quite impressive sound wise. Noise floor is dead silent. Problem is that I notice the small amount of noise now using iPod, CD, Bluetooth and all. It buggs me and will be noticeable in SQ comp. Assuming noise is not from bit one now or amps I'm wondering what to check. I recently ran stinger 8000 series RCA to bit and using an Alpine 920hd.

I know iPods have a very high pitched noise to them.
Plugged into a Kenwood iPod interface cable it does it constantly...
I have to disconnect the iPod to remove the noise...

Having had a fiber optic digital input in a previous system, i can tell you it will spoil you the moment you go with anything else less than digital connection, which I now have.

So if only your phone is digital and the rest are RCA's, then you will notice it, especially if your into tuning and critical listening. So, perhaps what you are hearing is the reality of anything less than your quality digital input.

Will the SQ Comp rules allow you the option of using your phone as your source when the judges come around....I would think you should have a case at least to make such a request.

I asked on USACI fb page. Unless a judge has an android source it seems like I can't. I thought I could download a copy of test disc but they don't want people altering the file. It kinda sucks I can't use my best source for judging but I do kinda understand

Yeah its an inner rater reliability issue......not that their is no subjectively/bias or inconsistencies in the judging process already....but this one, at least, is one they can control.

Lol, i went from digital to high level inputs via my Bit 10......so it could be worse than your digital/RCA connection Think of the bright side
