Hi. New to Roon. I am using a late 2014 Mac mini as my core. I have it plugged directly into KEF X300A Wireless speakers with a usb to mini usb.the signal path is great, my issue is everytime I use it there is a few decibels difference between them the channels, left or right and different if I shift the ports around, some times it works. I am trying a new cable but thought I would check with the community for any other reasons this may be happening?
As long as the signal stays in the digital domain, a change in balance needs processing. That does not just happen. Surely not when both, L + R are traveling trough the same cable. Looks like the KEF is a digital active speaker, so I assume that all signal processing (inc. D/A) is handled inside them. Maybe your speakers are faulty?
Did you measure? How much is it?
Note: The perceived balance does not have to come from loudness differences alone, it can also come from a delay.
I also have a rega turntable connected and zero balance issues. I can also airplay with no issue. Only via Roon do I have the issue. Sorry I mean when I try a different USB port on the back of the mac mini. Probably a 5 decible difference but it varies sometimes more.
I don’t see how that corrosion should do the math required to change the balance between L + R channels in a digital audio stream. And Roon is all about digital audio - no D/A processing included; no analog output.
