"Hidden " volume control.

[gabe]

Just playing around with the XMC1 trying to figure out why since the HDMI update it will not any longer turn on the system when a disc is inserted in the Oppo. Never did get that to work again, but I did discover two hidden volume controls I did not know existed.  I am not much of a bass and treble guy, I generally leave everything flat and let the chips fall where they may. As it happens the disc I had inserted that did not turn the system on was a digital version of an older album and I thought I would bump up the bass a little. What I did not know is the bass and treble controls have no effect on tone but just decrease the overall volume at a rate of about 2:1 as you go up in tone. Who knew!

That’s interesting...
I'm running the XMC with the original board and 4.1.
With that, the bass and treble controls certainly do, in my setup, impact those frequency ranges independently.
For my speakers, the flat setting on the XMC, is a tad bright for my preference, so in the persistence settings, I have it knocked down a couple of notches.
For years, tone controls have sometimes been referred to as volume controls and indeed they are, under certain conditions.
