Hi,
I just installed a reburished "C4 16 channel matrix amp" to replace my old one that the power supply went out.
From the various C4 displays, I can turn the various zone's speakers on, off, pause....
However, I am unable to turn the volume up or down from C4 app/remotes/touchscreens/keypads/etc)..... the volume seems to be fixed in each zone to the max gain volume set for each zone.
Does anyone have any ideas?
Thank you,
Eric
