can i select more than one knob in the same time? (4example: switch between 5.1 and stereo signal)
Asked by: Anonymous
From my experience you can not select but one input at a time. The product is outstanding, though. I am in to very high end audio and have high end audio components connected like Mark Levinson, Theta, Magnum Dynalab and notice no signal degrade.
