I must have inadvertently hit a switch, as I have no metering either through the Master Section or any of the other meters.
As I understand it, metering follows the Mastering Section, unless it is bypassed. Whether the Mastering Section is bypassed or not, I get no signal to the other meters. With Mastering Section on and nothing loaded, I get no metering through it. I still get audio, so it must be passing through.
Where is that confounded switch??
