Do you still have your Avalon U5 Owen? I don't suppose you know the output voltage?

I'm afraid that the U5 went in the great preamp cull of 2013 It was a lovely piece of kit, but I have no idea what it put out. Sorry.
Their website says
[b]Maximum Output Level (Class A):[/b] +30dBu DC coupled, balanced 600 ohms (mic and line out)
but I am blissfully unaware of what that means
