Hi Ted,
That’s great – I’ve been reading up on the M&S and I get it now. I haven’t seen the back of the unti properly yet so I’ll probably understand once I see it.
What about the Phantom Power when switching between the impedence variables ? When using a non phantom mic, Is it possible to send Phantom out the output when switching past a value that applies the phantom – or should I switch the unit off if I have to sweep past a phantom enabled setting before I get to a non phantom one ?
Phantom makes me nervous – that’s all 
Thanks again,
Al.
