Laurence (or others if they know)

I remember a while back you said that you had used the XLR moduel on your A1 with 2 mono mics at once, with one channel set to Auto-Gain and the other channel set to manual audio levels.
Is this is fact possible, and if so, how exactly did you do it?
- I know you can have both channels on manual, with them at different manual levels, but can you have one on auto and the other on manual ?

thanks in advance
