Roel,

I see your point.

I don't think that only machines with balanced outputs are professional!
I'm just saying and repeating that if SD1 is a professional equipment as really is maybe it should have balanced outputs (Afterall it's more reliable don't you think?).

About the minimum requirements for a professional equipment... I don't have a list but SD1 is a professional equipment as you want to hear!
That's why I bought even knowing about the unbalanced outputs.

Today is your first day with one more year old how is it going?

By the way, do you have the AJ's manual about the SD1? do you know how can I get it?
