I have been looking at the Symphony I/O lately, and seeing that most configurations of it has the same number of inputs and ouputs. Persionally, I can't see a situation where I would need 32 outputs. My question is, is there a reason why it generally has the same number of inputs and outputs, are there benefits of this that I'm not seeing?.
even in a post environment, mixing in the box, you may find yourself needing more outputs than you might think at first.
are you patching in any phone patches for clients? - outputs
are you dealing with ISDN? - outputs
do you have any outboard gear you would like setting as inserts? - outputs
mixing beyond stereo (5.1 etc)? - outputs
headphones mixes? - outputs
The primary reason is for people working in music production who prefer to mix on consoles instead of "in the box."
