[AudioI] octo

[Alberto Novello]

Hi Matt, the new soundcard looks awesome does it have 2 inputs and 2
outputs or more?
I also would like to ask one more question about the OCTO, what are the
output levels? I'm trying to design my amplification circuit before I
receive it.
I need two channels at -5, +5V and 3 channels at 0, 5V
Thanks so much.
