Connection issue

Has anyone got issues with Soundcraft Notepad FX8 with channels 3 to 8 not being able to send them to your Mac on Adobe Audition?

The Soundcraft Notepad series is not a multitrack mixer so you only get one stereo mix output to your computer. This combines all the channels on your desk together into the computer.

Thanks Mike I’m still getting my head round it but getting there, I have found a work round by plugging my Tascam DR40X into the master out then I can use all the inputs.
