riMac Phone/Audio Output

Hi @*,

what´t are the exact technical specs for the Headphone Out? Is it also a true LineOut Signal?

I want to connect the iMac to Mackie´s Big Knob and need to know whether the output is balanced (+4db)

or unbalanced(-10)? Stereo mini Jack? Other jacks also possible, except optical?

Thx.
