Macbook pre cueing griffin cable

I have DJay Pro on the macbook pro, and working with the YAMAHA 400 stagepass speakers.
I cannot get it working…
I reed a lot about the iPhone and iPad. It seems they have an selection button.
Can anyone tell me what to do to get it working??? I tried everything!!

Please help?

Thanks in advance.


Hi Winni,

could you tell us how you are connecting the YAMAHA 400i stage pass PA system with your MacBook.
