Thanks Phil. In hindsight, I probably could of used the line outs, sent them into the 664 on channel 7 & 8, and had full fader level control from the 442 . I was stuck in the thought loop that in order to send the 442 line out into the 664, I would have to do it through a regular input, and loose that mic input (I was running 10 mics) I didn't think of switching the machine to 12 input mode, because I don't own a CL6. However It would of worked with the 442.
At the end of all of this, It just would have been more convenient if the mix bus cable link worked properly.
