I am getting an Alpine 701 processor, and I would like to use the digital output on the Z2. I know there is a little box that connects to the z2 to change to an optical out. Can you get the box by itself, and will it work?

Only an Alpine will control an Alpine processor

I want to use the digital out of the z2 to the digital in of the 701. There is a separate controller for the alpine processor

I just ordered the box from pioneer. CXC3584. Should get here soon. Should allow me to use a toslink optical cable to connect to an external processor. This will alleviate the 2 volt preout issue, and decouple the headunit electrically to reduce system noise. Ill post back when I know it works.

Did you ever get this to work?

Am am looking at the same set up... Z2>h701

any updates? Does this work?

Well... not only did the processor not work, but it has totally proprietary cabling / interfaces.

So... I hooked it up through rca's and the system sounds phenominal after weeks of tuning. The only issue really is dual volume controls. I have not been able to fix one of the volume controls because of the feedback issues with the bluetooth.
