Hello -

I have a CIX 670 set up with 4 zones on a BIOU. Not that I think this makes a difference in the grand scheme of things, but the configuration is as follows:

Zone 1 - 3 speakers
Zone 2 - 2 speakers
Zone 3 - 5 speakers
Zone 4 - All call to all speakers (no phones)

Zones 1- 3 work fine , but when I conenct the brown/white for zone 4 it has now created a common connection and whenever zones 1-3 are activated all the speakers are conencted instead of just the ones in their zone. As soon as I take out the brown/white then zones 1-3 work fine but zone 4 doesn't work at all. The wiring is like the diagram provided in the I&M manual.

What I need is for Zone 4 to activate all the extenal speakers (no phones), but have zones 1-3 work seperately.

Hopefully this made sense! Please let me know what I am missing. We have talked to tech support on 4 seperate occassions, but we are still missing something to get zone 4 to work correctly.

Thanks for any help! :bang:
