I've done this a few times. There is no delay on zone 1 and 2 on integra IF zone 1 is in direct or stereo. It works great! In my macros on control system, anytime the zone 2 is turned on it auto selects the correct audio for zone one. Then turns it back to dolby or whatever when zone two is turned off. Works like a champ! Downside, you lose surround sound in zone one and only get left and right speakers in zone one. Not a big deal as typically if they want sound in zone 2, its just music anyway.

If zone one is on direct or stereo, there should be NO sound in center speaker, right? Isnt that what direct and stereo is, no center channel! only left and right.
