Sorry if this has been covered before, didn't see anything in the search.

I just install a NEX-6100.  I see in the various website descriptions that it is equipped with dual zone audio.  How do I enable this?  I've searched and read the manual and found nothing.....

I have a feeling I'm misunderstanding what is meant  by dual zone audio, please point me in the right direction.

Dual zone means you can hook up rear audio/video via RCA(video) and 3.5 to RCA(Audio) to rear monitor or headrest monitor. Then passengers can watch video and audio thru headphones, while drivers listens to audio of his choice, thereby dual zone.

That's a bummer.  I thought dual zone meant discrete audio to front/rear channels.  Oh well....
