Thanks for your information, becoming soon an Onkyoer myself.
You may have seen this by now, but from page 84 of the manual it says:
"12V Trigger Out
When Zone 2/3 is turned on, the output from the 12V
TRIGGER OUT jack goes high (+12 V and max.
150 mA for Zone 2, +12 V and max. 25 mA for
Zone 3). Connecting this jack to a 12-volt trigger input
on a component in Zone 2/3 will make that
component turn on or off as the AV receiver turns on
or off the Zone 2/3."
I have a 929 on order at the moment, a refurb unit in fact (hopefully clean and spiffed up, always have had very good luck with factory refurbs at discount looking/acting same as new) to replace an older very sweet sounding Harman Kardon AVR 7200 (powering sound from an old and HUGE Sony XBR 61" RPTV, the last non-flat panel in the house) that I will definitely be keeping until it dies somewhere, perhaps in my bedroom powering my KEFs there. The Onkyo will be in my family room, in wall glass fronted cabinet, running an already established 9.0 surround system there now, that will be becoming a 9.1 with the addition of some major TV wall/cabinetry work, a new sub in new cabinetry below the new television wall I need built, and perhaps some new mains/CC to also replace, thinking perhaps of some Legacys at the moment, although in my space I need a shallower depth for the mains than I have had before there, so also looking at Golden Ear, Def Tech, some others. The 929 will also be sending a trigger to my Integra in-cabinet amp, powering numerous switched and local room volumed, in-wall whole house and outdoor speakers, so a trigger was important to me.
All of this will be flanking some other stuff, Apple TV, probably a new Oppo, an LG BD, a Sony 4K 65" 900A (or 900B if I decide to wait a few months on the display, or a 70" something else w/o side speakers), my old ROKU Soundbridge large that my family loves still (at least for a bit), even a new DVD/VCR combo unit with HDMI, and who knows what just yet, shopping new AV gear is fun.
From what I can tell, the Onkyo 929 provides some serious forward AVR bang-for-the-buck at the moment compared to other units priced much higher, that I have decided I do not need to be happy in 2014 at least. The extra $, like $500 to $4,000 of them depending on how I look at it, will be better spent on the TV, speakers, finish carpentery, and who knows what else as my project soon begins in earnest.
The 929 was up against : Yamaha 2030/3030, Denon AVRs, Elite SC79, Marantz 7008 and even a Sony DA5800ES, some others unnamed also and much pricier, including separates, but the 929s features, specs, and Onkyos' experience with failed older units and need to not repeat that again, won out. If it is less than satisfying in my spaces, I have less than $900 invested with a 5 year extended warranty and free shipping, but from all the reports here and elsewhere, the 929 is very connected, capable and modern, and it is sounding like a winner. And, I think it looks very nice, too, door up or down.
I will be here from time to time, thanks all for the help as usual on the great AVS Forum resource.
I just returned a HK3700 after a disappointing experience with it.
I upgraded to a 929 and I have only been impressed with it so far.
