The headphones are only stereo, two channel analog so they will only be able to use the analogue stereo output of your receiver regardless of whether the original material is DTS, AC3, multiple channels or analogue stereo, etc... So I am not sure what you mean exactly? You connect it to the two channel stereo out RCA jacks on the back and then set program mode for stereo. Does that make sense?
I see so kind of a virtual surround with two speakers or headphones. I will have to opt out and let another expert help you with that. Sorry.
From what I understand ll you need for Headphone:X tracks on Blu-ray discs is a standard pair of headphones connected to either the Blu-ray player (some have headphone outs) or your AV Receiver. It's pre-mixed, and requires no decoding. The Stax headphones I have looked at have XLR inputs or normal RCA inputs which the Yamaha has. See picture.
What model Stax is it?
I think Headphone X and DTS x are two different things: http://listen.dts.com/pages/headphone-x
You mean amplifier right not pre-amplifier? I only see RCA connectors on the pictures I found?
Can you send me a picture of the back of your amplifier?
Cinch connectors look like this:
I have never heard RCA connectors called cinch connectors I guess you are not in the USA, sorry... I would use the Zone 2 or Zone three RCA connectors on the back or you can use the surround front and put it in Stereo mode see picture.
To be clear your Yamaha is a Pre-amplifier but your STAX an Amplifier that's what was confusing me too... let me know how that works
A pre-amplifier means it needs an amplifier, they call it a "headphone driver" but it is an amplifier for your headphones... the input on the back are to connect it to your Yamaha "pre-amplifier" anyway I am not trying to argue with you about terminology you were right about cinch connectors we just don't use that term here. See here: "Changing Tubes in a STAX Tube Headphone Amplifier" The following description is specific to the STAX 006t II vacuum tube output driver unit but much of the procedure is similar for any of the STAX tube units (SRM-T1, SRM-T1S, SRM-T1W, SRM-006t and SRM-006tA/II)
Any of those pre-amp outputs will work for your Stax driver unit. Whatever you want to call it, let me know. If you are satisfied, please kindly provide an OK or Above Rating - so I get paid. Keep in mind you can always come back to this page at any time regarding this question. Thanks!!
BTW I contacted a suppler of the Yamaha pre-amp processor and this was his reply: "Regarding the Yamaha CX-A5100<http://www.crutchfield.com/p_022CXA5100/item.html>, we don’t list that it supports DTS Headphone:X."
As I thought it is a way of processing a track there are no pre-amps that will convert current DTS surround to HeadphoneX format from what I can see as of yet but see here: "If you own a copy of 'Ex Machina', 'The Hunger Games: Mockingjay Part 1' or the latest 'Terminator 2' Blu-ray release, you already have access to DTS Headphone:X tracks. For the rest of you, DTS and Lionsgate have provided two DTS Headphone:X clips on the 'Ex Machina' website (click HERE
I fancy myself an audiophile and unfortunately I lost most of my equipment in a fire a few years ago but I used to have a great pair of Sennheisers but nothing like the STAX I heard pair a few times in the past you are lucky. Let me know
