2. If I place the HDMI audio extractor on zone 2, would I be able to extract two channel analog audio without changing the zone 1 audio setting in the AVR? Zone two audio amplifier will be used for 7.2 configuration. Since I am not planning to have zone 2 TV, I am hoping that it will allow me to control this volume using Denon remote. True?
Any other idea to drive a separate amplifier for another area from 3500h without using zone 2 output?
What exactly is the use case you want this for? Do you want the audio as analog, digital, stereo, multi-channel, to headphone transmitters, etc?
(Also, do not buy the one you linked. See reasons below)
The typical use of an audio extractor is to "tap" the HDMI path for the audio portion to do one of
(1) feed analog stereo out to headphones or headphones transmitter if the receiver does not offer another way of doing this
(2) To feed the audio as a digital/analog signal to active speakers or another integrated amp to provide the same
sound as what is going through the original HDMI.
As such, if the audio extractor is correctly designed the original source and sink have no idea of the "tap" in the path. To be able to do this completely transparently, you need an audio extractor that can pass through the full [email protected]
hz formats, have at least 18GB bandwidth and should be speaking the same HDMI 2.x and HDCP 2.x versions as the receiver/tv. They also pass through the EDID from the TV back to receiver and allow ARC so that the HDMI path is truly transparent as far as receiver and TV are concerned.
Monoprice (amongst others) sell such units around the $40-$50 price range. Look up the reviews to make sure they don't have any quirks that may not work for your use case.
Typically these provide a stereo analog and a TOSLINK optical jacks for audio out. They can take multiple channel sound in the original path and send it out as multi-channel PCM SPDIF. But because of the limitations of the latter, it can only do up to 5.1. There are other units which also provide a second HDMI extraction but downgraded to 1.4 (1080p and 5.1 audio max) if you want both audio and video. The latter does not affect/downgrade the original path allowing content with DRM to be played through the original path.
What you want to do with that audio is entirely up to you. The receiver and TV have no awareness of this extractor and behave as if it did not exist which means no control whatsoever from the receiver or the TV on the extracted audio - no volume control, etc. So, to answer your specific question, a correctly chosen audio extractor will not affect anything in the receiver or the TV or the original viewing and has nothing to do with any zones.
You can also attach it to Zone 2 HDMI (you should avoid attaching them to the second monitor HDMI for various reasons). But this can affect the Zone 1 viewing as has been discussed earlier if using the same source for both. If using a different source for Zone 2 then you don't really need the audio extractor. So, attaching the extractor to Zone 2 really does not buy you anything.
