Thanks for the reply Ian. I would just like to clarify a point I may not have been to clear on. (and this may not be much of a clarification either
)
I used to use S1 passthrough as everyone recommended that for the digital sound connection to the yamaha amp when the FTA source was AC3/5.1. I thought this had something to do with being decoded and recoded in the S1 and ability to adjust S1 volume if you set audio to 5.1 instead.
I am assuming (possibly wrongly) that because I only have a digital connection to my amplifier for audio, that the two analog stereo channels from the LiDiC get converted to a digital stream in the S1 and out of my single digital connection to the amplifier. (as a stereo digital stream - I was not expecting synthesis of 5.1DD etc).
So it looks like if you have a LidiC you cannot use passthrough setting on the S1 for the FTA Digital audio as you need to set the S1 to 5.1 (not passthrough) to generate a digital stereo stream to the amp from the LiDiC analog stereo sources. Passthrough setting doesn't generate the digital stream to the amp for LiDiC sources, there is no sound.
If there were obvious benefits to using passthrough setting on FTA sources compared to 5.1 setting then you would need to keep going into the S1 setup and swapping passthrough/5.1 depending on if you watched FTA DD or a LiDiC source. That would be frustrating.
In the meantime I have left my S1 set to 5.1 as I get sound from FTA and LiDiC and the amplifier seems happy either way. I'll need to look closer at the amp display when watching a FTA AC3/DD 5.1 content sometime and make sure it is playing multichannel since I thought the passthrough recommendation was based on better chance of the amp recognizing the digital stream as multichannel.
regards,
Phil
