    Hi,

    Following the demise of my previous amp I spent the weekend trying to set up my new Marantz SR 4001 and PS3 connected via HDMI.

    All was going well with the amp with correct test tones and levels.

    But as soon as I turn on the PS3 the test tones on the amp all get reversed (left = right etc).

    The problem goes away if I output sound from the PS3 via optical to the amp and just the video via HDMI.

    Any ideas?

    Do I lose anything by using the optical out?

    Cheers

    Optical can't do the high bandwidth PCM outputs that HDMI can, so no 7.1 bluray goodness..

    You say the test tones get reversed? Surely they're generated by the amp? HDMI should have nothing to do with it - in which case I'd get in touch with the dealer and see if it's a known problem with a fix.

    Cheers,

    Yep the test tones are produced by the amp and "magically" get reversed once the PS3 is turned on . Very Odd.

    Do you mean the amp dealer?

    Also I only have a 5.1 speaker setup, do I still lose anything?

    Thanks again

    I'd contact the dealer - it may be a known fault with the HDMI on that amp and have a fix eg. firmware upgrade.

    The bandwidth of a PCM track off a bluray far exceeds a DD or DTS 5.1 track so yes you're losing quite a bit... if you only have cheap speakers then you may not notice it, but I can definately tell the difference on my £200 wharfedales - and they're decidedly low end.

    Does it work correctly with another HD source (take the Marantz into your dealer or a specialist hi-fi shop, if he is'nt, and ask to audition some HDDVD/Blueray decks)?

    Anyway is this actually true, optical can't physically transfer the lossless bit streams cos seems a bit unlikely as its a fibre optic cable and the amount of data you can get down one of those is massive. I suspect its its more to do with drm related rubbish and another way of getting people to upgrade their amp....

    More off topic I know but from wiki:-

    Optical fiber can be used as a medium for telecommunication and networking because it is flexible and can be bundled as cables. It is especially advantageous for long-distance communications, because light propagates through the fiber with little attenuation compared to electrical cables. This allows long distances to be spanned with few repeaters. Additionally, the light signals propagating in the fiber can be modulated at rates as high as 40 Gb/s [Ramachandran (2001), "Higher-order-mode dispersion compensation: enabler for long distance WDM at 40 Gb/sec", Proceedings of the SPIE 4532: 220-226], and each fiber can carry many independent channels, each by a different wavelength of light (wavelength-division-multiplex WDM). In total, a single fiber-optic cable can carry data at rates as high as 14.4 Pb/s (circa 14 million Gb/s)

    Thats a lot of data!!
