Hi all,
Thanks for your suggestions.
I have set 2+2+2 to "off" in the 568 and swithched the surround connection on the HD621 from 7/8 to 5/6-but still no surround or LFE. Incidentally, I originally ran the surround cable from 7/8 on the HD621 because that matches the labelling on the 568, where sides/sub are 5/6 and rears are 7/8-I assumed Meridian would have been consistent in that regard.
As the 568 is displaying MHR Mov 96K I assume all is well with the HD621 and I don't need to tinker with that in Mconfig? Equally, the BD player is set to output PCM so no changes seem to be needed there.
Is this now looking like a 568 fault?
It still could be a player setting. Sorry I did not catch that you lost both LFE and Surrounds. That's a hint that it could still be player settings.
There are 3 modes a player can be in. Lossy 5.1, 6 Channels of PCM or 2 Channels of PCM. You might have the player set to 2 channels of PCM.
If the player is set to 2 Channels of PCM you should get good Dialog and Strong bass on your only two speakers. If you do, then it's probably a player settings.
If you hear weak vocals then it probably a problem after the player.
There are often a couple places that need to be set correctly in the player.
