George ,
As I am hoping to rackmount my kit before Christmas , I have only ever set up the system in a very basic way ie. no MRC , all speakers to Large and sub crossover at or near 35hz if memory serves ( I'm at work at the moment will have to check settings file later ).
To be honest , I was a little awestruck when I first heard it out of the box(es) so I didn't think to tweak too much while running in .
One thing though , the fault has hardly been appearing for a number of weeks , but this week I did a fetch from processor to add one new device via HD621 . Stored back and since then nothing but trouble . I changed nothing apart from the new device .
I wanted to add one of these Component to HDMI convertors to 598 so I could continue to use it after its rackmounted :
http://www.hdcable.co.uk/component-hdmi-converter.html Does anybody know what way a 598DC outputs video btw because the Home screen appears briefly on screen then disappears and the tv shows ' mode not supported ' message so no video and no audio without video
