mike,

on my Meridian legacy configuration, it has an icon that adds a product. the drop downn list contains dsp420, dsp33, 861 surround controller, 800 DVD/CD,
568 surround processor, 562 multimedia controller, and 561 surrond controller.

there is no option for the 598. Am I looking in the right place?

in the meantime I have all my channels and the 568mm is outputting pcm mus6 48K

please advise

Samuel
