Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems Meridian UHD722 Trade-up promotion announced

Hi All,

Reading the comments a few seem to have missed the pertinent role of the HD621 and UDP722.

These aren't HDMI switches.
(Well they are, I know, but I shall explain)

They are designed as Meridian's way to get the best sound from Blu-ray.
Think of them as a box containing the 'special sauce' that Meridian would have added into a Meridian Blu-ray if they had made one.

They take the multi-channel PCM soundtrack from DTS Master and Dolby True-HD off the HDMI signal, upsample and apodise it to 96/24, and pass it on to the surround controller.
This job is done in the HD621/UHD722 as it keeps the jittery HDMI signal away from the other signals in the controller, and as soon as possible in the chain to maximise performance.

It's more by way of convenience that they have multiple HDMI inputs, but that's not their raison d'etre.
