Looks interesting .. There seemed to be an HDMI in but no reference to it in the review. I'm guessing multiple 4K sources would have to include an extra 4K switch as well.

Cheers

It could possibly be just by updating the HDMI chipset from 1.4 to 2.0 level if jitter wins have been made in the HDMI chipset designs over the years. If we are able to detect it that is a different story.

It would have been nice if they would have a linear PSU in it though since that usually keeps noise even lower and is more listenable to the ear. Since this thing actually costs 2000£ and goes into high-end setups.

If you mean 4k game, the latency will be too long, what else?
For Netflix 4k, I think you could directly connect to your HD621.

You can either buy a source with two HDMI outputs, where one output is used for audio to the HD621 or...
buy a HDFURY (Integral or Vertex) to remove all the handshaking/copy protection nonesense. That way your source will work with the HD621 and not tell you that a non-compatible device is connected.

One output goes to the TV/projector, the other into the HD621. The video connection from the HD621 to the TV/projector is not required anymore. If you need more inputs, then add an additional HDMI switch before the HDFURY. If you have a single programmable remote, this is really no different than using the regular M remote, even though you're hiding one/two additional devices in the rack.

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.

so it takes the signal and upsamples and apodises it to the processor which upsamples and apodises that and then sends it to the DSP speakers which upsample and apodise that?

so it's really old preexisting M "special sauce" from the HD621 that's now being used in its replacement. the issue is that the price-point is wildly high for this kind of tech, esp when an Oppo 203 that was mentioned is delivered to your door for under $600 and has far more tech in it.

does all the complaining make better sense now?

The upsample/apodising is only done once in the chain, and it's best done as soon as possible.
The surround controller and speakers don't do this upsampling again, although may upsample other sources fed directly into them rather than from the HD621/UHD722.

A Blu-ray player can only output the native multichannel PCM via its HDMI output, due to copyright protection HDCP.
Hence the HD621, gets at this audio signal as soon as it can from the HDMI, upsamples and apodises, and passes it on to the surround controller.
It's all about maximising the audio performance.

Without it you are limited to inferior audio streams due to Copy Protection.

UHD722 and HD621 are the same in this regard, the UHD722 is simply the current 4k capable version.

Can I just clarify that if you have two 4k display devices - I have an LG OLED TV and Optoma UHD Projector in the same room - the UHD722 will not supply 4k to both?

Thanks,

Hi Richard,

The HDMI 1.4 socket on the UHD722 does allow 4k, but not HDR which I expect both your display devices will handle,
nor HDCP2.2 which they may well both expect.

So you'll need to use the HDMI 2.0 output of the UHD722 and then split it to your two displays.

This Wyrestorm HDMI Splitter, which we sell, would do the job.

Cheers,
Rick

Hi Rick

Thanks for explaining, I assume the board used in the UHD722 is bought in and so Meridian are stuck with 1x HDMI 1.4 and 1x HDMI 2.0 outputs, not what you would ideally choose to have.

thanks for the reply Rick. i was being a smart ass re: switcher, processor and speakers having same features, so apologies.

i'll most likely end up getting this apodizing and upsamling switcher at some point anyhow, so....
