Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems DTS HD does not sound right

Hello,

I have G68ADV with HD621 connecting via digital audio out, when I watch Jurassic Park in DTS HD, I felt like the Meridian unit is not decoding right. It's like I don't get the surround sound. I have configured my Bluray player to output PCM and not down mix.

Is my Meridian G68ADV unable decode DTS HD?

Thanks.

With the scenario you describe, it is the Blu-ray player doing the decoding - suggest you check the Blu-ray settings once more, there may be other settings concerning secondary audio that may be interfering etc, you need to look beyond just the PCM setting.

If you are sending multichannel PCM correctly into the HD621 - the fact that it is DTS HD is no longer relevant as far as Meridian is concerned.

As above, double check the blu-ray player settings if other formats work OK through the HD621.

The HD621 will strip the PCM sound and pass it to the G68. It requires your player to convert the DTS HD to PCM.

Vanilla Dts will be decoded by the G68, but the HD versions are not.

Pretty sure you need to tweak your player to do this.

And when you say that you are connecting via digital audio out - I assume that you have all three digital cables connected? You only get two PCM channels per coax cable from the HD621.

JCD,
I have connected 3 coax digital out from HD621 to G68ADV, and HDMI from Samsung Bluray player to HD621.
Thanks.

Do a channel test from the BD player for all speaker positions.
Can your BD player decode DTS-HD to PCM 6/8 channels and send it over HDMI?

Which BD player model is it?

Hello Crion,

My Samsung Bluray model number is BD-D5500.
How Do I test from the BD playere for all speaker positions in DTS-HD?

Thanks.

Hi,

On another thread VK suggested checking the 2+2+2 settings on the G68.

BD setup discs or movies with the THX optimizer tool like T2 Skynet edition for example.

Hello,
My HD621 Property audio output: Smartlink, Linear PCM: 8ch.
When I set my BD player to output PCM, and I play DVD Essentials there is no surround channel being play. When I set BD player to Bitstream Uncompress there is surround channel being play.
Thanks.

Try setting the HD621 to 6-channel and 'un-tick' the support for 'DTS 5.1 Ch' and 'Dolby Digital 5.1 Ch' within the HD621.

The idea being to force 100% PCM from your BD player for all source types. Currently it would seem that you are only getting the lossy core out of the BD player rather than the full HD soundtrack.

As per my earlier post, also make sure that you have disabled secondary audio within the BD player.

If none of the above work, see if you can try using a different BD player. There are subtle differences between players and the settings they allow, certainly in the past certain players had issues with some of their firmware releases - also check that you are using the latest (good) BD player firmware.

Have you checked that the Bluray source is correctly set to the MD1 input (or MD2 whichever you are using) in the source properties of the G68?
