!
The Macbook is the connected with a external USB disk as a storage
Audio are Meridian digital speakers DSP with 861 218 and Trinnov Amethyst as different zones.
See on the righ side only two outputs on the Trinnov audio zone instead of three
The Amethyst have 3 digital in and 3 digital outputs.
Play the builtin(861)ID40 meridian zone or the 218 zone is no problem.
Play the Trinnov Amethyst over the meridian/Roon network is also working-just make it clear-
the Roon Ready go over the newtork to the Amethyst as an input when the âAmethyst zoneâ is selected.
With 218 and ID40 the particul devices get the Roon streaming over their network input.
Two channel on Trinnov is working with the âAmethyst zoneâ but when i selct a 5.1 or 7.1 output,
i only get still 2.0 output from the Trinnov âŚ
I guess it worked before, but as i only have the RoonReady sw some days and played a lot with my setup, i dont know 100% if that worked before, but iam guessing it have worked.
So whatz is the cause here ?
I have tryed with 5.1 and 7.1 and also âdownmix as neededâ or " Channel mapping only" on âplaybackâ and also to power down and up, no difference. Other options as âDSP engineâ also works- âonlyâ more the two cahnnels are not working.
So as far as i understand-
refer to TRINNOV support RoonReady offers that option to âupmixâ either a 2channel stream in the TRinnov or deliver a Mch stream ?
Please help
As far as I understand it, Roon maps the stereo to the left/right channels of a MCH setup and sends silence on the rest of the channels, as per the knowledge base. I do not think that Roon âupmixesâ anything.
Yes, i understand downmix. But iam talking about âupmixâ.
So the Trinnov Amethyst passes a mono or stereo source as 5.1 or 7.1 layout,
that is what i understand from the description, so then its a âupmixâ ?
Iâm sorry if I was not clear, but, the following is my understanding of how those settings work.
If you have âChannel Layoutâ set to 5.1 and âSend Stereo/mono content as 5.1â set to NO, then what happens is Roon sends signals out ONLY on the stereo left/right channel and nothing on the rest of them. This causes some multi-channel equipment to not play anything at all. In order to maintain compatibility and allow those players to actually play stereo music, the âSend stereo/mono content as 5.1â when set to YES, instructs Roon to send âsilenceâ on the other channels. Roon does not âUpmixâ to surround sound from a stereo source.
Is there any application/sw with Roon ready available or planned in the near future to make an âupmixâ FROM Roon ?
Iam asking as i want to use âupmixâ stereo sources as i have it current with my Meridian my audio chain.
But i want to remove the meridian processor and replace it with Trinnov, but Trinnov makes no upmix processing codecs/sw, they âonlyâ decode the current 3d home cimea codecs .
Just to clearify as i asked Trinnov and that is their answer about if Trinnov itself have âupmixâ processing:
Hello Robert,
I will clarify the situation on Trinnov general products, and I will talk about the Altitude later as it is a little bit different.
Trinnov doesnât have that kind of technology. It means that if you play stereo content, it will only play on Left and Right speakers. We donât âcreateâ some content to feed the center channel. We just simply reproduce the content with the higher fidelity possible.
The Altitude is a different products because it is a home-theater dedicated products, and so includes decoders : Dolby Atmos, DTS:X and Auro-3D. These 3D decoders, if included in the Altitude (Optional feature) has their own âupmixerâ. Each upmixer has their own algorithm and also their own limit. They are able to take a stereo content and upmix it on a 5.1, 7.1 or a 3D speaker layout (with ceiling speakers). There technologies wonât work on a 3 speakers (LCR) configuration.
These upmixers are more dedicated to a home-cinema use but also works on stereo content.
These technologies are not Trinnov technologies, so we donât really know what happen and what the recreated channels is containing. To use these up-mixers, the 3D Codecs option is mandatory.
Hey @robert_wistrela-- right now, Roon does not do any âupmixingâ, although obviously products that Roon streams to (like the 861) can.
Roon will be pass on the stereo content but as for whatâs possible with Trinnov after that, I think youâll want to talk with them if you have further questions.
