Best way to get HDMI 7.1 LPCM into a MTRX?
Not sure if anyone who does some gamedev might know this..
Let’s say you already have a 7.1 monitoring system with MTRX, and you want to add a 7.1 LPCM source from a game console devkit or something, which is via HDMI. What’s the best way to get that into the system? I assume there might be some kind of HDMI to ethernet meant for Dante, which you could use with some kind of thru or splitter so that you can still pass HDMI video to TV. If so what would the latency issues be like for monitoring the sound with picture? That’s just a shot in the dark, i’m not too familiar with Dante.. or is there some other setup that would work? |

The "or something" doing a lot of heavy lifting here.
HDMI decoders/deembedders to multi-channel digital audio don't really exist for the obvious copy protection reason. |

Console HDMI to a Yamaha home theater receiver. It has 8 RCA preamp outs, which go to a rack unit that brings them to line level. 8 1/4” outs of that to cables which would take up a whole MTRX A/D I/O card. |

Ferrofish, Focusrite, Tascam have cheaper options than MTRX AD. Or find a used SSL Alphalink and go Madi into the MTRX. Or a used Apogee Rosetta 800 and go into the MTRX over AES.

Also, a development kit can disable hdmi (hdcp) encryption so this is more just about the easiest way to get hdmi’s 8 pcm channels into dante i guess..

Unfortunately that's the way the cookie crumbles. As pointed out you can find lower-cost outboard converters, but ~$2.3k for a 8-input card maybe just live with that. Stepping up to MTRX was never going to be a bargain. And I'll add there is a used AD card on Reverb ~$1.7k in the LA area.

Arvus sell a couple of products designed to do stuff like this. https://www.arvus.com
One that does straight HDMI to AES, and another that does Atmos over HDMI to a variety of I/O including Dante. The latter in particular is pretty expensive. Something like $5k.

Re: Best way to get HDMI 7.1 LPCM into a MTRX?
For 7.1, I use the return bitstream audio (Toslink optical) from my display going to a Dolby DP564 which decodes to AES3id outs. And then I use Neutrik AES/EBU impedance transformers to send that 75ohm unbalanced AES output into the MTRX 110ohm balanced AES inputs.
Nice thing is the DP564 accepts word clock from the MTRX. And since the audio is a return from the display, anything plugged into the display's multiple HDMI (or any application like DisneyPlus, Netflix, HBOMax) is fed back to the decoder.
