Right, so judging from the 3D diagram of speaker layout you tell Trinnov exactly where each of your speakers are located in 3D space, the exact measurements away from listening position & angles? It then will mix the contents of your surround movie into those speakers in the best way it sees fit to maintain the correct intended 3D audio positioning? So you can just keep adding more speakers and putting them where you want (& telling it their location) up to the max amount that Trinnov supports and Trinnov then does all the processing?
Almost. YOU don’t have to tell it. The specialized quad microphone MEASURES it for you. Think “triangulation” but since it’s 3D, you need four measurements not three.
There are issues when it cannot measure things due to reflections, noise, etc. but yes. It’s the only setup that can distinguish between an LCR standing shoulder to shoulder 10 ft from MLP to one that is at Dolby reference locations, to one that is just ceiling speakers, etc. Other systems with mono mics only know distance.
3D Remapping does a lot of what you say. It clearly works better with Atmos dynamic objects than it does with fixed bed layer type stuff.
This is why Trinnov accounts for the big bucks.
Oh, and yes. You can add as many speakers as you want *within the context* of the model you buy. Altitude 16 is 16+4. Altitude 32 can be purchased with only 16 channels or can go up more.
Altitude CI is all digital and can go from 8-48 channels depending on what software license (need to double check those numbers)
