2. What is the recommended maximum distance from the side surround speakers to the back surround speakers?
3. According to Dolby's recommendations, the back surround speakers are not positioned as wide apart as the side surround speakers. If the back surround speakers need to almost as wide apart as the side surround speakers due to room constraints (almost in the rear corners of the room), will this be an issue in any way?
4. Is it easy for a newbie (who has never operated any sort of EQ or even auto-EQ) to setup and EQ a RS20i?
5. My (sealed) room is roughly 15 ft long x 12 ft wide x 9.5 ft high. I will have a single row of three seats. 7.1.4 will be good enough for a good immersive experience or should I shoot for a 9.1.6 setup with an Altitude32?
I will try to answer some of your questions, as far as I know it.
1. I cannot answer because I have never heard the Trinnov Altitude 32. I believe more in the DSP concept, even it is more difficult to program. I mean this by jitter, OS, which might not be truly real-time etc. If you download the code on a DSP, it does exclusively this, what the code says. There is no delay or other tasks to perform for the DSP but for the PC, this is different, the processor also runs the OS plus interrupts etc. The DSP is exclusive to it's tasks assigned. I don't know, what OS the Trinnov Altitude is running, is might be as well as for the RS20i Linux based. However, the RS20i is initializing the DSPs with code, when it is starting up whereas a PC works different. It starts the OS and then the processes, which are also audio processes. To make it short here, this is one of the reasons I believe that a DSP platform can be more true to impulses and can have more dynamics than a multipurpose platform. However, I also watched a video about a comparison of the Altitude 32 and the Datasat RS20i and the person - Lars Mette from Hollywoodzuhause.de - said that the Altitude is a master of spaciousness and the RS20i, if I am not mistaken, of dynamics. You can find the video here: http://www.takeoffmedia.de/magazin/s...leich2016.html
It is more than two hours and also includes other pre/pros. This company is also the main distributor for Datasat in Germany but they are also selling Trinnov. Audioguy wrote about the presumably drawbacks of the Trinnov and I agree to his point of view.
Please never forget, that both products are intended to be sold as 'installer' products, this means you have to pay extra for this service, except you buy them used. Then you have to rely on the service of the manufacturer, in case of Datasat. For Trinnov, I have no experience.
What I heard is, that the sound quality is quite similar but they have a different focus.
2. As far as I know, Dolby tells you something about angles and not about specific distances. Do as you like but keep the angles and read what westmd wrote in his excellent Atmos vs. Auro 3D setup post. I agree with this, because I did intuitively the same in my HT.
3. I guess this will be an issue, even I know a parameter to be set with conventional AVRs or pre/pros about the rear surronds being more than 1,2 m apart or less. This should be around 4 ft or less. The RS20i doesn't have this setting. You also have to calculate the initial surround delay by measuring.
I guess you know the Dolby setup drawings for 7.1 and I also don't have this exactly like Dolby requires it - I have all speakers on one axis, front to rear surrounds. The surrounds itself are 90° on the wall and a bit more outside this axis.
My impression is, that the rear surrounds should be closer together. It seems to me, that the old thinking of ES is still alive and somehow the rear surrounds are treated not as real stereo speakers, but this only my impression.
4. Clear answer: No! You have to read the manuals and especially understand the concept of the output presets, as well the input presets. This is unique with Datasat and not to be found anywhere else. By reading the manuals, you might be able to understand most of it but a thorough background in surround sound and sound equipment in general is very helpful. Sticking with the EQ issue, Dirac is as easy as Audyssey, if you don't want to do any special things - just use standards.
5. I would say that after listening to Star Trek Beyond in a 5.1.4 setup is more than sufficient for a very good immersive sound. If you have the space and also a height speaker friendly room and do not back-up from the additional power amps and speakers or additional AC outlets and active speakers, Dolby says that more speakers are better. The RS20i can do up to 10 Atmos speakers in the ceiling but I doubt, that the 16 channel version can do more than six ceiling speakers, by re-routing the additional subwoofer channels and the VOG channel. I haven't tried this, if this is possible I have my doubts.
However, for Beyond, I found a 5.2.4 setup already breathtaking. There may be other disks worth a try, I only know Beyond and this was really amazing in 5.1.4 and better than 7.1.2.
Hope it helps, please correct me somebody or tell your own experiences. Thank you.
