All, Im nearing the completion of the HT construction. The rough speaker layout is attached below. For now I am going for a 9.1.8 (2 subs but running off CSub with a split cable) setup but at some point with the added speaker modules want to get to 11.4.8. Yellow doted rectangle depicts the soffit/bulkhead that goes around the room.....the heights and tops are mounted there and tilted appropriately. For now I have been using the following link from Dolby as a guide to speaker setup www.dolby.com/siteassets/about/support/guide/setup-guides/11.1.8-mounted-overhead-speakers-setup-guide/sell-sheet-11.1.8-mounted2.pdf The issue I have with the dolby setup is that its depicts a single row of seats. Having said that it seams logical that each row have its own Tops? So my questions wrt the overhead and height speakers in the context of using an RMC-1: - What can the RMC-1 handle today in the way of flexibility in defining the .6 speakers? Is it L&R Front Heights, L&R Tops, and L&R Rear Heights? Something else?
- Depending on what the answer for bullet point 1 is, should my tops for each row carry the same L&R signal ie basically use a split cable for left yellow and purple boxes in the diagram and same for the right yellow and purple boxes
- Should I simply wire up the tops on each row to the RMC-1 L&R Front Height and L&R Rear Height outputs of the RMC-1 and not wire up my front and rear heights (green and orange boxes on the diagram) ie only have purple and yellow boxes active and then connect my subwoofers to the RSub/HT/LSub/Ht ports until the add on cards are available (9.2.4)?
Anyway I hope this makes sense.  |

Anyway I hope this makes sense. On a serious note: Aren't the ceiling speakers too far apart? Although they are meant to be in line with the front L&R (which are very far apart in your case and toed in to compensate but I guess the screen is the cause of that) however, ceiling speakers are very minimally directional and only tilt 20 degrees or so. I worry that the midline sweet spot seats will not be under the sound umbrella for those ceiling speakers and could miss out completely and a better compromise is to move the ceiling speakers in line with the outer seats. (These sets can never get great left and right ceiling audio anyway as it will only be directional for the midline seats The RMC-1 allows for setting any of the 6 height speakers (3 pairs Front, Middle and Rear) as Top or Height. 9.1.6 makes sense until the long since promised additional channel modules are released |

Dolby defines the requirements for the .6 as top or cieling speakers, not heights. I made this mistake at first too... ATMOS by definition requires cieling speakers

So what are the heights in the document I linked (for ease I have extracted the diagrams and circled the heights below)? Are they simply tops, instead above the front and rear bed speakers? How does the RMC-1 handle them ie what are they set to? In the current .6 setup the RMC-1 can handle, should I do the following with my 8 speakers: - connect the tops aligned to my two rows of seats to the RSub/HT/LSub/Ht outputs using a splitter
- connect the front heights to LF Height/RF Height output on the RMC-1
- connect the rear heights to LR Height/RR Height output on the RMC-1
Thx all.  |

The round circles are the top speakers... as for how to configure it I am not exactly sure. I think you're right in your configuration but I will leave it to someone who has configured 9.1.6 to give you a difinitive answer

Thx all. Those are indeed Front Heights and Rear Heights used to supplement the four ceiling speakers 10&11 (Front Top and Rear Top) This is the only time when height speakers are used in Atmos - to augment already established Top speakers (ceiling or Dolby Enabled) Dolby names them in the document if you look at the key code numbers in the circle next to the speakers (9&12)  |

Am I correct in the above three bullet points in mapping my 8 overhead speakers to RMC-1's X.Y.6 capability as it stands today? Jim |

jim80z Without upgrade modules, as you know, there's not a way to use more than x.x.6. Splitting Heights is not something I would want to do. But, if I were going to split a Height channel it would be the Top Rear. So this would be: Front Height:: Sm Top Front
Left/Rear Sub:: Sm Top Middle
Rear Height:: Sm Top Rear, and split for Sm Rear HeightThis way you can use the Rear Heights - if you like how it ends up sounding - until the modules become available.

I agree about splitting/duplicating signals though - Atmos generates directional audio so having it from top rear and rear height could be odd and it may be better to leave two of the speakers fallow for now (And start saving to buy a Trinnov or Storm 32 channel processor in 2025 in case the RMC-1 expansion modules are still coming soon or not what you hope for......) |

^^^^ Trinnov !  I'm gonna sell the rest of my stuff to get one! Then I'll just need speakers, amps, cables, . . . . maybe I'll keep my cables. Seriously though, I downloaded the Trinnov manual to get a sense of how they deal with the immersive speakers. I did the same with Wilson Subsonic subwoofers, which is a great read on subwoofer setup. |

Yup agreed mark which two in my set would you drop 2nd row seat or rear? Anyone from emotiva have any guidance? |

I would leave the Rear Heights out of the equation and run a 9.1.6 setup until and when extra channel modules arrive for your RMC-1
The 6 ceiling speakers are near optimal placing for an Atmos setup in a front to back arrangement (for the front row of seats for sure, and it is your home theatre so that is your seat dead centre, right!) so that will be awesome
Speakers can be pretty directional in sound with low dispersion and ceiling speakers cant really be pointed properly at the listeners.
.
I was walking through Leicester Square yesterday around 7pm (In central London and pre-COVID always PACKED with people but now it feels curiously unlike my city, and like a scene from 28 Days Later!) and could hear and see a busker about 20 metres away playing a horizontal guitar and singing using a typical guitar monitor.
I then simply walked past a shop with a ceiling speaker mounted in the porch and instantly got their (cruddy!) music playing which drowned out the busker. A few steps on and I could hear the busker again. Literally a narrow angle dispersion from this one single speaker.
Having just installed two ceiling speakers and toed in the tweeter units to point at the sofa, I again wonder about low ceiling heights like we have in the UK (Although mine is an above average 2.8m) and wide separation of quite directional, low dispersion speakers, what each listener gets

2.8M is above average in Canada too. Mine are closer to 3M. What's the average in the UK?
My childhood home was glorious with a cathederal ceiling vaulting to over 4.5M With glass from floor to cieling in one corner (glass on two walls.) It was at the top of a hill, and you could see all the glass clearly as you approached the house coming up the street. At Christmas, it was quite a sight with a nearly 3M tall Christmas tree placed right in the corner. It was glorious, but I am not sure I would want to deal with the acoustics of such a room now!

Mine are box type on pan & tilt mounts attached to the soffit edge. So directing any of the eight speakers is no issue. Ceiling height is 2.7m and the soffit takes away 23cm of that. |
