Split Atmos Channel?

4919 Views 13 Replies 6 Participants Last post by  Vengadesh
So, I have a newer 7.1 channel receiver, which will allow me to run a 5.1.2 system in my future dedicated theater room. However, I've heard/read that it's a much better experience to have 4 Atmos speakers up in the ceiling as opposed to 2. If that's the case, can I just split the two Atmos channels using speaker selectors switches with protection/overload on them? There's only two actual discrete Atmos channels for HT, correct? So I'm thinking, if I just split those two channels for 2 sets of speakers, I could achieve that without having a 9.1 receiver.

Am I thinking of this all wrong (probably the case)?

Let's separate channels from speakers. Splitting the same channel to two speakers doesn't give you stereo.

2 speakers above you will let you hear left-vs-right separation overhead. 4 speakers above you will let you hear left-vs-right AND front-vs-back movement overhead. So there is a definite advantage to 4 heights.

However, if you're splitting the same 2 height channels between 4 height speakers, then you won't hear any front/back movement (both pairs of height speakers are playing the same info).
Agreed, there would be no front-back between the Atmos speakers. However, I have a fairly long and narrow room that will have multiple rows so my thoughts were that if I had two sets of left and right Atmos speakers, it might improve the overhead sound since I will still have the surround channels behind the rows. Or do you think that having the duplicate pairs of left right Atmos speakers will muddy the front to back effect even though I have the back surround channels?

Arraying a single pair of channels to multiple pairs of speakers shouldn't be a problem (done in movie theatres all the time). Will give you more even coverage.

Back surround speakers are in the base layer (around you). Height speakers are in the height layer (above you). Let's not confuse the two layers. Arraying the channels above you won't change the front/back effect around you.

The only "front to back effect" would be from the floor speakers. If you want "front - back" overhead Atmos effect, you need at least 9CH AVR that can do 5.1.4.

What you're suggesting is no different than someone that splits the floor side surround speakers with multiple rows of seating.

All you're doing is expanding the overhead "right - left" overhead effect. Doubt it's worth the extra effort.

Return the 7CH AVR and pony up for a 9CH model (eg. 2019 Denon X3600H).

Which receiver do you have. You may have pre-outs and just need a separate stereo amplifier for the other 2 Atmos channels and use the receiver’s amps for 2 Atmos channels and the main 5 to get 5.1.4

Unfortunately, AFAIK, there haven't been any major brand 7CH models released that can expand to 9CH since 2015.

You are probably right, I have not looked into it but I know the Anthem MRX720 can do it (11.2 preamp and 7 channel amp) as I was looking at that a while ago but just now checked Marantz and Yamaha they could not. Maybe very few can do it unfortunately.

Agreed, would have preferred a 9 channel receiver, but I was able to score a 1 year old Yamaha RX-A870 for $200 with an extended 4 year warranty, so I couldn't pass that up as I still have many other things to buy for this theater build!

Splitting the channel won't be useful dont even bother. Also I agree if you cant go 5.1.4 dont bother with 5.1.2. 5.1.2 is almost worthless over 5.1. 5.1.4 is awesome compared to 5.1

If you want atmos just bite the bullet and get a receiver that supports at least 5.1.4

That would be 2 year old and important to note that only 3 of the 8 HDMI inputs are HDCP 2.2. :(

Hi bro same doubt for me I have 9.1 home theatre I like to play 5.1.2 any idea you have bro any software you have long days I confused this method

Which software you use for that I have 9.1 home theatre how I play 5.1.4 on this system please help me
