Dolby Atmos After 7.1.4 - Part 1 (2023) (2023)

A little over a year ago, I started experimenting with ways to expand my Dolby Atmos surround sound system beyond the 7.1.4 limitations of current consumer hardware. My constant quest to get the best Atmos experience in my home has recently prompted me to make an additional upgrade. My home theater system is so complex these days that I actually need three A/V receivers running simultaneously to drive all my speakers.

In most home theaters, 7.1.4 channels will suffice. While the Atmos format (like its rival DTS:X) can support additional speakers, there's not much demand from consumers, and there's not much pressure from manufacturers. High-end boutique offering only $37,000 modelTrinov Altitude 32Will decode more than 11 channels at a time.

However, for some of us, the quadraphonic height restriction isn't enough to fill the top of the room with sound. My own home theater is a long room with plenty of room behind my seats. Combined with the low ceiling, it was difficult to convincingly reproduce sound overhead with just four speakers (two at the front of the room and two at the back). The problem was compounded by the fact that the placement of the speakers when I was building my home theater (before I thought about surround sound) wasn't ideal for Atmos. The speakers are now held in place by the wall and ceiling wiring, and I can't move them without remodeling the room. This is not an option at all.

The best solution is to install an additional speaker centrally between the other vertical channels (top middle position). Unfortunately, the asking price for the Trinnov processor is way beyond my budget. I need to find a way to manipulate similar effects at a fraction of the cost.

first try

II wrote an article last yearExplains how I cobbled together a complex system (jokingly called "Zatmos") using a second A/V receiver to plug in extra channels on my ceiling. I recommend reading that article to get a basic idea of ​​how this sort of thing is possible.

Even then, I wasn't the only one experimenting with this, and I knew my Zatmos system wasn't as ideal as I'd hoped it would be.An AVS Forum, a member named Scott Simonian went even further, using a total ofThree A/V receiversConsistently created a 7.1.6 setup (affectionately known as "Scatmos") that more accurately matches the intent of the original Dolby Atmos mixer.


For a while, I decided not to go that far. The complexity of installing, wiring and configuring three A/V receivers seems like overkill to me. I feel like the results I'm getting with the Zatmos are good enough for most jobs, and I have a selfish pride that I've figured out a way that only requires one extra receiver instead of two.

However, over the past few months my attitude has changed and I've become less comfortable with my Zatmos setup. Ultimately, I knew that if I was going to do this, I had to get it right.

go all out

The silly nicknames Zatmos and Scatmos could be more formally grouped under the heading "Dolby Atmos Extended." I want to make it clear here that I am not developing the Scatmos process. Credit goes to Scott Simonian and others at AVSForum for helping him out with this issue. With your permission, I just wanted to explain it here.

Although their setup is extremely complex, one of the advantages of these experiments is that they are relatively inexpensive to assemble. While your primary A/V receiver should be a Dolby Atmos (or DTS:X) model capable of decoding 7.1.4 channel sound from a Blu-ray or UHD surround audio soundtrack, your secondary receiver doesn't need to be as fancy ..any receiver with at least Dolby ProLogic II processing capability will work. (If you're using multiple secondary receivers, I recommend that they be identical to each other.)

With a bit of patience, I picked up a pair of used Marantz SR4400s for under $100 each while looking at ads for sale on my local Craigslist. This is a low-cost, entry-level (or close to) Dolby Digital/DTS model from 2003. It's so basic that it doesn't even have an on-screen menu system. I have to use only the front panel display for setup. The receiver does not have HDMI and cannot handle lossless Dolby TrueHD or DTS-HD Master Audio signals, but this is not required. All you need is a pair of stereo analog inputs (any receiver will have them) and ProLogic II.

Simply finding a place in my system to put another A/V receiver was much more difficult than I'd like. Since I didn't have enough rack space for my main gear, I had to remove all components, disassemble the rack, rearrange the tiers, put most of the gear back together, and reconnect. Then I had to do the same for the second shelf to add a layer. My Blu-ray and HD DVD players, which used to be on the main shelf, have been moved to a second shelf so I can keep all my audio gear together so the speaker wires can run through. That in itself is a huge pain.

Once that's done, here's the basic idea behind Scatmos: You want six in-ceiling speakers in the front, center, and rear ceiling positions. (The sketch below does not represent my personal speaker design, but I drew it this way to show how it works.)shouldFinish. ) Your main A/V receiver will be set to decode your maximum 7.1.4 channel set to top front and top rear.

All four vertical channels should be routed to the analog preout connections on the main AVR. You should not connect any speaker cables to these channels on the main AVR. For all height channels, the speaker wires will only be connected to the auxiliary AVR.

The pre-outs of the upper left and rear upper channels go to the left and right stereo inputs of the AVR 2.

On the AVR 3, the front outputs for the upper right front and upper right rear channels will go to the left and right stereo inputs (inverted from the AVR 2).

If that sounds confusing already, trying to keep things in order when connecting cables can be really daunting. I highly recommend drawing a diagram showing where it should be placed.

When functioning properly, each downstream AVR subs should receive a stereo signal consisting of the front and rear, and use any mono information common to both to form a mid channel between them (much like a ProLogic II would Pull a channel center for dialogue). Normally located between the left and right speakers at the front of your room). So you get six channels of height information from four originals.

That's the theory, reduced to its most basic elements. Actually, getting it to work after the connection is established is a bit of extra difficulty, which I'll cover shortly in Part 2.
