12 channel Atmos on a budget, 7.1.4 Guide

Can you/anyone please point to a resource on how to tune using room EQ wizard… I cant make sense of what you mean when its said:

  1. "spent time aligning all of the speakers?? and EQing them with REW?? ( what you mean by aligning, physical allignment, how to do measure the allignment needed)
  2. plus trying to figure out how to create a LFE downmix of all channels. ( didnt understood this at all)

Information for the 1 and 2

Thanks, I tried today to setup 7.1.4 but with multiple bluetooth speakers connected to macbook in place of using an 12 channel dac as its not available in budget at my place. Speakers worked but i got inconsistency in delay among various speakers, with max delay between wired and bluetooth ones.

I wonder is there a way to control the delay of bluetooth speakers or bring all them in sycn, After effects in audio midi in mac didnt help.

There is always a added or extra delay in Bluetooth speakers vs wired.
Signal is coded to be sent (most likely from analog to digital format) or just digital from Sending unit.
Actual sending phase.
Receiving unit then takes the signal and chances it back from digital → analog format until sound actually comes out of the speaker.

Plus there is always a possibility of interference and even more delay from other devices working on same 2.4Ghz range.
All the “work” varies how long it takes from Send → Receive → Sound depending of units but its pretty much impossible to tell “how long” it actually takes.
It could be 70ms then again it could be 130ms.

Bluetooth speakers systems with surround or multiple speakers usually have a “master” unit.
That handles the sending, so the delay is similar with all the speakers = sound comes out in correct time if no other interference’s.
There most likely is delay if using wired speakers as well with split signal. Wired always being the faster side so audio comes out first.

Changes that happen constantly in the Wireless side is the issue with delays and probably is not possible fix fully??
Specially if you pay close attention how the sound comes and when.

There might be some software available that handles the delays per unit but have not tested or done more research. Like this might be one.

Dont if there is similar to Apple thats available.

This is great

Thanks this help.

Hey Team,

I have a concern I am building in house 7.1.4 setup with Active Monitors and I am currently using focusrite audio interface I am quite confused about the REW. Should I have to calibrate each and every speaker through REW? I am still confused with the Speaker Calibration Stuff.

Hey @Krentus

Could you please explain little bit more about the calibrating using REW?

What are the steps do we need to follow and how we can apply those eq settings to our speakers if we are not using miniDSP can we do this eq settings with Audio Interface (FOCUSRITE)?

You should be able to use FAST Equaliser software with the Focusrite stuff for the EQ.

So basically you could measure the room with REW if you want.
And yes, all channels.

Then see results and try change the EQ to correct some room boosts, or peaks. Maybe correct some FR’s lost under the normal.

But these require some learning and testing to figure out. :slight_smile:

Hi everyone,
I am newbie and had only verbal knowledge. When I tried to learn, I had confused in how to connect all 5 DSP to single audio source.
I hope someone will clarify me.
Thanks in advance :smiley:.

Single graph with connections and explanations might been a nice thing.
Keep in mind. This aint newbie level… to set and configure ( first post + configuration ).

Anyone with more information please correct me. I think →

  1. you connect these 2X u2audio7-1 DAC to the audio source / being computer.
  2. each day gets a few set of 3.5mm to RCA cables coming out, these signals pass through the miniDSP 2X4 (two channels per miniDSP, channel 1 and 2), then into the Dayton speaker amp.
  3. Amps to speakers.

Plus read slowly and mindfully the first post concerning power and software + video.

Or just trash and forget everything all and look for any other solution that is much simple but little more money. Few good options as well in comments.

Just buy a real Dolby Atmos licensed processor… This is NOT Atmos

Wondering what this is then?

Not a Apple fan or user but Apple has Atmos support.
So it should be using Atmos codec and sending correct sound channels to correct speakers.

I was informed originally was “Apple Spatial Audio” lossy playback for Dolby Atmos material. Maybe that was not true or changed I don’t keep up with Apple.
I would hate for someone without an existing MACbook to try and go this route as “budget”.

True.
Also this “Apple budget” system is very complicated vs. one stop shop or standard AVR.
Now days with automated On/Off setups you might need to press 2 or 3 buttons to actually start playing the movies / music / games. Depending of course on devices and HT -setup design.
Minimun would be 1) Insert disk → then everything turn On automatic ----> 2) Hit play = Thats it.
3) adjust volume.

That convenience can cost few $ in my mind. Specifically the “daily using part” needs to be simple and easy.

Can anyone please help me with surround sound setup similar to this with dolby atmos on windows 11 I have 3 pairs of Edifier R1700bts speakers paired with DIY center speaker also I have creative X4 external sound card which has support for 7.1 descrete outputs

OSX can now be easily virtualized. For a few hundred bucks I can now have a 16ch setup. You aren’t going to get that anywhere “officially” for less than 5 grand, and thats just for the processing. As I mentioned before in this thread, this whole setup is intended for enthusiasts on a budget.

Its not possible. Windows doesn’t have any software currently that will allow you to aggregate multiple sound ouputs like mac does. You run a virtualbox of mac now though really easily. Linus Tech Tips has a tutorial on how to do it.

16 channels isn’t happening for anything less than 5 grand.

i dont think it even should happen.
It should not be 16 channels on a budget when you could have Good with 5 channels.
