Rear surrounds, mono or stereo?

Are the REAR surrounds, (on a 7.1)even though there are 2, mono? Or they are indeed stereo?

Thanks

All surround speaker signals are currently designed to be independent of each other. This allows the person mixing the sound to have the sound field shift side to side & front to back.

I hope this is helpful.

As Jim said they are discreet.

Awesome, and your timing is perfect as we are installing them now lol.

Thanks a million guys

I think some of the early rear surround options were mono, tho that's been a while.....

Correct. The original surround sound was Dolby Pro Logic, an analog format derived from a two-channel (stereo) signal. The rear channels were mono, comprised of a signal out of phase with the front left and right.

I was more thinking of beyond that point, e.g. 6.1 ....I wouldn't call surrounds in a 5.1 setup as rears either.

In those days, my surround channels were actually behind the seating and facing forward, as what was what worked best at my house. Sounded great, actually.

Yes, I seem to recall something about the sixth challel in 6.1 being a mono derivitive of the two surround channels.

Well, it was mono more because it was just the single speaker for "rear" surround. Think some early avrs allowed you to have dual rear surrounds but still mono depending on codec....been a while

In the olden days I had a Sony Receiver that was 6.1 in the Games Room, and later another one that was 7.1 but had an option to run a "center rear" surround => as in 6.1 which I did: as I didn't bother to go to 7.1. When we remodeled the Games Room in 2018 I went to Atmos and a 7.2.4 setup. This thread is just like walking down Memory Lane...

In a 7.1 surround sound setup, the rear surround speakers are not mono; they are stereo. Each rear surround speaker (left and right) receives a distinct audio channel, providing spatial separation and creating a more immersive sound experience. This enhances the effect of sounds moving around the listener from different directions.

Thanks for that, as I said in maybe this thread, I am reinserting myself in multi channel sound after a slightly long pause. SO, it was like that back in the day lol.
