5.1 Playback in 2 Channel (1 Viewer)

[Music lover10]

Currently I have an Oppo UDP 205 running through Rotel RA 1572. L - R speakers are B & W CM10 S2.
TV is Sony 77" A9G OLED.

My question: Do the 5.1 audio mixes (e.g. District 9) playing through my decidedly 2 channel set -up simply mix down automatically?
Dialogue seems to be favored in the mix-down. Which is a good thing. A few Blu-rays, like operas and orchestral concerts, offer a 2 channel
option. But few movies offer a choice.

Is my only option to buy a new 5.1/7.1 audio amplifier? Yes. Sometimes there are stupid questions......Any suggestions? Comparable
to the Rotel? It would be nice to take advantage of the many SACD's I have including vintage 3 channel from the 50's/60's.

Pretty sure I wouldn't be able to take optimal advantage of the movie multi channel set up as the room is 14'x 17. Sounds okay to my desiccated ears.
Hearing aids help a great deal.

Thanks for any guidance.

As long as you use the Oppo's dedicated stereo output you should be fine. It will mix down whatever it's fed to two channel. Don't use the multi-channel surround outputs, because those will assume you have the surround and center channels, which you don't.

Thanks for this. I had always assumed such but curious.
