I recently purchased an Optoma UHD65 and cieling mounted it in our family room next to our Kitchen. I am not happy with the onbaord audio (surprise :-)...but it's just a casual viewing environment for us to watch during breakfast or after dinner...but it's still not good enough. I am looking for a small amplifier recommendation that can sit on top of the cieling mounted UHD65 that can handle 2 hdmi inputs and then power some in cieling speakers. I have looked at sonos and rialto but they don't have 2 hdmi inputs and 1 hdmi output.

Any suggestions?

There is nothing that I'm aware of which can do this on the market at all. You can try looking on a more audio centric forum like Audioholics, or try AVS Forum, but it isn't something I've ever heard of.

To get audio, you need to convert it down to a 2.1 audio stream, which requires digital to analog converts and digital signal processing, which all costs a bit of money. As well, most people want additional audio inputs and capabilities beyond just stereo audio.

To be fair, your projector does have built in audio outputs for 2.0 stereo, so with some decent speakers and some amplification you can get decent stereo audio directly out of the projector using either optical audio or analog stereo audio (3.5mm analog audio out). You would take that audio connection to an amplifier and up to ceiling speakers.

Instead of looking for a mini-amp with HDMI, you just need a amplifier which has enough power for some ceiling speakers. Then connect the audio out of the projector into it. The audio output of the projector is perfectly fine to drive external speakers. Just go into the projector's audio settings and turn off the internal speaker inside the projector.

Something like this may work, but read reviews of mini power amplifiers to see what has good reviews and enough power.

You would come out of the projector with this cable and into the amplifier...

Make sure to put any ceiling speakers towards the front of the room where the audio should come from. I would use angled speakers if you can get them.

Thanks very much for your response. I came across the Rialto 400/600 and am looking more closely at them as an amp candidate with optical inputs. https://www.audiocontrol.com/home-audio/zone-amplifiers/rialto-600/ Any thoughts on that as an alternative? Overkill?

8x5x3?

I think that's a great looking product that really hits a lot of what you are striving for.

The optical audio output of the projector should be perfectly fine, as would be the stereo analog outputs, but you really should be good with this product.

I will try to put this in my back pocket for reference in the future as an option for those who are looking for something decent.

Please be aware that in-ceiling speakers should be located towards the front of the room near the screen and should use angled woofers to help get the audio directed from the front of the room towards the listening position.

Yup...thanks very much for the suggestions. I will post the results once I get it implemented. I am in the process of waiting for a replacement projector. Unfortunately the new one I received has a "lisp", they think due to a defective sound board...so I am waiting for that replacement to show up and test that before investing in the audio portion of the project.
