Help me hook up my Disklavier to my stereo and TV

[Lawrence Kellogg]

I have a Yamaha Disklavier DYUS5. I have the Disklavier hooked up on my Wifi network so I can play back DisklavierRadio and purchased Pianosoft titles. That's all good.

I want to add in video playback on my TV and audio playback through my stereo, which has a preamp/app/DAC, and two floor standing speakers. Oh, I also have an Apple TV connected to the TV, and I do have a headphone cable output that can play the TV audio on my stereo.

Now, there is a box on the back of the DYUS5 that has Omni input and output RCA plugs.

I also have an iPad Pro that does not have a 3.5" headphone output. I know one way to hook this up would be to use a headphone output jack to a Logitech Bluetooth adaptor to the audio in on the Apple TV but I don't have a headphone jack.

Can DisklavierTV run natively on the Apple TV or must it be screen shared from an iPad?

It's all very confusing, lol. It seems like I have to go Bluetooth out to an adaptor which will plug into the Omni inputs on the Disklavier and then connect the Omni output with a long enough RCA cable to the input on the TV? which could then send output to my stereo? Should I try some wireless transmitter to the stereo? 

My stereo and TV are about 20-30 feet away from the piano.

Any thoughts on the best way to hook this all together so I can watch the video on my large screen TV and get the best audio on my two channel system, and listen to the piano at the same time? 

Thanks!
