I used it to play video sync
recordings that I’ve made which were originally stored and played via my TiVO.
I sent the ‘sync audio’ signal to the piano via Bluetooth link.
I had originally used a long audio cable
fished through my walls & attic to connect and send the sync signal to the
piano when playing back the video. It had issues with noise and hum plus it was
also a pain since I always crawled under the piano to connect/disconnect the
cable when not in use since I was worried about surge damage to my Disklavier during
a thunderstorm.
I thought about pulling
fiber optic cables to mitigate surge damage worries but when pricing the media converters
needed I settled on using a Bluetooth link instead. (Using a Bluetooth stereo
audio transmitter at my Tivo and the Bluetooth stereo audio receiver under my
piano.)
I also used the Bluetooth link for playing back the video sync recording I uploaded on YouTube many years ago. I don’t play my video sync recordings much, but now use it frequently for Disklavier TV to wirelessly send the audio sync to the piano from my Surface Tablet, Phone or my Sony Google TV box connected to my home theatre system.
