Re: DOLBY ATMOS
OK, this is not going to work. Rick is right, and maybe Squadie also. I did some experimenting with my Oppo 203 DVD player and confirmed this.
I played a 4k Ultra HD DVD I have and tried 7.1.4 Dolby Atmos and 7.1 Dolby Digital Plus. With the Bose plugged in, I could select the 7.1 Dolby Digital Plus, but the Oppo would down convert to 5.1 Dolby Digital Plus. I disconnected the Bose and switched on the LG TV internal speakers and turned on Atmos (It's an Atmos capable TV). I was then able to choose both 7.1.4 Dolby Atmos and 7.1 Dolby Digital Plus, but both would down convert to 5.1.
So, I have concluded that the source is not going to send more than the sound system can handle. Now, if I were to sell my Bose and purchase an LG Dolby Atmos soundbar, it would probably be possible to do this and have the upward firing soundbar plus overhead speakers playing through an amp, but that's not something I'm going to consider. I love my Bose Soundtouch 300 more than I want Dolby Atmos overhead speakers, not to mention the cost factor!
