Alright I have 4 Sonos Amp. I have 2 Amps for my outdoor TV. One of my amps is being used as my surround sound. My family and friends love to sing karaoke and we just look for the karaoke version on YouTube through our Apple TV. I just bought a Yamaha AG06 3 channel mixer, BLX88 Shure Wireless Microphone Receiver with 2 Wireless SM58. I am planning on connecting the mixer to the line in option to the amp connected to my TV through HDMI ARC. And I would like to know if this set-up will work. Also are there going to be an issues? If there is, is there anything I can do to fix it. I'm trying to avoid have a huge PA system. I have my Sonos Amp connected to Polk Atrium 6. I'm making everything look very simple. I hate dealing with issues, not a very good when it comes to tech. I have a family member do all the install. And I currently like the setup we have it's amazing for movies and music now we want to add the karaoke completely the setup.
