A:Answer Hi Chris, you may either hook up your Apple TV to this receiver or directly to the TV. AirPlay works like Bluetooth, simply pair your device (iPhone, iPad, iPod or in an iTunes Library on your computer) to the receiver via AirPlay to enjoy audio content. Your iPhone 6S will work with this setup. You may refer to page 98 of this link for more information: https://docs.sony.com/release//Help_4686526113.pdf Thanks, -Mark
