Experience 3D immersive sound with the SR-B40A 200W 2.1-Channel Sound Bar System with Virtual Dolby Atmos from Yamaha. When connecting to a compatible TV via HDMI ARC/eARC, the SR-B40A uses Dolby Atmos decoding and Yamaha True Sound technology to envelope you in sound from the latest video games, streaming video, and Blu-ray discs. Additionally, a digital optical input is available for Dolby Digital sources without Atmos, and a Bluetooth 5.1 wireless input provides 2-channel wireless streaming from compatible devices. Control the system and adjust the settings with the included remote or free mobile app for iOS and Android.
