The LG 75" Class 70A Series QNED AI 4K UHD Smart webOS TV (2025), Model # 75QNED70AUC, is a Bluetooth-enabled TV which can be connected to a Surround Sound system in one of three ways. It can be paired wirelessly via Bluetooth if your surround sound system supports Bluetooth. It has an HDMI eARC port (HDMI 2) that can be connected to an HDMI eARC or HDMI ARC port on an audio system if your surround sound system has one, or it can be connected to an Optical Digital Audio Input on an audio system if your surround sound system has one, via the Optical Digital Audio Output on the TV. If your in-wall speakers are already connected to your surround system, then all you need is to connect the TV to your surround system using any of the above-mentioned methods...^Ivan.
