System Integration
The Denon DHT-S517 is designed as a complete soundbar-and-subwoofer solution for television, movies, gaming and music. A compatible television can connect through HDMI eARC/ARC, while the additional HDMI input can accept a compatible 4K playback device. Optical and 3.5mm analogue inputs provide alternatives for other televisions and audio sources, while Bluetooth enables direct wireless music streaming. The included wireless subwoofer handles dedicated low-frequency reproduction, so no separate AV receiver or external amplifier is required.
