If your TV lacks eARC/ARC, you can connect via HDMI IN plus optical or AUX depending on the TV outputs. Optical provides digital audio, while the analog AUX works with older TVs. HDMI with ARC/eARC is recommended for best multichannel support.

Product Description
Denon DHT-S218 — Powerful Dolby Atmos Soundbar
The Denon DHT-S218 is a compact soundbar engineered to elevate TV, movie, and music playback with immersive Dolby Atmos support, clear dialogue enhancement, and versatile connectivity. It blends Denon’s audio heritage with practical features for modern living rooms: eARC/ARC HDMI for high-quality audio return, optical and analog inputs for legacy devices, and Bluetooth (including LE Audio support) for wireless streaming. The bar’s slim profile and wall-mountable design let you place it in front of or beneath a TV without obstructing remote sensors.
Key features and user experience
Denon focuses on straightforward setup and reliable operation. The included HDMI cable and support for eARC enable multi-channel, high-resolution audio from compatible TVs. If eARC isn’t available, optical and analog inputs provide fallback options. A dedicated subwoofer output lets you add an active sub for deeper bass, while on-board DSP modes (Movie, Music, Night, Pure) tailor the sound to the content. Pure mode preserves source fidelity, Movie and Music expand spatial presence, Night compresses dynamics for late-night listening, and a three-level Dialog Enhancer improves vocal clarity.
Bluetooth pairing is quick, and the soundbar supports Bluetooth LE Audio for compatible devices (with Android 13+ and supporting hardware). Controls are accessible via the included RC-1251 remote, the bar’s top-panel buttons, or by learning commands from your TV remote; HDMI-CEC control is also supported for unified operation. Power and standby behaviors can be customized (Auto Standby, Deep Standby, HDMI standby link) to balance convenience and energy savings.
Design and installation
The DHT-S218 is lightweight and compact, measuring under 900 mm in width and weighing approximately 3.6 kg, making wall mounting straightforward using the keyhole mounts. Denon includes guidance on placement, secure mounting, and cable routing to avoid strain. The rear panel hosts USB (firmware/service only), AUX IN, OPTICAL IN, HDMI IN, HDMI (TV eARC/ARC) and SUBWOOFER OUT for flexible integration with a range of source devices.
Performance highlights
Expect clear midrange and intelligible dialogue from the Dialog Enhancer, believable surround impressions from Dolby Atmos-enabled content (subject to source and TV eARC support), and easy wireless streaming with modern smartphones. The option to attach a powered subwoofer extends low-frequency impact for home cinema enthusiasts.
Notes:
- Pure mode disables Dolby Atmos decoding; Dolby Atmos content will be shown as Dolby (except Atmos) in that mode.
- Bluetooth LE Audio compatibility varies by device and platform (iPhone does not support LE Audio; Android needs version 13+ and LE support).
- USB port is for firmware updates/service only, not for USB audio playback.
