?Denon®, the world’s leading manufacturer of premium home entertainment and personal audio products since 1910, announced today the launch of the Denon DHT-S217 full-range Dolby Atmos sound bar. The sleek DHT-S217 delivers superb clarity including crystal-clear dialogue with authoritative bass response from two onboard subwoofers that will certainly please both music and movie enthusiasts. The DHT-S217 also incorporates Dolby Atmos 3D audio technology for a lifelike, cinematic surround sound experience sure to elevate the performance of the latest 4K TVs.

“If you’re looking to vastly improve your TV’s built-in audio, look no further than our DHT-S217 sound bar,” said Trip Randall, Denon brand President. “The DHT-S217 transforms any TV into a complete home entertainment system thanks to its built-in subwoofers that pack a deep punch and powerful 3D surround sound, all at an accessible price point.”

At a scant 2-inches in height, the Denon DHT-S217 can be placed in front of the TV without obstructing the bottom edge of the display or it can be easily wall mounted. Though low-profile in stature, the DHT-S217 has been optimized for exceptional performance thanks to Denon’s century-long legacy of creating superb home entertainment systems.

Listeners can also choose to effortlessly stream their favorite music, with room-filling clarity, to the sound bar from a smart phone or tablet via Bluetooth. 

Easy to Connect and Control

The DHT-S217 easily connects to most TVs using the supplied HDMI or Optical cables, facilitating intuitive control of the sound bar volume using the TV’s remote. The 4K HDMI connectivity delivers stunning video with nuanced contrast, imaging, and brilliant colors—while the eARC feature enables music enthusiasts to enjoy rich audio playback on the sound bar from streaming apps built into their smart TV. The DHT-S217 offers a choice of four sound modes (Movie, Night, Music, and Pure), enabling listeners to choose the perfect mode for any occasion. The Pure Mode bypasses all surround processing and other adjusted characteristics for the most audiophile listening experience.

Denon Dialog Enhancer

The Denon Dialog Enhancer is a beloved feature that improves dialogue clarity with three different modes—ideal for movies or TV content where dialogue comprehension is paramount. The Dialogue Enhancer enables listeners to adjust the dialogue level without affecting overall program volume.
