Soundbar Speaker & Sub System: As today's flat-panel TVs get thinner and thinner, so does their sound quality. Denon's HEOS HomeCinema (HS2) soundbar speaker & sub system will transform your flat-panel TV into a home theater that will envelop you in rich, room-filling sound; clear mids and detailed highs from its multi-driver high-fidelity soundbar, plus deep bass from its wireless subwoofer. Simple to set up and easy to use, the Denon HomeCinema (HS2) lets you enjoy powerful, dynamic audio from your favorite TV shows, movies, games, and music.

• Active Soundbar Speaker: The HEOS HomeCinema (HS2)'s soundbar speaker features bi-amplified tweeters and mid-woofers with advanced DSP processing delivering clear audio especially in the vocal range. There are two 0.75" treated soft-dome tweeters with neodymium magnets that deliver extended treble response and wide dispersion. There are also dual 5" x 2" rectangular mid-woofer drivers with composite Kevlar cones and double magnet motor system for higher efficiency and linearity. Each driver is powered by its own Class D amplifier with digital signal processing for great sound at any volume level.
• Wireless Powered Sub: The included wireless powered sub features dual 5.25" woofers powered by a built-in Class D amplifier and a rear-firing port that work in tandem to deliver powerful deep bass with flat response and low distortion thanks to precision DSP audio tuning. You can adjust the subwoofer volume independently from the system volume.

Note: Do not listen to this system and your TV's built-in speakers simultaneously. Make sure to turn off your television's speakers. If your TV does not let you turn the speakers off, then mute the audio from the TV's speakers.

Advanced 32-Bit DSP w/ Dolby Digital & DTS Decoding: The HEOS HomeCinema (HS2) features the same powerful 400 MHz 32-bit floating point DSP engine found in Denon's AV receivers that delivers true wide range high fidelity audio, for maximum enjoyment of TV shows, movies, and your favorite music tracks. The HEOS HomeCinema (HS2) supports Dolby Digital, DTS, and Dolby Pro Logic II through its HDMI jacks and Optical/Coaxial digital inputs. It also supports Dolby Digital Plus via HDMI.

Virtual Surround Processing for Movies & Music: Exclusive Virtual Surround processing decodes discrete multi-track surround sound channels and uses advanced psycho-acoustic DSP processing algorithms to deliver an immersive surround sound experience with precision front sound-staging and enveloping surround sound, without the need for side or rear speakers. Movie and Music modes let you choose the best audio performance for blockbuster movies and your favorite music tracks. The HEOS HomeCinema (HS2) also offers additional audio settings to improve your listening experience.

• Dialog Enhancer: Dialog enhancer improves dialog intelligibility; ideal for movies and TV shows with complex audio soundtracks when it's often hard to discern what performers are saying.
• Dynamic Bass Boost: Denon's proprietary Dynamic Bass Boost provides advanced frequency and dynamic range tailoring to deliver deep bass while preventing distortion due to excessive overload.
• Night Mode: Night Mode lets you listen at reduced volume levels, letting you enjoy the full range audio experience without disturbing other family members. The Night Mode can be activated in stereo mode, as well as with any of the three available custom sound modes.

HDMI 2.0: Featuring one HDMI input and one HDMI ARC output, the HEOS HomeCinema (HS2) incorporates an advanced video section that features the HDMI 2.0 specification; including support for 4K/60 Hz Ultra-HD video with HDCP 2.2 compatibility (a requirement for 4K Ultra HD copy-protected content), 3D video, and ARC (Audio Return Channel). This system does not support HDR.

• 4K/60Hz: The HEOS HomeCinema (HS2) supports up to 4K (3840x2160 pixels) video @ 60 frames per second on all of its HDMI inputs and output. It will also pass a 480i, 480p, 720p, 1080i, or 1080p video signals via HDMI. There is no video resolution upscaling.
• HDCP 2.2: All of the soundbar's HDMI jacks support HDCP 2.2, which fully complies with the latest copyright protection standard for 4K video transmission.
• 3D Ready: The HEOS HomeCinema (HS2) supports 3D video pass-through (720p/1080p only) from connected 3D-compatible Blu-ray, games and broadcast devices to 3D-compatible TVs (all 3D components must be connected via HDMI). Special eyewear will be required for viewing 3D content.
• ARC (Audio Return Channel): This feature of the HDMI output allows audio to be sent from your ARC compatible TV to the HEOS HomeCinema (HS2) through the same HDMI cable already being used to send audio and video to your television. This eliminates the need for extra cables connected to your TV.

Note: The ARC-enabled HDMI input of some TVs will only pass 2ch PCM from devices connected to the TV via HDMI or analog, so we recommend that you connect your Blu-ray player or Satellite/Cable box to the HEOS soundbar directly; and then connect the soundbar's ARC-enabled HDMI output to your TV's ARC-enabled HDMI input. This setup will give you with the best overall sound performance.

Digital & Analog Inputs: In addition to HDMI connectivity, the HEOS HomeCinema (HS2) is outfitted with digital (optical/coaxial) and analog (stereo minijack) audio inputs.

• Optical & Coaxial: For TVs without ARC via HDMI, you can connect the HEOS HomeCinema (HS2) via one of the two available digital audio connections; both optical (toslink) and coaxial (RCA) digital audio inputs are provided. These digital inputs support 2ch PCM and 5.1ch Dolby Digital/DTS.
• Minijack: Additionally, Denon has included a stereo analog minijack (3.5mm) input jack that lets you connect the HEOS HomeCinema (HS2) to your TV without ARC or a digital output, or to a portable music player. This connection only supports 2ch PCM.

Note: The digital optical output of some flat-panel TVs only sends an audio signal in 5.1ch when receiving Dolby Digital/DTS surround sound from the TV's built-in tuner, network connection, or connected USB device; and will output only 2ch stereo from sources connected to the TV via HDMI, or RCA (like your Blue-ray/DVD player or satellite/cable box).

USB Port: The HEOS HomeCinema (HS2) is fitted with a rear-panel USB (type-A) port that allows you to enjoy a variety of high-resolution and compressed music files from a USB mass storage class memory device, such as a USB thumbdrive (formatted in FAT 32).
