True surround sound
Soundbars offer a great step-up over your TV’s speakers but they still can’t beat the immersive sound of an AV amplifier like this Denon AVC-S660H. With 5.2 channel Dolby TrueHD and DTS-HD Master Audio, you get surround sound that’s pin-sharp in detail and totally enveloping – just like at the cinema.
Ready for 8K – with three 8K HDMI inputs
Featuring three, dedicated 8K compliant HDMI inputs and a matching output, this Denon AVC is ready for the next generation of TV and gaming. Not only does the amp pass through 8K/60Hz signals, but it also upscales HDMI signals to the 8K standard, too – helping you make the most of your 8K TV with 4K UHD media.
Serious about gaming
The latest HDMI support also marks a big improvement in gaming. 4K/120Hz and VRR (Variable Refresh Rate) support maximise resolution and clarity. Quick Frame Transport (QFT) and Auto Low Latency Mode (ALLM) help eliminate lag and frame tearing, giving you a smoother, more responsive gaming experience.
Support eARC (enhanced Audio Return Channel)
As part of the HDMI interface support, eARC is now standard. This enables uncompressed audio transmission from your TV, back to the Denon AV amp. This is ideal for getting the best audio from any smart TV apps and services you may use.
Supports Dolby Vision, HDR10+ and Dynamic HDR
Equipped with a flexible 6 in/1 out HDMI interface, the AVC-S660H supports a wide range of High Dynamic Range video formats. These include Dolby Vision, HDR10 and HLG. It also supports HDR10+, which enhances picture realism by sending dynamic Meta data to your TV, as well as Dynamic HDR. In short, whatever the format used by the film, game or stream, the Denon supports it.
Works with your voice assistant
The AVC-S660H is compatible with Siri, Google Assistant and Alexa, making it widely compatible with your choice of voice assistant. For Alexa or Google Assistant control, simply download the HEOS app. Pair your Echo device if you’re using Alexa and you’re good to go. For control via Siri, simply link the amp via Apple AirPlay 2 and enjoy voice interaction and AirPlay 2 multi-room support.
HEOS built-in - for the finest multi-room audio
HEOS multi-room music systems connect together by dual-band Wi-Fi, making them easy to set up with your existing home network. Up to 32 HEOS units can be set up at one time, ensuring even the largest of homes are covered for multi-room music. With HEOS already built-in, the AVC-S660H is ready to go as a single 'zone' without any further adaptors.
Control it all with the HEOS app
Once you've set up your HEOS speaker system, you can stream music effortlessly via the dedicated HEOS app. Available for Apple iOS and Android, the app not only lets you stream your stored music but also Internet radio services and popular streaming services such as Spotify, Tidal, Napster and Deezer.
Bluetooth, AirPlay 2, and built-in wi-fi for the complete networking experience
With both Bluetooth and AirPlay 2 connectivity it's easy to connect all your smartphones, tablets and compatible lap/desktops and stream music wirelessly. The AVC-S660H also comes with wi-fi and Internet radio. Simply connect to your home network via Ethernet or wi-fi and access thousands of Internet radio sites via TuneIn as well as subscription services such as Spotify Connect (requires Spotify Premium account). A Bluetooth headphone output is now also standard.
Connect it all – including a turntable
As well as six HDMI inputs, the Denon also has a wide range of other AV connectivity. Older AV sources are catered for with two composite inputs. Optical digital inputs are ideal for connecting older devices, too or upgrading the sound from a compatible CD/Network music player. Three analogue inputs are perfect for hi-fi components, such as a tuner, with the dedicated MM phono input perfect for plugging in a turntable.
