Wireless sound around your homeAll HEOS (by Denon) music systems connect together by dual-band Wi-Fi, making them easy to set up with your existing home network. Should your signal be weak in a certain part of your home, then the HEOS Extend can be used to boost the signal quality. Up to 32 HEOS units can be set up at one time, ensuring even the largest of homes are covered for multi-room music. Should you prefer to stick with a wired connection, then you can make use of the Ethernet socket that’s standard on all HEOS speaker systems.Effortless control from your smartphone or tabletOnce you’ve set up the HEOS systems, controlling them is simple with the free HEOS app. This user-friendly app uses three main tabs that feature at all times – Rooms, Music and Now Playing. Rooms allows individual control of the music being played in a particular room. You can see what music is playing where, from anywhere around your home. For an instant ‘party mode’ simply ‘pinch’ the zones together and get up to eight speaker zones, all playing the same music at once. The Music tab selects the streaming music service or stored music either on your device or a remote device connected via the DLNA network. This means you should be able to access pretty much all the digitally stored music available in your home. Now playing gives you artist, title and track timer information plus lets you control the master volume and also view the music queue.Now with BluetoothThe latest version of the HEOS 7 HS2 now comes with the added bonus of built-in Bluetooth. This means that, even if you don’t take advantage of the HEOS multi-room room system, you can get quick and easy Bluetooth streaming from any smartphone or tablet. Bluetooth connectivity is also handy if the speaker is outside of your wi-fi range – such as a sunny day in the garden.Endlessly compatibleA great benefit of choosing the HEOS system is its class-leading compatibility. In terms of music streaming services, it’s compatible with Spotify Connect (requires Spotify Premium account), Rhapsody, Pandora, TuneIn and other services offering DRM-free tracks. Supported music files include MP3, WMA, AAC, FLAC and WAV, making it compatible with just about all stored music libraries.Denon hi-fi sound qualityAs you’d expect from this range-topping HEOS, the 7 packs quite a punch when it comes to audio hardware. With two tweeters, two mid-range units plus a dedicated subwoofer, the HEOS 7 HS2 boasts an active, three-way speaker system – impressive stuff for a wireless speaker! If this wasn’t enough there are a further two passive bass radiators. In terms of sound quality, what this means is precision and accuracy of sound from the lowest to the highest notes. The five-channel Class-D, digital amplifier keeps tight control of the music ensuring hi-fi quality sound with all types of music.Added connectivity from USB, 3.5mm Aux and headphonesIn addition to wireless connectivity, the HEOS 7 HS2 also offers both USB and 3.5mm AUX connections. Plug in your USB media stick and listen to stored music anywhere on the network! The 3.5mm AUX input is ideal for adding another local source, such as MP3 player or even your TV to the main speaker zone. Unique to the HEOS 7 HS2, a headphone output is also included, making this speaker ideal as the centre of your hi-fi system.The biggest, best and undoubtedly capable of filling some pretty large rooms with sound, the HEOS 7 HS2 brings true hi-fi quality to the wireless speaker market.Specifications:Analogue RCA Inputs 3.5mmBluetooth YesDimensions WxDxH (mm) 479 x 164 x 203Dimensions WxHxD (mm) 479 x 203 x 164mmDLNA Compliant YesHeadphone Output NoInternet Radio Services YesLoudness Control via appOptical Digital Inputs NoSmartphone control YesSub Output NoTone Controls via appTuner Radio Internet radioUSB Input 1Weight (KG) 4.6Wireless Connection Wi-FiBrand HEOSColour Black & White
