The AVR 1710S high-performance audio/video receiver pumps out 100 watts per channel to power a full seven-channel surround-sound system. It can also connect to two powered subwoofers to provide enhanced low-frequency performance for all your entertainment. While the amplifier retains the time-tested, high-current-capacity (HCC), ultrawide-bandwidth Harman Kardon design to ensure the most accurate, dynamic sound with enhanced clarity and realism – even at the highest listening levels – a digitally based power supply gives the amplifiers all the muscle they need without the weight of traditional power-supply designs and their heavy transformers. The net result is a great-sounding AVR in a small form factor that’s friendly to the environment.

The AVR 1710S can stream audio from virtually any portable device. For Apple devices, such as computers and the iPad, iPhone and iPod touch, you can stream using the receiver’s built-in AirPlay technology. (AirPlay, vTuner and Spotify Connect connections require a wired connection to a broadband network.) For other tablets, smartphones and laptops, you can take advantage of the AVR 1710S’ integrated HARMAN TrueStream Bluetooth technology. A USB port is included on the front of the AVR so you can connect devices directly without an external adapter or a wireless connection. The AVR also feature Spotify Connect, wich allow you to stream directly Music from your Spotify premium account on your phone, tablet or computer on the same network..

The HARMAN TrueStream guarantee ensures the best possible listening experience when you stream audio wirelessly via Bluetooth technology. HARMAN TrueStream tech selects the most current, most advanced wireless option to ensure the highest-quality sound, no matter what application or source device you use.

Six HDMI inputs with 3D and 30/36-bit Deep Color deliver high-definition digital video at resolutions up to 1080p with full-fidelity audio through a single cable. There is no loss of video or audio quality because of format conversion, just full-impact Hollywood excitement as its creators meant you to experience it. And with the AVR’s MHL (Mobile High-Definition Link), you can deliver high-definition audio/video content from your camera, phone, tablet or Roku Streaming Stick dongle directly to your HDTV via the AVR 1710S’ MHL connection.

Is your listening room so large that you need two subwoofers to deliver the bass that you desire? That’s not a problem with the AVR 1710S, thanks to dual subwoofer outputs that give your system a big-time boost in low-frequency clarity and realism when needed.

Control the audio in separate rooms with a single receiver. Thanks to the AVR 1710S’ assignable amplifiers, you can power the audio in a second room without adding additional components. That means you can watch sports in one room while you play the soothing sounds of classical music in another.

The AVR 1710S gives you multiple options for audio playback with its front-panel USB port. Simply connect an iPhone, iPad, iPod or USB stick to play your stored tracks through your home entertainment system. The integrated USB port also charges your iOS devices.

The AVR 171 takes the award-winning Harman Kardon look to a new level with a flush volume control and a more compact design aesthetic than earlier AVRs. Thanks to its light weight, made possible by an advanced digital power supply, the unit weighs less without sacrificing performance. It’s the perfect match for the thin glass shelves of today’s open TV/entertainment furniture.

The AVR 1710S delivers high-resolution audio that matches the digital-video quality of Blu-ray Disc™ formats, unlocking the full potential of movie soundtracks formatted with Dolby® TrueHD and DTS-HD Master Audio™ coding. No matter what mode or mood you are in, you’ll always hear audio playback at its finest.

The new HARMAN EzSet/EQ III auto-calibration process precisely adjusts the AVR 1710S’ volume levels, speaker-distance/delay-time settings and equalization to optimize audio performance automatically for your specific speaker system and room conditions. The system features an easy-to-follow menu display and includes a plug-in calibration microphone.
