Harman Kardon AVR 171S

This elegant receiver is the perfect combination of versatility and great sound for your music, movies, sports programs, and video games. You'll hear audio with the full clarity of Harman Kardon, loved by so many users. The receiver pumps a total of 700W into the 7-channel surround speakers (at its discretion). With a separate subwoofer to increase low-frequency performance, the bass will sound like never before. Along with support for leading audio formats (Dolby TrueHD or DTS-HD Master Audio), you will fully experience the atmosphere of movie soundtracks and sound effects. This new series is also fairly lightweight, making it suitable for glass furniture where traditional receivers will not stand.

Effective reproduction

The digital amplifier ensures the most accurate dynamic sound with clarity and realism, even at high volumes. Compared to an analogue amplifier, it does not need a traditional power supply with a heavy transformer. The result is great-sounding reproduction in smaller size and weight with greater environmental friendliness. The HARMAN GreenEdge certification guarantees that the design is environmentally friendly without compromising premium reproduction. Thanks to its advanced power supply, it delivers high-quality sound in a small, lightweight chassis where fewer metals and plastics are used.

Perfect tuning

The new HARMAN EzSet / EQ III automatic calibration adjusts sound by level to optimise sound performance for your particular speaker system and room conditions, regardless of your room layout or how you use the speakers. The result will be perfect every time. The calibration system is operated through a simple menu. The package includes a calibration microphone.

The world of modern entertainment

Whether you're launching a Blu-ray player, HD set-top box or game console, you'll want the best picture and sound quality, and also be able to handle 4K Ultra HD input signal. This receiver is a simple way to connect and enjoy them all. You can connect and play content from Apple devices such as iPad, iPhone, or iPod touch via USB connection on the front panel. With built-in Spotify Connect, you can stream music directly from your Spotify account on your phone, tablet, or computer. The built-in vTuner brings you the whole world of online radio entertainment. HARMAN TrueStream guarantees the best possible listening experience and highest quality sound when streaming audio through Bluetooth wireless technology.

Ultimate convenience

You will receive a programmable remote control for the receiver, which can also be customised to control other devices in your room. You can also control your TV, cable or satellite receiver, and other sources for playback. Do you want to control your home cinema experience from the comfort of your own mobile device? Simply download the Harman Kardon Remote application.
