High-performance audio/video receiver that boasts multiple wireless connectivity options, six HDMI inputs and 700 watts of beautiful sound. Power, performance and more connectivity options than you’ll ever need: Introducing the Harman Kardon® networked AVR 171S, the answer to any entertainment enthusiast’s hunger for performance and versatility. It’s got muscle: up to 700 watts (100 watts per channel). Its 7.2-channel A/V receiver is equipped with HARMAN TrueStream Bluetooth® connectivity, Apple AirPlay, vTuner™ Internet radio and Spotify Connect, giving you multiple options for streaming audio. And with six 3D-ready HDMI® 2.0 inputs, including one equipped for MHL to connect mobile devices, and two HDMI outputs, you’ll have more than enough ways to connect to everything you love – movies, HDTV, sports, MHL-equipped devices and the Roku Streaming Stick™ dongle. While the AVR 171’s connectivity alone makes it desirable, its sound really strikes a chord. It’s the first Harman Kardon AVR to feature our exclusive Natural Sound Processing (NSP), which creates a rich, enveloping surround-sound from any source – particularly with two-channel streaming content. And its EzSet/EQ™ III system automatically calibrates the AVR to your speakers and listening environment. The AVR 171S is light, too, thanks to HARMAN GreenEdge™ certification – delivering all the power you need with low environmental impact. For those who want it all, the AVR 171S can’t be matched.

AVR 171S is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Feeling good after one week use Used for last one week and feeling good. Connected to HKTS 16BQ along with another two front speakers and sounds good. OSD & remote need to be improvised and they need to compete with other brands by adding more features. Installation of stand was a lil tough.

Is it possible to use the AVR171S as a 5.1 system - with only the front speakers, center speaker, surround speakers and one sub woofer?

Asked by: Angelo
Yes, you can choose to not use all channels on the AVR 171S. It's possible to disable the channels you won't use, and if at any point in the future you would decide to add the extra surround speakers, you can simply enable the channels again.

Hi everyone. I have a harman kardon AVR 171S . This product support 4K 30 fps but not support 4K 60 fps. Why ?

Asked by: glioa
Hi Glioa, Thank you for your question. The product supports 4K pass-through and with HDCP 1.4 encryption. If you want to watch 4K BlueRays then our product will not work on that format. The reason it is 30 fps is due to product design. If you need more information, please contact us at customer.support@harman.com

What is the best way to connect the AVR171S to the SB 35 sound bar?

Asked by: Shmulik
Hi. Actually these two devices are not made to function together, and there is no logical way of connecting them. If you want to discuss the possibilities in detail, please contact Harman Helpdesk in Europe, or contact the distributor of our brands in Israel.

Hi, I have this AVR 171S and I have been trying to find the latest software version to download. I'm unable to find any software for this model on - https://www.harmankardon.com/software.html Thanks, Hadi

Asked by: Hadi
Hi Hadi, The website you are trying to find your AVR on only has software for US models of our products. The AVR171S is manufactured for your region ( which also includes EU and Asia ). For these regions, there is no download available through our website, and you will need to contact our Customer Support department to send you the correct files. I would like to add to this, that if your AVR171S works as intended, a firmware update, just to have the latest version, is not needed, this will not add features. If your AVR171S is not performing how it should, I would suggest you contact the seller of your AVR171S for technical assistance. Of course, you are always welcome to contact us on customer.support@harman.com
