Great entertainment deserves a great presentation.

Blu-ray™ or DVD discs, HDTV, MP3s, video games – the Harman Kardon® AVR 270 audio/video receiver delivers their content to you in 7.1-channel surround sound (at 100 watts per channel) and superb video. This receiver has all the inputs you need to handle just about any electronic entertainment – including HDMI® video. If you want your music from the “cloud,” it has built-in AirPlay and DLNA® 1.5 certified Ethernet connectivity. It’s easy to handle, too, thanks to its intuitive, high-definition menu system, programmable remote control, mobile app and EzSet/EQ™ calibration to simplify setup and operation. The AVR 270 is technology that serves virtually all of your entertainment needs.

Harman Kardon engineers have built the AVR 270 audio/video receiver for a premium home theater experience. No room is too big for the receiver’s high-current, 100-watt-per-channel amplifier. And speaking of the channels: With 7.1 of them, the AVR 270 empowers you to add an extra dimension to the traditional five-channel surround-sound setup, or go with 5.1 channels in a main viewing room and use the extra two channels to power the sound in another room.
The AVR 270 receiver can simultaneously play two different sound sources in two different zones. When you choose to connect your main system to 5.1 channels, you can use its other two sound channels as an independent system in a second room.
Hear your networked media sources as never before in pitch-perfect surround sound. DLNA 1.5 enables the AVR 270 to stream audio from compatible devices on your home network, allowing you to enjoy them with a level of quality that you would not have thought possible.
This free, downloadable software enables your AVR 270 to enjoy DLNA compatibility with your Mac OS devices or older Windows®-based computers. And it helps organize and clean up the cover art on your music files, regardless of your computer type.
Hear how truly amazing your streaming music can sound. AirPlay allows you to stream music wirelessly from your iOS® devices and from the iTunes service through your AVR 270 for superb audio.
The Harman Kardon EzSet/EQ system automatically sets key system parameters and fine-tunes the AVR 270’s sound to your specific listening room with the press of a few buttons.
Your AVR 270 doesn’t need a docking station. Instead, its front-panel USB port allows an easy-access connection point for any iOS devices. It even lets you access music stored on a flash drive. Furthermore, the included AVR remote gives you a convenient way to control any connected device.
Enjoy many of your favorite radio stations, podcasts and Internet-only programming from around the globe in outstanding surround sound on your AVR 270. vTuner® Internet radio gives you quick, easy access to your favorite online stations.
A free, downloadable app allows you to transform your smartphone or tablet into an easy-to-use remote control. Compatible with most iOS and Android™ devices, this high-definition graphical user interface gives you full control of your AVR 270 and all its connected media through the convenience of your favorite portable device.
3D content plays as vividly and realistically in your home as it would in a movie theater, thanks to the AVR 270’s advanced HDMI connectivity. Experience everything from a 3D TV to a 3D Blu-ray Disc™ recording with astonishing realism.
