Integrated Green Edge technology
The Harman Kardon AVR 3700 utilizes new integrated GreenEdge technology, which uses ultra lightweight digital amplifiers to create powerful and precise amplification. The AVR 3700 uses a custom designed digital power supply that delivers the amplifier power and superior sound you expect from Harman Kardon without the need for hefty transformers. The result is the same power as conventional designs with a lower overall carbon footprint impact. The GreenEdge technology provides dramatic energy savings without compromising premium performance using digital power supply to improve efficiency without compromising on Harman Kardon legendary sound performance. A smaller, lightweight design also results in a lower carbon footprint.
7.2-channel sound at 125 watts per channel
Harman Kardon engineers have built the AVR 3700 audio/video receiver for a premium home theater experience. No room is too big for this receiver, thanks to its high-current capability and 125 watts per channel. And speaking of the receiver's channels: With 7.2 of them, the AVR 3700 empowers you to add a vertical dimension to the traditional five-channel surround-sound setup, with two front-height channels. The ".2" in "7.2" means that you can easily add a second subwoofer for ultimate bass in large listening rooms.
Multizone functionality with Zone II remote
The AVR 3700 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 the receiver's other two sound channels as an independent system in a second room. An included Zone II IR (infrared) remote control ensures that the people in the second zone can make their own choices without ever having to leave the zone.
Built-in Wi-Fi networking capability
The AVR 3700 lets you listen to almost any sound file stored on your home network. Access computer files wirelessly. Combine Wi-Fi audio with AirPlay; you'll make your iPhone, iPod touch or iPad sound better than you ever thought possible - and you won't have to connect any additional cords or use an Ethernet cable.
DLNA 1.5 certified connectivity
Hear your networked media sources as never before in pitch-perfect surround sound. DLNA 1.5 enables the AVR 3700 to stream audio and video from the devices on your home network using the receiver's built-in Wi-Fi technology or an Ethernet connection, which allow you to enjoy audio and video at a quality that you would not have thought possible.
