The AVR-1713 allows you to enjoy not only the dynamic surround sound of the latest 3D videos in a 5.1-channel home theater but a variety of advanced network capabilities as well. These functions let you listen to thousands of free Internet radio stations or play music files stored on a shared hard disk (NAS) or PC. Since the AVR-1713 also supports AirPlay®, you can listen to music content from the iTunes® library on your iPad®, iPhone®, iPod®, iPod touch®, or PC/Mac via the network. In addition, if you download the new Denon Remote App to your iPad, iPhone, iPod touch, or Android smartphone, you can use the device to operate the main controls of the AVR- 1713. With the addition of an external amplifier, the AVR-1713 supports multi-zone operation, allowing two different sources to be enjoyed in separate rooms at the same time. New "Setup Assistant" prompts you through initial setup and makes it a breeze.
