Denon AVR2113 7.1 Channel AV Receiver in Black Fully discrete identical quality & power for all 7 channels (125 W x 7ch) To faithfully reproduce the original surround sound each of the AVR-2113’s 7 channels is equipped with the same power amp of equal power. Since these power amps also use discrete circuits configured with parts strictly selected for their contribution to high sound quality rather than with low-cost integrated circuits (ICs) the surround sound playback is of impeccably high quality. The “simple & straight” design concept has been thoroughly implemented in the signal paths to contribute to immaculately clean audio playback. Signal paths are as short as possible to keep signal degradation in the audio circuitry to an absolute minimum. Network Air Play & Denon Remote App When connected to a network the AVR-2113 can play audio files & still images such as photographs that are stored on your computer. You can also listen to internet radio & a host of other online music sources that use network technology. The AVR-2113 also supports Air Play that lets you stream your music library from an iPhone iPad iPod touch or i Tunes. The Denon Remote App available for free on i Tunes or Google Plus App store transfers your smartphone or tablet in a nice remote control supporting the key features of the AVR. But it doesn’t stop here as you can control the network audio streaming from your PC & internet radio function supported by cover art. That’s ease of use that’s fun. Easy operation with Setup Assistant & Advanced Graphical User Interface (GUI ) The new Setup Assistant in 7 languages incl. English French & German will guide you through the full setup of the unit including speaker wiring Audyssey speaker calibration source selection & network setup all supported by graphics showing what to do & where to find the right connector. The GUI will let you keep the full overview even while watching a movie. Just check your settings or get the volume & surround mode indication overlayed on the film you watch. Don’t miss any scene. Multiroom / Multisource The AVR-2113 lets you enjoy a program source in the Main Zone (the room where the AVR-2113 is located) & in Zone 2 (another room). The source can be the same for both zones or you can enjoy different sources in those zones if you prefer. You just need to assign 2 of the 7 built in amplifiers for the second room.
