The Denon AVR-2312 A / V receiver Features 7.2 channel audio. The sound for each speaker is amplified by identical circuits consisting of separate components so that your signal is preserved as much as possible. Bi-amping is also an option and the AVR-2312 has a second audio zone so you can listen to your music in another room. The 7 HDMI 1.4 inputs ensure that you can easily connect all your devices and even your standard definition material can be seen in full HD thanks to the up-scaler. You control your Denon AVR-2312 in addition to the remote control, including via the Denon remote app for the iPhone and iPod. You can also control the AVR-2312 via your browser if it is connected to your home network. You also play your music and photos over the network and listen to internet radio.
