With its bountiful array of connections, the TX-NR709 A/V receiver handles just about any playback device you care to hook up. Eight HDMI inputs give you plenty of scope for high-definition sources, while two HDMI outputs double your display options. HDMI supports pristine lossless audio from Dolby and DTS and video upscaling to stunning 4K resolution via Qdeo technology. Connectivity is further enhanced by a front-panel USB port for digital link-up of iPod/iPhone, and a wide range of analog and digital inputs-including S-Video and 7.1 analog multichannel inputs-for all your legacy components. The network-capable TX-NR709 also brings PC audio and internet radio to your living room, where Audyssey MultEQ XT calibrates the soundfield to match the room's unique dimensions. Onkyo's graphical OSD and navigation GUI make it easy to browse your content and adjust settings on the fly. Finally, bi-amping capability, 7.2 multichannel pre-outs, and a dedicated phono input provide further flexibility for the demanding audiophile and help propel the TX-NR709 to the head of its class. ..
