TX-NR809 - 7.2ch., 180W, 110dB, 16Ohms
<b>7.2-Channel Network A/V Receiver</b>
Listen Up If You’re Serious About Home Entertainment
With its advanced processing and fabulous array of connections, the TX-NR809 is ready to lift the roof off. Eight HDMI® inputs handle all your high-def content, from master-quality audio to upscaled 4K video. Home network capability lets you bring streaming internet radio and PC audio to your living room. And the drop-down front panel conceals a plethora of one-touch audio controls and A/V inputs. Video—whether standard or high definition—gets the royal treatment from a high-quality HQV® Vida™ processor and independent ISF calibration for each source. Advanced audio options include bi-amping, 7.2 multichannel pre-outs, and distributed multi-zone audio. As you’d expect from a receiver near the top of Onkyo’s mid-range line-up, construction is first-rate. A massive transformer, symmetrical L/R channels, separate power and pre-amp blocks, and a highly rigid chassis provide the bedrock for a superlative audio performance. Built with the serious home cinema fan in mind, the TX-NR809 offers a class-leading mix of power, features, and performance.
