Shifting Home Theater Performance and Control into Another Gear

To move to a level beyond purely functional home theater, the TX-SR674 gives you everything you need for audibly powerful, visually expressive home entertainment.

And with HDTV in mind, the TX-SR674 also offers High-Definition Multimedia Interface (HDMI) and connectivity with the latest high-definition disc formats. Capping it off with Audyssey 2EQ™ room acoustics correction technology, the TX-SR674 stands out as one of the more complete A/V receivers in its class.
