View larger THX Theater-Reference sound meets Ultra HD entertainment Step up to THX-certified surround sound with the TX-NR737—the most potent and future-ready A/V receiver in its class. With a high- current massive transformer, discrete Three-Stage Inverted Darlington Circuitry amplification, and extremely robust construction, this heavyweight serves up floorshaking theater-reference sound. There are 4K/60 Hz-capable HDMI inputs for Ultra HD gaming and video at 60 fps, as well as support for HDCP 2.2. As most Hollywood movie studios are adopting HDCP 2.2 copy protection for future Full HD and 4K releases (including content streamed via the internet), this is a highly desirable feature. Also included is QdeoTM 4K upscaling technology
