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 so you can enjoy older DVDs and games in high resolution. Music lovers can choose from a selection of internet music services and stream almost any 192/24 hi-res, lossless, or compressed file format (including 5.6 MHz DSD) from compatible network- attached devices using built-in Wi-Fi and our free remote app. Bluetooth is also standard. Combining these features with class-leading sound quality and an easy-to-use GUI, the TX-NR737 delivers powerful studio-master entertainment at an affordable price.

WRAT (Wide Range Amplifier Technology) is based on high-current, low-impedance architecture. High instantaneous current realizes ultimate control of the speaker drivers for accurate and musical audio reproduction, from the most delicate piano passages the thunderous roar of an orchestra in full flight. High current better handles impedance fluctuations from the speakers (which can dramatically increase the load on the receiver), and with 125 Watts/Ch (6ohms 1kHz, 2 Channels Driven, FTC) there is always enough power to respond instantly to dynamic gains in movie soundtracks and music.

To achieve best-in-class current delivery, the TX-NR737 is built around a custom high-output transformer, extra-large customized capacitors, and low impedance copper bus-plates. Three-Stage Inverted Darlington Circuitry amplifiers feature a discrete low-impedance output stage with high-current transistors for instantaneous power and extremely low distortion. Unlike some A/V receivers, the audio and video processors, DAC section, networking, pre-amp, amplifiers, and power supply are all separated to minimize electrical interference (noise) on audio signals. The culmination of over 60 years€ audio engineering experience, WRAT preserves the life and character of the master recording while guaranteeing an emotionally moving experience whether you€re listening to compressed digital music, a treasured LP, or a hi-res movie soundtrack.
