TX-RZ740 – 9.2 Channel Network A/V Receiver

Code: TX-RZ740(B)

The TX-RZ740 not only elevates sound, but also that satisfied feeling you get every time you switch it on. The extra weight of the custom transformer, custom 10,000 μF capacitors, and aluminum heat-sink speak of an amp built for high-current power, enabling 3D audio to exhibit true-to-life spatiality and pin-point localization. Bass force is terrific, dynamics blindingly fast, and resolution grainless. Next-Generation Network Audio gathers multi-room platforms supported by 802.11ac*1 Wi-Fi®, or enjoy powered and unpowered audio distribution. The receiver, which supports up to 7.2.4-ch of 3D sound with external amp, is certified for IMAX® Enhanced*2 and is THX® Certified Select™ for a cinema-reference experience. From how it sounds to the way it makes you feel, the TX-RZ740 is made to savor now and in the future.
