Big sound to match big 4k screens, the TX-RZ710 is THX Certified for Theater Reference Sound. Its premium RZ build quality boasts non-phase-shift amps, huge capacitors, and high-output transformer to pull every drop of emotion from object-based soundtracks, which are precisely phase-aligned with new AccuReflex calibration technology. Music blooms with vibrant energy thanks to high-current amplification, whether it's a stream from Spotify via Google Cast, Hi-res audio from home media servers, or classic vinyl from your turntable. FireConnect streams any of these sources from the receiver to a wireless speaker in another room, while Zone 2 HDMI sends 4k video to a second TV. Gathering your media and giving easy access across the home, the TX-RZ710 will make nightly entertainment an event to look forward to.
