Our take on the Onkyo TX-RZ720 THX-Certified 7.2-Channel 4K Network A/V Receiver
The Onkyo TX-RZ720 is a 7.2-channel network AV receiver with THX Select2 Plus certification and 4K/HDR passthrough. It delivers about 110 watts per channel (two channels driven) and supports Dolby Atmos and DTS:X for object-based surround. Its AccuEQ room calibration, powered Zone 2 output and built-in streaming (Chromecast built-in, AirPlay, Spotify, Tidal) make it a flexible hub for a mid-size home theater. It suits buyers who want strong amplification and Atmos without stepping up to Onkyo's higher RZ models, though it lacks the RZ820's extra HDMI output and higher power.

Questions and answers
- Does it support Dolby Atmos and DTS:X?
- Yes. It processes 7.2-channel Dolby Atmos and DTS:X, so you can run height or overhead speakers in a 5.2.2 or 7.2 layout.
- How much power does it deliver?
- About 110 watts per channel into 8 ohms with two channels driven, and roughly 180 watts into 6 ohms. That is enough for most bookshelf and floorstanding speakers in a medium room.
- Can I run a second zone?
- Yes. Zone 2 is powered, so a second pair of speakers can play a different source without an extra amplifier.
- Does it pass 4K and HDR?
- It passes 4K/60Hz with HDR10 and Dolby Vision, but it has no HDMI 2.1 features like 8K or variable refresh rate.
- Does it have a phono input?
- Yes, there is a moving-magnet phono input for a turntable, plus a built-in phono equalizer.
- How does it compare with the TX-RZ820?
- The RZ820 adds more power, a second HDMI output and a stronger chassis. The RZ720 keeps the same Atmos and streaming features for smaller rooms.
