The TX-RZ620 reproduces 5.2.2-channel Dolby Atmos or DTS:X formats, with AccuReflex correcting the phase of direct and indirect sounds for cohesive audio imaging with Dolby Atmos-enabled speakers.

Any audio source can be connected to the receiver to be sent wirelessly via FireConnect, powered by Blackfire, to an optional compatible speaker placed anywhere in your home. Music selection, speaker grouping, and playback management across the home are built into the Onkyo Controller app for iOS and Android.

The Onkyo Controller app collects streaming services and network-attached audio into one smartphone app. Control playback, explore services, and distribute audio all over the home via FireConnect from one easy interface.

Selectable 5 GHz/2.4 GHz Wi-Fi helps ensure stable connectivity so you can enjoy smooth streaming over AirPlay, the Spotify app, and the local network. Bluetooth wireless technology also provides streaming from your choice of music application.

TIDAL, Deezer, Pandora, and TuneIn are onboard to help make selecting from a range of music and radio programs using the Onkyo Controller app simple.

The six rear HDMI terminals support pass-through of HDR10, HLG (Hybrid Log-Gamma), Dolby Vision, BT.2020 4K pass-through, 4K/60 Hz video playback, and HDCP 2.2 for premium video content. The HDMI I/O also supports 3D, Deep Color, x.v.Color, LipSync, DVD-Audio, SACD, multichannel PCM, and analog-to-HDMI upconversion. Further, a front HDMI terminal is convenient for video camera connection, while the rear sub HDMI out is handy for projectors.

With a 5.2-channel layout in the main media room, Powered Zone 2 speaker outputs can send amplified network, S/PDIF, and analog audio sources to a pair of stereo speakers in another room. For 5.2.2-channel home theater layouts, the pre-/line output is better suited for transmitting stereo sources available to the receiver to a hi-fi system elsewhere in the home. Multi-room playback is supported within the Onkyo Controller app.

Vector Linear Shaping Circuitry (VLSC) is designed to remove digital pulse noise for a smooth analog signal. The TX-RZ620 focuses VLSC on the front left and right channels. Data is converted between sampling points, and these points are joined with analog vectors in real time to produce a smooth output wave form. The result is a virtually noiseless, smooth, analog signal based on the digital source.

Stream any music from your smartphone, laptop, or computer to the TX-RZ620 with ease. Control playback with Chromecast-enabled apps you know from your iPhone, iPad, Android phone or tablet, Mac or Windows laptop, or Chromebook.

DTS Play-Fi is a wireless protocol designed to work with any audio app on mobile devices and computers. Flick whatever's playing to the receiver, even different sources to different components at the same time.
