Onkyo TX-RZ70

Onkyo TX-RZ70 was introduced in 2023 and represents a current flagship model of a manufacturer. It is equipped with 11 channel amplifier with 140 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) power per channel and is capable of 11.2 maximum channel processing. It supports Dolby Atmos and DTS:X, passes 8K/60Hz and 4K/120Hz and upscales 1080p to 4K/8K and 4K to 8K video signal.

We evaluated the a/v receiver and gave 94 overall score out of 100. Our ranking system is based on the amplifier specifications, audio and video features, connectivity, multizone capabilities, radio and many other details.

For more details about the ranking please go to    Evaluation section.

In this section we present pros and cons of Onkyo TX-RZ70.

Onkyo TX-RZ70's 11 channel amplifier can be assigned for different speaker configurations.

• Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
5.2.2, 5.2.4, 7.2.2, 7.2.4 with internal amplifier.
• DTS:X Configurations: The speaker configurations for DTS:X are the same as for Dolby Atmos:
5.2.2, 5.2.4, 7.2.2, 7.2.4 with internal amplifier.
• Configurations without height channels: There are also other speaker configurations available which do not include height channels:
5.2, 7.2 with internal amplifier.
• 2-ch Bi-Amp: Onkyo TX-RZ70 allows you to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.

Dolby Atmos

Onkyo TX-RZ70 supports Dolby Atmos with Surround Upmixer and Atmos Height Virtualization.

• Surround Upmixer: If the content is not mixed in Dolby Atmos then the Dolby surround upmixer will expand the audio to all channels including ceiling speakers. The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.
• Atmos Height Virtualization is a digital signal processing solution that leverages Dolby's deep understanding of human audio perception to create the sensation of overhead sound from the listener-level speakers.

DTS:X

Onkyo TX-RZ70 supports DTS:X with Neural:X.

• Neural:X is an advanced upmixer that can take non DTS:X content and upmix it to the DTS:X speaker layout. It has replaced the DTS Neo family with improved flexibility.
• DTS Dialog Control: This function adjusts the dialog levels during playback of the DTS:X stream. It allows you to separately increase the dialog levels in contrast with the background sound and hear dialog easily even under noisy circumstances.

IMAX Enhanced

Onkyo TX-RZ70 is IMAX Enhanced certified. To qualify for IMAX Enhanced certification, 4K HDR televisions, projectors, sound bars, a/v receivers, loudspeakers, powered subwoofers and other premium home entertainment devices must meet carefully prescribed performance requirements established by IMAX, DTS and Hollywood's leading experts.

• What makes an IMAX Enhanced A/V receiver different from an A/V receiver with DTS:X technology? DTS:X technology is commonly found in most multi-channel A/V receivers on the market today. All IMAX Enhanced A/V receivers include DTS:X technology and deliver additional features, such as auto-sensing of IMAX Enhanced content, via IMAX Mode. IMAX Mode indicates that your A/V receiver supports fully immersive IMAX signature sound.

Onkyo TX-RZ70 features 7 HDMI 2.1 inputs with 8K support. It has 3 outputs: 1 Main and 1 Sub and 1 Zone2.

• 8K/60Hz and 4K/120Hz Passthrough: All inputs pass up to 8K/60p (RGB/YCbCr4:4:4) video signal.
• 8K Upscaling: Onkyo TX-RZ70 can upscale 1080p to 4K/8K and 4K to 8K from HDMI and analog sources.
• Analog To HDMI Upconversion: The a/v receiver supports video upconversion, so you can connect your analog Component and Composite video sources and Onkyo TX-RZ70 will output them via HDMI. This means that you will need only one HDMI cable to connect to your TV.
• BT.2020 Color Space: BT.2020 or Rec. 2020 is a color standard which delivers a wider color gamut compared to Rec. 709. It covers approximately 75% of the total visual spectrum while the Rec. 709 covers only 35%.
• HDCP 2.3 Copy Protection: All inputs and outputs are HDCP 2.3 compliant which is a requirement for 4K/HDR copy-protected content transmission.
• Quick Media Switching (QMS): With HDMI 2.1a, Quick Media Switching for movies and video uses the HDMI VRR mechanism to eliminate the blackout period when an HDMI Source device switches its video mode. As long as the resolution remains the same and only the frame rate changes, QMS will instantly switch between frame rates. QMS eliminates A/V blackouts by using VRR technology to change frame rates, allowing instant changes from 24Hz to 60Hz frame rate, and anywhere in-between. The viewer never sees blank screens and gets a seamless experience.
• 3D Ready: Onkyo TX-RZ70 is able to pass 3D video through HDMI.

HDR (High Dynamic Range)

Onkyo TX-RZ70 supports HDR (high dynamic range) video formats such as HDR10, HDR10+, Dolby Vision and Hybrid Log-Gamma via HDMI ports. High dynamic range video has greater dynamic range than standard dynamic range (SDR) video with brighter whites and deeper blacks. The result is greater contrast and more details in dark and bright areas, better color and depth.

Enhanced Audio Return Channel (eARC)

Audio Return Channel (ARC) feature allows the compatible TV to send audio signal to the a/v receiver through the same HDMI cable which is used to send audio and video signals to the TV. So one HDMI cable is used to transfer audio signal in both directions. New Enhanced ARC will support uncompressed audio formats such as Dolby Atmos, DTS:X, Dolby TrueHD and DTS HD Master Audio whereas the previous ARC could support only Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.

Gaming Features

Onkyo TX-RZ70 supports Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.

Dirac Live delivers a larger sweet spot, accurate staging, clarity, voice intelligibility, and a deeper, tighter bass not otherwise possible. Fully tunable to your preference.

Onkyo TX-RZ70 offers multi-zone playback which allows you to play different input sources in 3 different rooms.

Zone 2

• Powered Zone 2: You can use the unit's 2 amplifier channels by connecting Zone 2 speakers directly to the speaker terminals. The remaining 9 channels will be left for main zone amplification.
• HDMI Output: Onkyo TX-RZ70 offers HDMI output for Zone 2. This means that it can send two different HDMI signals to two displays.
• Audio Pre/Line Output: If you have a dedicated amplifier for Zone 2 you can connect it to the a/v receiver via pre/line outs and use "pre out" option to control volume from the a/v receiver or use "line out" option - send fixed signal and then control volume on the Zone 2 amplifier.

Zone 3

• Powered Zone 3: You can use the unit's 2 amplifier channels by connecting Zone 3 speakers directly to the speaker terminals. The remaining 9 channels will be left for main zone amplification.
• Audio Pre/Line Output: If you have a dedicated amplifier for Zone 2 you can connect it to the a/v receiver via pre/line outs and use "pre out" option to control volume from the a/v receiver or use "line out" option - send fixed signal and then control volume on the Zone 3 amplifier.

Audio

• Phono Input: There is an MM phono input with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the a/v receiver.
• Analog Pre-Outs: Onkyo TX-RZ70 has 11.2 preamplifier outputs which allow you to connect the a/v receiver to the external power amplifier. You may want to use a high quality external amplifier for certain channels, usually for front L/R and center, and use the a/v receiver to power the rest.
• Analog Line Inputs: There are 4 line inputs for analog audio connection.
• Digital Inputs: 2 optical inputs and 2 coaxial inputs are available for digital audio connection.
• Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel.

Video

• HDMI:
Inputs: 7 (1 front)   Outputs: 3 (1 Main, 1 Sub, 1 Zone2)
8K Inputs: 7
• Composite Video: Connect you VCR, Laserdisc player and other old video equipment with composite video cables.
Inputs: 2   Outputs: 0
• Component Video: Component video connection gives you the higher quality video compared to the composite video connection. So in case your old DVD player and other equipment do not have an HDMI output but have Component video output use this connection over the composite one. Onkyo TX-RZ70 supports up to 480i/576i resolution on Component video connectors.
