Onkyo TX-RZ50

We already listed pros and cons of each model. However, you may also find useful to look at their common strengths and weaknesses shown side-by-side.

• Dynamic Audio Amplification: Onkyo TX-RZ70 and Onkyo TX-RZ50 feature Dynamic Audio Amplification which is Onkyo’s amplification philosophy that focuses on capturing the energy and dynamism contained in the audio signal and reproducing it without loss. Audio signals are not static like a test tone, but rather a countless collection of constantly moving waves. While static measurements such as S/N ratio and Total Harmonic Distortion are important, Onkyo believes that excellent dynamic and transient response is the key to emotionally involving sound. Dynamism - the “life” in music - is achieved when the amp can respond to changes in the signal instantaneously, so notes start and stop naturally and the nuances in attack, decay, sustain, and release are voiced with conviction. Onkyo home theater receivers represent the culmination of almost 70 years’ experience in amplifier design. The unique elements of their amplification system comprise high-current, low-impedance architecture to accurately control large speaker cones while enabling instantaneous response to dynamic changes, and discrete wide-range amplifier circuit topology to eliminate phase shift for clear and accurate audio imaging.

THX™ Select™ (previously known as Select2) certification

Onkyo TX-RZ70 and Onkyo TX-RZ50 are THX™ Select™ (previously known as Select2) certified. This means that they are made for medium sized rooms, up to 2,000 cubic feet in size, with a 10-12 foot viewing distance from the screen.

Onkyo TX-RZ70's and Onkyo TX-RZ50's amplifiers can be assigned for different speaker configurations.

• Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
Onkyo TX-RZ70: 5.2.2, 5.2.4, 7.2.2, 7.2.4 with internal amplifier.
Onkyo TX-RZ50: 5.2.2, 5.2.4, 7.2.2 with internal amplifier and 7.2.4 with addition of external 2 channel amplifier.
• DTS:X Configurations: The following speaker configurations are supported for DTS:X:
Onkyo TX-RZ70: 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.
Onkyo TX-RZ50: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2, 5.2.4, 7.2.2 with internal amplifier and 7.2.4 with addition of external 2 channel amplifier.
• Configurations without height channels: There are also other speaker configurations available which do not include height channels:
Onkyo TX-RZ70: 5.2, 7.2 with internal amplifier.
Onkyo TX-RZ50: 5.2, 7.2 with internal amplifier.
• 2-ch Bi-Amp: Both models are able 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 and Onkyo TX-RZ50 support Dolby Atmos.

• Dolby Surround Upmixer: Both models support Dolby 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.
• Dolby Atmos Height Virtualization: Both models support Dolby Atmos Height Virtualization which 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 and Onkyo TX-RZ50 support DTS:X.

• DTS Neural:X: Both models feature DTS Neural:X which 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: Both models have 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 and Onkyo TX-RZ50 are 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 comes with 7 HDMI 2.1 inputs with 8K support. It has 3 outputs - 1 Main and 1 Sub and 1 Zone2.

Onkyo TX-RZ50 comes with 7 HDMI 2.1 inputs with 8K support. It has 2 outputs - 1 Main and 1 Sub/Zone2.

• 8K/60Hz and 4K/120Hz Passthrough: On both receivers all inputs pass up to 8K/60p (RGB/YCbCr4:4:4) video signal.
• 8K Upscaling: Both receivers can upscale 1080p to 4K/8K and 4K to 8K from HDMI and analog sources.
• Analog To HDMI Upconversion: Both receivers support analog to HDMI Upconversion, so you can input your analog video sources and output them digitally 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% (available on both models).
• HDCP 2.3 Copy Protection: Both receivers 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 (available on both models).
• 3D Ready: Both receivers are able to pass 3D video through HDMI.

HDR (High Dynamic Range)

Both receivers support HDR10, HDR10+, Dolby Vision and Hybrid Log-Gamma. 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)

Onkyo TX-RZ70 and Onkyo TX-RZ50 support Audio Return Channel (ARC) which 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

Both receivers support Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.
