      6. Amplifier

      Onkyo TX-RZ920 Sony STR-ZA2000ES

      9 channel Amplifier: Onkyo TX-RZ920 features 9 channel power amplifier. It is rated at 135 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      7 channel Amplifier: Sony STR-ZA2000ES features 7 channel power amplifier. It is rated at 75 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).

      • Dynamic Audio Amplification: Onkyo TX-RZ920 features 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-RZ920 is THX™ Select™ (previously known as Select2) certified. This means that it is for medium sized rooms, up to 2,000 cubic feet in size, with a 10-12 foot viewing distance from the screen.

      • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
      • Onkyo TX-RZ920: 5.2.2, 5.2.4, 7.2.2 with internal amplifier and 7.2.4 with addition of external 2 channel amplifier.
      • Sony STR-ZA2000ES: Not supported.
      • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
      • Onkyo TX-RZ920: 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.
      • Sony STR-ZA2000ES: Not supported.
      • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
      • Onkyo TX-RZ920: 5.2, 7.2 with internal amplifier.
      • Sony STR-ZA2000ES: 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.

      8. Immersive Audio Formats

      Dolby Atmos

      Onkyo TX-RZ920 supports Dolby Atmos.

      • Dolby Surround Upmixer: Onkyo TX-RZ920 supports 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.

      DTS:X

      Onkyo TX-RZ920 supports DTS:X.

      • DTS Neural:X: Onkyo TX-RZ920 supports 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: Onkyo TX-RZ920 supports 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.

      9. HDMI

      Onkyo TX-RZ920 comes with 8 HDMI inputs. It has 2 outputs - 1 Main and 1 Sub/Zone2.

      Sony STR-ZA2000ES comes with 6 HDMI inputs. It has 2 outputs - 1 Main and 1 Sub/Zone2.

      • 4K/60Hz Passthrough: On both receivers all inputs pass up to 4K/60p (RGB/YCbCr4:4:4) video signal.
      • 4K Upscaling on Onkyo TX-RZ920: It can upscale 1080p to 4K from HDMI and analog sources.
        4K Upscaling on Sony STR-ZA2000ES: It can upscale up to 4K/60p from HDMI sources.
      • Analog To HDMI Upconversion: Onkyo TX-RZ920 supports 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 Onkyo TX-RZ920 only).
      • HDCP 2.2 Copy Protection: Both receivers are HDCP 2.2 compliant which is a requirement for 4K/HDR copy-protected content transmission.
      • 3D Ready: Both receivers are able to pass 3D video through HDMI.

      HDR (High Dynamic Range)

      Onkyo TX-RZ920 supports HDR10, Dolby Vision and Hybrid Log-Gamma.

      Sony STR-ZA2000ES does not support HDR. 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-RZ920 supports 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.

      10. Inputs and Outputs

      Audio

      • Phono Input: There is an MM phono input on Onkyo TX-RZ920 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
      • Analog Pre-Outs: Onkyo TX-RZ920 has 11.2 preamplifier outputs which allows you to connect the 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 receiver to power the rest. Also, Onkyo TX-RZ920 has 11 channel processing but has only 9 channel amplifier, so it needs external amplifier connected to the analog pre-outs in order to reach its maximum speaker configuration.
      • Analog Line Inputs: There are 6 pair of line inputs on Onkyo TX-RZ920 and 4 pair of line inputs on Sony STR-ZA2000ES for connecting sources with analog outputs.
      • Digital Inputs: 2 optical inputs and 2 coaxial inputs are available on Onkyo TX-RZ920 and 2 optical inputs and 1 coaxial input are available on Sony STR-ZA2000ES for digital audio connections.
