      6. Amplifier

      Onkyo TX-RZ800 Onkyo TX-NR838

      7 channel Amplifier: Onkyo TX-RZ800 features 7 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: Onkyo TX-NR838 features 7 channel power amplifier. It is rated at 130 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      • WRAT (Wide Range Amp Technology): Onkyo TX-RZ800 and Onkyo TX-NR838 feature Onkyo’s Wide Range Amp Technology (WRAT) circuit layout that prevents phase shifting by pushing the roll-off point higher than the listening-level frequency. Amplifying sound without phase shift creates an uncommonly well-focused and realistic audio image. If phase shift occurs and signal timing is not accurate, then neither is the resulting audio image.

      THX™ Select™2 Plus certification

      Onkyo TX-RZ800 and Onkyo TX-NR838 are THX™ Select™2 Plus certified. This means that they are ideally suited for a room where the screen-to-seat viewing distance is approximately 3 to 4 meters, and the room size is approximately 56 cubic meters.

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-RZ800 and Onkyo TX-NR838 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.

      DTS:X

      Onkyo TX-RZ800 supports DTS:X.

      • DTS Neural:X: Onkyo TX-RZ800 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-RZ800 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-RZ800 comes with 8 HDMI inputs. It has 2 outputs - 1 Main and 1 Sub/Zone2.

      Onkyo TX-NR838 comes with 7 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/YCbCr4:2:2, 24 bit) video signal.
      • 4K Upscaling on Onkyo TX-NR838: It can upscale up to 4K/30p (Marvell Qdeo) 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 Onkyo TX-RZ800 only).
      • HDCP 2.2 Copy Protection: Both receivers are HDCP 2.2 compliant which is a requirement for 4K/HDR copy-protected content transmission.
