      6. Amplifier

      Onkyo TX-SR343 Onkyo TX-RZ900

      5 channel Amplifier: Onkyo TX-SR343 features 5 channel power amplifier. It is rated at 65 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).

      7 channel Amplifier: Onkyo TX-RZ900 features 7 channel power amplifier. It is rated at 140 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-SR343 and Onkyo TX-RZ900 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.
      • Toroidal Transformer: Onkyo TX-RZ900 has a toroidal transformer which in general costs several times more than a regular C-core transformer and radiates less electromagnetic noise outside its donut shaped core.

      THX™ Select™2 Plus certification

      Onkyo TX-RZ900 is THX™ Select™2 Plus certified. This means that it is 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.

      7. Speaker Configurations

      Onkyo TX-SR343's and Onkyo TX-RZ900's amplifiers can be assigned for different speaker configurations.

      • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
      • Onkyo TX-SR343: Not supported.
      • Onkyo TX-RZ900: 5.2.2 with internal amplifier.
      • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
      • Onkyo TX-SR343: Not supported.
      • Onkyo TX-RZ900: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.
      • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
      • Onkyo TX-SR343: 5.1 with internal amplifier.
      • Onkyo TX-RZ900: 5.2, 7.2 with internal amplifier.
      • Bi-Amp: Onkyo TX-RZ900 is 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-RZ900 supports Dolby Atmos.

      • Dolby Surround Upmixer: Onkyo TX-RZ900 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-RZ900 supports DTS:X.

      • DTS Neural:X: Onkyo TX-RZ900 features 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-RZ900 has 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-SR343 comes with 4 HDMI inputs. It has 1 output.

      Onkyo TX-RZ900 comes with 8 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.
      • 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-RZ900 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-SR343 does not support HDR.

      Onkyo TX-RZ900 supports HDR10 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.
