      6. Amplifier

      Onkyo TX-NR636 Pioneer SC-75

      7 channel Amplifier: Onkyo TX-NR636 features 7 channel power amplifier. It is rated at 95 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      9 channel Class D3 Amplifier: Pioneer SC-75 features 9 channel power amplifier with Class D3 design. It is rated at 135 W (8 Ω, 1 kHz, 2 channel driven) and is able to drive 4 ohm speakers.
      • WRAT (Wide Range Amp Technology): Onkyo TX-NR636 features 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

      Pioneer SC-75 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-NR636's and Pioneer SC-75's amplifiers can be assigned for different speaker configurations.

      • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
      • Onkyo TX-NR636: 5.2.2 with internal amplifier.
      • Pioneer SC-75: Not supported.
      • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
      • Onkyo TX-NR636: 5.2, 7.2 with internal amplifier.
      • Pioneer SC-75: 5.2, 7.2, 9.2 with internal amplifier.
      • Front Wide Channel support: With the presence of two front wide speakers you can enhance the front surround stage. The following speaker configurations are available for front wide channels:
      • Onkyo TX-NR636: Does not support.
      • Pioneer SC-75: 9.2.
      • 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-NR636 supports Dolby Atmos.

      • Dolby Surround Upmixer: Onkyo TX-NR636 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.
