      5. Amplifier

      Onkyo TX-NR737 Onkyo TX-NR3030

      7 channel Amplifier: Onkyo TX-NR737 features 7 channel power amplifier. It is rated at 110 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      11 channel Amplifier: Onkyo TX-NR3030 features 11 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.
      • WRAT (Wide Range Amp Technology): Onkyo TX-NR737 and Onkyo TX-NR3030 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-NR737 and Onkyo TX-NR3030 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.

      • Onkyo TX-NR737: Does not support.
      • Onkyo TX-NR3030: 9.2, 9.2.2.
      • 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.

      7. Immersive Audio Formats

      Dolby Atmos

      Onkyo TX-NR737 and Onkyo TX-NR3030 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.
