      6. Amplifier

      Onkyo TX-NR509 Onkyo TX-NR575

      5 channel Amplifier: Onkyo TX-NR509 features 5 channel power amplifier. It is rated at 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).

      7 channel Linear Class A/B Amplifier: Onkyo TX-NR575 features 7 channel power amplifier with Linear Class A/B design. It is rated at 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.
      • Dynamic Audio Amplification: Onkyo TX-NR575 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.

      • Onkyo TX-NR509: Not supported.
      • Onkyo TX-NR575: 5.2.2 with internal amplifier.
      • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
      • Onkyo TX-NR509: Not supported.
      • Onkyo TX-NR575: 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-NR509: 5.1 with internal amplifier.
      • Onkyo TX-NR575: 5.2, 7.2 with internal amplifier.
      • Bi-Amp: Onkyo TX-NR575 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-NR575 supports Dolby Atmos.

      • Dolby Surround Upmixer: Onkyo TX-NR575 supports Dolby Surround Upmixer.

The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.

      DTS:X

      Onkyo TX-NR575 supports DTS:X.

      • DTS Neural:X: Onkyo TX-NR575 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-NR575 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.
