      6. Amplifier

      Onkyo TX-NR686 Pioneer SC-LX501

      7 channel Linear Class A/B Amplifier: Onkyo TX-NR686 features 7 channel power amplifier with Linear Class A/B design. It is rated at 100 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      7 channel Class D3 (Direct Energy HD) Amplifier: Pioneer SC-LX501 features 7 channel power amplifier with Class D3 design (Direct Energy HD). It is rated at 120 W (8 Ω, 1 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      • Dynamic Audio Amplification: Onkyo TX-NR686 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.

      THX™ Select™ (previously known as Select2) certification

      Onkyo TX-NR686 is THX™ Select™ (previously known as Select2) certified. This means that it is for medium sized rooms, up to 2,000 cubic feet in size, with a 10-12 foot viewing distance from the screen.

      Onkyo TX-NR686's and Pioneer SC-LX501's amplifiers can be assigned for different speaker configurations.

      • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
      • Onkyo TX-NR686: 5.2.2 with internal amplifier.
      • Pioneer SC-LX501: 5.2.2 with internal amplifier.
      • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
      • Onkyo TX-NR686: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.
      • Pioneer SC-LX501: 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-NR686: 5.2, 7.2 with internal amplifier.
      • Pioneer SC-LX501: 5.2, 7.2 with internal amplifier.
      • 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-NR686 and Pioneer SC-LX501 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-NR686 and Pioneer SC-LX501 support DTS:X.

      • DTS Neural:X: Both models feature 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-NR686 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.
