      6. Amplifier

      Onkyo TX-NR5100 Onkyo TX-NR6100

      7 channel Amplifier: Onkyo TX-NR5100 features 7 channel power amplifier. It is rated at 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      7 channel Amplifier: Onkyo TX-NR6100 features 7 channel power amplifier. It is rated at 100 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      • Dynamic Audio Amplification: Onkyo TX-NR5100 and Onkyo TX-NR6100 feature 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-NR6100 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.

      7. Speaker Configurations

      Onkyo TX-NR5100's and Onkyo TX-NR6100's amplifiers can be assigned for different speaker configurations.

      • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
      • Onkyo TX-NR5100: 5.2.2 with internal amplifier.
      • Onkyo TX-NR6100: 5.2.2 with internal amplifier.
      • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
      • Onkyo TX-NR5100: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.
      • Onkyo TX-NR6100: 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-NR5100: 5.2, 7.2 with internal amplifier.
      • Onkyo TX-NR6100: 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-NR5100 and Onkyo TX-NR6100 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.
      • Dolby Atmos Height Virtualization: Both models support Dolby Atmos Height Virtualization which is a digital signal processing solution that leverages Dolby's deep understanding of human audio perception to create the sensation of overhead sound from the listener-level speakers.

      DTS:X

      Onkyo TX-NR5100 and Onkyo TX-NR6100 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 Virtual:X: Both models feature DTS Virtual:X which bridges the gap between DTS:X codec and the reality of so many consumers' homes, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. If you have a limited speaker setup you will miss a full immersive potential of your entertainment system. DTS Virtual:X adds height and surround audio effect to your system without adding height speakers. It works with multiple configurations and delivers immersive sound experience out of 5.1 or even 2.1 speaker layouts.
      • DTS Dialog Control: Both models have 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 2.1

      Onkyo TX-NR5100 comes with 4 HDMI 2.1 inputs with 8K support. It has 2 outputs which work parallelly and output the same signal.

      Onkyo TX-NR6100 comes with 3 HDMI 2.1 inputs with 8K support and 3 inputs with 4K support. It has 2 outputs - 1 Main and 1 Sub/Zone2.

      • 8K/60Hz and 4K/120Hz Passthrough on Onkyo TX-NR5100: All inputs pass up to 8K/60p (RGB/YCbCr4:4:4) video signal.
        8K/60Hz and 4K/120Hz Passthrough on Onkyo TX-NR6100: 3 out of 6 inputs pass up to 8K/60p (RGB/YCbCr4:4:4) and the rest of the inputs pass up to 4K 50/60Hz 4:4:4 video signal.
      • 4K Upscaling: Both receivers can upscale 1080p to 4K from HDMI sources.
      • 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 both models).
      • HDCP 2.3 Copy Protection: Both receivers are HDCP 2.3 compliant which is a requirement for 4K/HDR copy-protected content transmission.
      • Quick Media Switching (QMS): With HDMI 2.1a, Quick Media Switching for movies and video uses the HDMI VRR mechanism to eliminate the blackout period when an HDMI Source device switches its video mode. As long as the resolution remains the same and only the frame rate changes, QMS will instantly switch between frame rates. QMS eliminates A/V blackouts by using VRR technology to change frame rates, allowing instant changes from 24Hz to 60Hz frame rate, and anywhere in-between. The viewer never sees blank screens and gets a seamless experience (available on both models).
      • 3D Ready: Both receivers are able to pass 3D video through HDMI.

      HDR (High Dynamic Range)

      Both receivers support HDR10, HDR10+, Dolby Vision and Hybrid Log-Gamma. 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.


      Enhanced Audio Return Channel (eARC)

      Onkyo TX-NR5100 and Onkyo TX-NR6100 support Audio Return Channel (ARC) which allows the compatible TV to send audio signal to the a/v receiver through the same HDMI cable which is used to send audio and video signals to the TV. So one HDMI cable is used to transfer audio signal in both directions. New Enhanced ARC will support uncompressed audio formats such as Dolby Atmos, DTS:X, Dolby TrueHD and DTS HD Master Audio whereas the previous ARC could support only Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.


      Gaming Features

      Both receivers support Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.
