      • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
      • Arcam AVR21: This model supports DTS:X but not DTS:X Pro. Since DTS:X is limited with 11 channel processing some of the speaker configurations for Dolby Atmos are not supported here. The supported configurations are 5.2.2 with internal amplifier and 5.2.4, 7.2.2 with addition of external 2 channel amplifier and 5.2.6, 7.2.4, 9.2.2 with addition of external 4 channel amplifier.
      • Arcam AVR20: This model supports DTS:X but not DTS:X Pro. Since DTS:X is limited with 11 channel processing some of the speaker configurations for Dolby Atmos are not supported here. The supported configurations are 5.2.2 with internal amplifier and 5.2.4, 7.2.2 with addition of external 2 channel amplifier and 5.2.6, 7.2.4, 9.2.2 with addition of external 4 channel amplifier.
      • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
      • Arcam AVR21: 5.2, 7.2 with internal amplifier and 9.2 with addition of external 2 channel amplifier.
      • Arcam AVR20: 5.2, 7.2 with internal amplifier and 9.2 with addition of external 2 channel 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:

      • Arcam AVR20: 9.2, 9.2.2, 9.2.4, 9.2.6.
      • 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

      Arcam AVR21 and Arcam AVR20 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

      Arcam AVR21 and Arcam AVR20 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.

      Auro-3D

      Arcam AVR21 and Arcam AVR20 support Auro-3D.

      • Auro-Matic upmixer: Auro-Matic upmixer takes non Auro-3D sound and upmixes to the current speaker configuration.

      IMAX Enhanced

      Arcam AVR21 and Arcam AVR20 are IMAX Enhanced certified. To qualify for IMAX Enhanced certification, 4K HDR televisions, projectors, sound bars, a/v receivers, loudspeakers, powered subwoofers and other premium home entertainment devices must meet carefully prescribed performance requirements established by IMAX, DTS and Hollywood's leading experts.

      • What makes an IMAX Enhanced A/V receiver different from an A/V receiver with DTS:X technology? DTS:X technology is commonly found in most multi-channel A/V receivers on the market today. All IMAX Enhanced A/V receivers include DTS:X technology and deliver additional features, such as auto-sensing of IMAX Enhanced content, via IMAX Mode. IMAX Mode indicates that your A/V receiver supports fully immersive IMAX signature sound.

      8. HDMI

      Arcam AVR21 comes with 7 HDMI 2.1 inputs with 8K support. It has 3 outputs - 2 x 8K for MAIN and 1 x 4K for ZONE2.

      Arcam AVR20 comes with 7 HDMI inputs. It has 3 outputs - 2 for MAIN and 1 for ZONE2.

      • 8K/60Hz and 4K/120Hz Passthrough on Arcam AVR21: All inputs pass up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 video signal.
        4K/60Hz Passthrough on Arcam AVR20: All inputs pass up to 4K 50/60Hz 4:4:4 video signal.
      • 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 Copy Protection: Arcam AVR21 is HDCP 2.3 and Arcam AVR20 is HDCP 2.2 compliant which is a requirement for 4K/HDR copy-protected content transmission.
      • 3D Ready: Both receivers are able to pass 3D video through HDMI.

      HDR (High Dynamic Range)

      Arcam AVR21 supports HDR10, HDR10+, Dolby Vision and Hybrid Log-Gamma.

      Arcam AVR20 supports 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)

      Arcam AVR21 and Arcam AVR20 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

      Arcam AVR21 supports Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) for lag-free and smooth gaming.

      9. Inputs and Outputs

      Audio

      • Analog Pre-Outs: Arcam AVR21 and Arcam AVR20 have 15.2 preamplifier outputs which allow you to connect the receivers to the external power amplifiers. You may want to use a high quality external amplifier for certain channels, usually for front L/R and center, and use the receiver to power the rest. Also, both receivers have 15 channel processing but have only 7 channel amplifiers, so they need external amplifiers connected to the analog pre-outs in order to reach their maximum speaker configurations.
      • Analog Line Inputs and Outputs: There are 7 pair of line inputs on both receivers for connecting sources with analog outputs. There are also 1 pair of line outputs on the receivers.
      • Digital Inputs and Outputs: 2 optical inputs, 1 optical output and 4 coaxial inputs are available for digital audio connections on both receivers.
      • Headphone Output: There is a 3.5 mm (1/8") headphone output jack on the front panel of each receiver.
