• DTS:X Configurations: The following speaker configurations are supported for DTS:X:
Arcam AVR31: 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.
Denon AVC-A1H: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.4.2, 5.4.4, 5.4.6, 5.4.8, 7.4.2, 7.4.4, 7.4.6, 7.4.8, 9.4.2, 9.4.4, 9.4.6 with internal amplifier.
• Configurations without height channels: There are also other speaker configurations available which do not include height channels:
Arcam AVR31: 5.2, 7.2 with internal amplifier and 9.2 with addition of external 2 channel amplifier.
Denon AVC-A1H: 5.4, 7.4, 9.4 with internal 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 AVR31: 9.2, 9.2.2, 9.2.4, 9.2.6.
Denon AVC-A1H: 9.4, 9.4.2, 9.4.4, 9.4.6.
• Bi-Amp: Arcam AVR31 is able to bi-amp up to 2 and Denon AVC-A1H is able to bi-amp up to 7 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.

Dolby Atmos

Arcam AVR31 and Denon AVC-A1H 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 AVR31 and Denon AVC-A1H support DTS:X.

• DTS:X Pro: Denon AVC-A1H supports DTS:X Pro which is an upgraded version of DTS:X and is no longer limited with 11 channel processing.
• 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 AVR31 and Denon AVC-A1H support Auro-3D.

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

IMAX Enhanced

Arcam AVR31 and Denon AVC-A1H 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.

Arcam AVR31 and Denon AVC-A1H come with 7 HDMI 2.1 inputs with 8K support. It has 3 outputs - 2 x 8K for MAIN and 1 x 4K for ZONE2.

• 8K/60Hz and 4K/120Hz Passthrough: On both receivers all inputs pass up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 video signal.
• 8K Upscaling on Denon AVC-A1H: It can upscale up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 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.
• 3D Ready: Both receivers are able to pass 3D video through HDMI.

HDR (High Dynamic Range)

Arcam AVR31 supports HDR10, HDR10+, Dolby Vision and Hybrid Log-Gamma.

Denon AVC-A1H supports HDR10, HDR10+, Dolby Vision, Dynamic HDR 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 AVR31 and Denon AVC-A1H 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 AVR31 supports Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) Denon AVC-A1H supports Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.
