Denon AVR-S640H's and Integra DRX-8.4's amplifiers can be assigned for different speaker configurations.

• Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
Denon AVR-S640H: Not supported.
Integra DRX-8.4: 5.4.2, 5.4.4, 7.4.2, 7.4.4 with internal amplifier.
• DTS:X Configurations: The following speaker configurations are supported for DTS:X:
Denon AVR-S640H: Not supported.
Integra DRX-8.4: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.4.2, 5.4.4, 7.4.2, 7.4.4 with internal amplifier.
• Configurations without height channels: There are also other speaker configurations available which do not include height channels:
Denon AVR-S640H: 5.2 with internal amplifier.
Integra DRX-8.4: 5.4, 7.4 with internal amplifier.
• Bi-Amp: Integra DRX-8.4 is able to bi-amp up to 3 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

Integra DRX-8.4 supports Dolby Atmos.

• Dolby Surround Upmixer: Integra DRX-8.4 supports 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: Integra DRX-8.4 supports 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

Integra DRX-8.4 supports DTS:X.

• DTS Neural:X: Integra DRX-8.4 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: Integra DRX-8.4 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.

Auro-3D

Integra DRX-8.4 supports Auro-3D.

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

IMAX Enhanced

Integra DRX-8.4 is 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.

Denon AVR-S640H comes with 5 HDMI inputs. It has 1 output.

Integra DRX-8.4 comes with 6 HDMI 2.1 inputs with 8K support and 1 inputs with 4K support. It has 3 outputs - 1 MAIN and 1 SUB and 1 ZONE 2.

• 4K/60Hz Passthrough on Denon AVR-S640H: All inputs pass up to 4K 50/60Hz 4:4:4 video signal.
  8K/60Hz and 4K/120Hz Passthrough on Integra DRX-8.4: 6 out of 7 inputs pass up to 8K 48/50/60Hz RGB/YCbCr 4:4:4 12-bit and 4K 100/120Hz RGB/YCbCr 4:4:4 12-bit and the rest of the inputs pass up to 4K 50/60Hz 4:4:4 video signal.
• 8K Upscaling on Integra DRX-8.4: It can upscale from 1080p and 4K up to 8K 50/60Hz and 4K 50/60Hz from HDMI and analog sources.
• Analog To HDMI Upconversion: Integra DRX-8.4 supports analog to HDMI Upconversion, so you can input your analog video sources and output them digitally via HDMI. This means that you will need only one HDMI cable to connect to your TV.
• 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: Denon AVR-S640H is HDCP 2.2 and Integra DRX-8.4 is 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 Integra DRX-8.4 only).
• 3D Ready: Both receivers are able to pass 3D video through HDMI.

HDR (High Dynamic Range)

Denon AVR-S640H supports HDR10, Dolby Vision and Hybrid Log-Gamma.

Integra DRX-8.4 supports 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)

Integra DRX-8.4 supports 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

Denon AVR-S640H supports Auto Low Latency Mode (ALLM) Integra DRX-8.4 supports Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.
