Bi-amp Capability

Denon AVR-S640H's and Sony STR-ZA3000ES's amplifiers can be assigned for different speaker configurations.

• Configurations: Available configurations are:
Denon AVR-S640H: 5.2 with internal amplifier.
Sony STR-ZA3000ES: 5.2, 7.2 with internal amplifier.
• Bi-Amp: Sony STR-ZA3000ES is 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.

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

Sony STR-ZA3000ES comes with 6 HDMI inputs. It has 2 outputs - 1 Main and 1 Sub/Zone2.

• 4K/60Hz Passthrough: On both receivers all inputs pass up to 4K 50/60Hz 4:4:4 video signal.
• 4K Upscaling on Sony STR-ZA3000ES: It can upscale up to 4K/60p 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 Denon AVR-S640H only).
• HDCP 2.2 Copy Protection: Both receivers are 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)

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

Sony STR-ZA3000ES does not support HDR. 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.

Gaming Features

Denon AVR-S640H supports Auto Low Latency Mode (ALLM) for lag-free and smooth gaming.
