        7. Speaker Configurations

        Denon AVR-S660H's and Yamaha RX-V4A's amplifiers can be assigned for different speaker configurations.

        • Configurations: Available configurations are:
        • Denon AVR-S660H: 5.2 with internal amplifier.
        • Yamaha RX-V4A: 5.2 with internal amplifier.
        • Bi-Amp: Yamaha RX-V4A 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.

        8. HDMI 2.1

        Denon AVR-S660H comes with 3 HDMI 2.1 inputs with 8K support and 3 inputs with 4K support. It has 1 output.

        Yamaha RX-V4A comes with 4 HDMI 2.1 inputs with 8K support. It has 1 output.

        • 8K/60Hz and 4K/120Hz Passthrough on Denon AVR-S660H: 3 out of 6 inputs pass up to 8K 50/60Hz (YCbCr 4:2:0/8-bit) and 4K 100/120Hz (RGB/YCbCr 4:4:4/8, 10-bit and YCbCr 4:2:2/12-bit) and the rest of the inputs pass up to 4K 50/60Hz 4:4:4 video signal.
          8K/60Hz and 4K/120Hz Passthrough on Yamaha RX-V4A: All inputs pass up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 video signal.
        • 8K Upscaling on Denon AVR-S660H: It can upscale from 1080p and 4K up to 8K 50/60Hz and 4K 50/60Hz from HDMI sources.
          4K Upscaling on Yamaha RX-V4A: It can upscale up to 4K 60p 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.
        • 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 Yamaha RX-V4A only).
        • 3D Ready: Both receivers are able to pass 3D video through HDMI.

        HDR (High Dynamic Range)

        Denon AVR-S660H supports HDR10, HDR10+, Dolby Vision, Dynamic HDR and Hybrid Log-Gamma.

        Yamaha RX-V4A 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)

        Denon AVR-S660H and Yamaha RX-V4A 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.
