7. Speaker Configurations

Denon AVR-X550BT's and Yamaha RX-V685's amplifiers can be assigned for different speaker configurations.

Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:

Denon AVR-X550BT: Not supported.

Yamaha RX-V685: 5.2.2 with internal amplifier.

DTS:X Configurations: The following speaker configurations are supported for DTS:X:

Denon AVR-X550BT: Not supported.

Yamaha RX-V685: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.

Configurations without height channels: There are also other speaker configurations available which do not include height channels:

Denon AVR-X550BT: 5.2 with internal amplifier.

Yamaha RX-V685: 5.2, 7.2 with internal amplifier.

Bi-Amp: Yamaha RX-V685 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. Immersive Audio Formats

Dolby Atmos

Yamaha RX-V685 supports Dolby Atmos.

Dolby Surround Upmixer: Yamaha RX-V685 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.

DTS:X

Yamaha RX-V685 supports DTS:X.

DTS Neural:X: Yamaha RX-V685 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: Yamaha RX-V685 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.

9. HDMI

Denon AVR-X550BT comes with 5 HDMI inputs. It has 1 output.

Yamaha RX-V685 comes with 5 HDMI inputs. It has 2 outputs which work parallelly and output the same signal.

4K/60Hz Passthrough: On both receivers all inputs pass up to 4K 50/60Hz 4:4:4 video signal.
4K Upscaling on Yamaha RX-V685: It can upscale up to 4K 60p 4:4:4 from HDMI and analog sources.
Analog To HDMI Upconversion: Yamaha RX-V685 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-X550BT is HDCP 2.2 and Yamaha RX-V685 is 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)

Both receivers support 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)

Yamaha RX-V685 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.
