Pioneer SC-LX904's and Yamaha RX-A8A's amplifiers can be assigned for different speaker configurations.

• Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
Pioneer SC-LX904: 5.2.2, 5.2.4, 7.2.2, 7.2.4 with internal amplifier.
Yamaha RX-A8A: 5.2.2, 5.2.4, 7.2.2, 7.2.4 with internal amplifier.
• DTS:X Configurations: The following speaker configurations are supported for DTS:X:
Pioneer SC-LX904: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2, 5.2.4, 7.2.2, 7.2.4 with internal amplifier.
Yamaha RX-A8A: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2, 5.2.4, 7.2.2, 7.2.4 with internal amplifier.
• Configurations without height channels: There are also other speaker configurations available which do not include height channels:
Pioneer SC-LX904: 5.2, 7.2 with internal amplifier.
Yamaha RX-A8A: 5.2, 7.2 with internal amplifier.
• Bi-Amp: Pioneer SC-LX904 is able to bi-amp up to 4 and Yamaha RX-A8A 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.

Dolby Atmos

Pioneer SC-LX904 and Yamaha RX-A8A 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

Pioneer SC-LX904 and Yamaha RX-A8A support DTS:X.

• 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 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

Yamaha RX-A8A supports Auro-3D.

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

IMAX Enhanced

Pioneer SC-LX904 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.

Pioneer SC-LX904 comes with 7 HDMI inputs. It has 3 outputs - 1 MAIN and 1 SUB and 1 ZONE 2.

Yamaha RX-A8A comes with 7 HDMI 2.1 inputs with 8K support. It has 3 outputs - 2 for MAIN and 1 for ZONE2/4.

• 4K/60Hz Passthrough on Pioneer SC-LX904: All inputs pass up to 4K/60p (YCbCr 4:4:4) video signal.
  8K/60Hz and 4K/120Hz Passthrough on Yamaha RX-A8A: All inputs pass up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 video signal.
• 4K Upscaling on Pioneer SC-LX904: It can upscale 1080p to 4K from HDMI and analog sources.
  4K Upscaling on Yamaha RX-A8A: It can upscale up to 4K 60p 4:4:4 from HDMI and analog sources.
• Analog To HDMI Upconversion: Both receivers support 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 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-A8A only).
• 3D Ready: Both receivers are able to pass 3D video through HDMI.

HDR (High Dynamic Range)

Pioneer SC-LX904 supports HDR10, Dolby Vision and Hybrid Log-Gamma.

Yamaha RX-A8A 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)

Yamaha RX-A8A 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

Yamaha RX-A8A supports Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.
