        • Pioneer SC-LX904: 5.2.2, 5.2.4, 7.2.2, 7.2.4 with internal amplifier.
        • Pioneer VSX-934: 5.2.2 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.
        • Pioneer VSX-934: 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:
        • Pioneer SC-LX904: 5.2, 7.2 with internal amplifier.
        • Pioneer VSX-934: 5.2, 7.2 with internal amplifier.
        • Bi-Amp: Pioneer SC-LX904 is able to bi-amp up to 4 and Pioneer VSX-934 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

        Pioneer SC-LX904 and Pioneer VSX-934 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 Pioneer VSX-934 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 Virtual:X: Pioneer SC-LX904 supports DTS Virtual:X which bridges the gap between DTS:X codec and the reality of so many consumers' homes, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. If you have a limited speaker setup you will miss a full immersive potential of your entertainment system. DTS Virtual:X adds height and surround audio effect to your system without adding height speakers. It works with multiple configurations and delivers immersive sound experience out of 5.1 or even 2.1 speaker layouts.
        • 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.

        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.

        9. HDMI

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

        Pioneer VSX-934 comes with 6 HDMI inputs. It has 2 outputs - 1 MAIN and 1 SUB/ZONE 2.

        • 4K/60Hz Passthrough: On both receivers all inputs pass up to 4K/60p (YCbCr 4:4:4) video signal.
        • 4K Upscaling: Both receivers can upscale 1080p to 4K from HDMI sources. Pioneer SC-LX904 can also upscale from analog sources.
        • Analog To HDMI Upconversion: Pioneer SC-LX904 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: Pioneer SC-LX904 is HDCP 2.3 and Pioneer VSX-934 is 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)

        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.
