        • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
        • Pioneer SC-LX704: 5.2.2, 5.2.4, 7.2.2 with internal amplifier and 7.2.4 with addition of external 2 channel amplifier.
        • Pioneer VSX-1023-K: Not supported.
        • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
        • Pioneer SC-LX704: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2, 5.2.4, 7.2.2 with internal amplifier and 7.2.4 with addition of external 2 channel amplifier.
        • Pioneer VSX-1023-K: Not supported.
        • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
        • Pioneer SC-LX704: 5.2, 7.2 with internal amplifier.
        • Pioneer VSX-1023-K: 5.1, 7.1 with internal amplifier.
        • Bi-Amp: Pioneer SC-LX704 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-LX704 supports Dolby Atmos.

        • Dolby Surround Upmixer: Pioneer SC-LX704 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.
        • Dolby Atmos Height Virtualization: Pioneer SC-LX704 supports 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-LX704 supports DTS:X.

        • DTS Neural:X: Pioneer SC-LX704 supports 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.

        IMAX Enhanced

        Pioneer SC-LX704 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-LX704 comes with 7 HDMI inputs. It has 3 outputs - 1 MAIN and 1 SUB and 1 ZONE 2.

        Pioneer VSX-1023-K comes with 6 HDMI inputs. It has 1 output.

        • 4K/60Hz Passthrough on Pioneer SC-LX704: All inputs pass up to 4K/60p (YCbCr 4:4:4) video signal.
          4K/30Hz Passthrough on Pioneer VSX-1023-K: All inputs pass up to 4K/30p video signal.
        • 4K Upscaling on Pioneer SC-LX704: It can upscale 1080p to 4K from HDMI and analog sources.
        • Analog To HDMI Upconversion: Pioneer SC-LX704 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 Pioneer SC-LX704 only).
        • HDCP Copy Protection: Pioneer SC-LX704 is HDCP 2.3 and Pioneer VSX-1023-K 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)

        Pioneer SC-LX704 supports HDR10, Dolby Vision and Hybrid Log-Gamma.

        Pioneer VSX-1023-K 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.

        10. Inputs and Outputs

        Audio

        • Phono Input: There is an MM phono input on Pioneer SC-LX704 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
        • Analog Pre-Outs: Pioneer SC-LX704 has 11.2 preamplifier outputs which allows you to connect the receiver to the external power amplifier. You may want to use a high quality external amplifier for certain channels, usually for front L/R and center, and use the receiver to power the rest. Also, Pioneer SC-LX704 has 11 channel processing but has only 9 channel amplifier, so it needs external amplifier connected to the analog pre-outs in order to reach its maximum speaker configuration.
        • Analog Line Inputs: There are 6 pair of line inputs on Pioneer SC-LX704 and 3 pair of line inputs on Pioneer VSX-1023-K for connecting sources with analog outputs.
        • Digital Inputs: 3 optical inputs and 2 coaxial inputs are available on Pioneer SC-LX704 and 1 optical input and 1 coaxial input are available on Pioneer VSX-1023-K for digital audio connections.
        • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
