        7. Speaker Configurations

        Pioneer VSX-LX505's and Pioneer VSX-45's amplifiers can be assigned for different speaker configurations.

        • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
        • Pioneer VSX-LX505: 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-45: Not supported.
        • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
        • Pioneer VSX-LX505: 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-45: Not supported.
        • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
        • Pioneer VSX-LX505: 5.2, 7.2 with internal amplifier.
        • Pioneer VSX-45: 5.2 with internal amplifier.
        • 2-ch Bi-Amp: Both models are 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 VSX-LX505 supports Dolby Atmos.

        • Dolby Surround Upmixer: Pioneer VSX-LX505 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 VSX-LX505 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 VSX-LX505 supports DTS:X.

        • DTS Neural:X: Pioneer VSX-LX505 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 VSX-LX505 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 VSX-LX505 comes with 6 HDMI 2.1 inputs with 8K support and 1 inputs with 4K support. It has 2 outputs - 1 MAIN and 1 SUB/ZONE 2.

        Pioneer VSX-45 comes with 6 HDMI inputs. It has 1 output.

        • 8K/60Hz and 4K/120Hz Passthrough on Pioneer VSX-LX505: 6 out of 7 inputs pass up to 8K/60p RGB/YCbCr4:2:0/10-bit uncompressed or RGB/YCbCr4:4:4/12-bit compressed (TV needs DSC) and the rest of the inputs pass up to 4K 50/60Hz 4:4:4 video signal.
          4K/60Hz Passthrough on Pioneer VSX-45: All inputs pass up to 4K/60p (4:4:4 24-bit)
          4K/60p (4:2:2 36-bit)
          4K/24p (4:4:4 36-bit) video signal.
        • 8K Upscaling on Pioneer VSX-LX505: It can upscale 1080p to 4K/8K and 4K to 8K from HDMI and analog sources.
          4K Upscaling on Pioneer VSX-45: It can upscale up to 4K/60p (Marvell Qdeo) 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 Pioneer VSX-LX505 only).
        • HDCP Copy Protection: Pioneer VSX-LX505 is HDCP 2.3 and Pioneer VSX-45 is HDCP 2.2 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 Pioneer VSX-LX505 only).
        • 3D Ready: Both receivers are able to pass 3D video through HDMI.

        HDR (High Dynamic Range)

        Pioneer VSX-LX505 supports HDR10, HDR10+, Dolby Vision and Hybrid Log-Gamma.

        Pioneer VSX-45 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.


        Enhanced Audio Return Channel (eARC)

        Pioneer VSX-LX505 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

        Pioneer VSX-LX505 supports Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR) and Quick Frame Transport (QFT) for lag-free and smooth gaming.

        10. Inputs and Outputs

        Audio

        • Phono Input: There is an MM phono input on Pioneer VSX-LX505 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
        • Analog Pre-Outs: Pioneer VSX-LX505 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 VSX-LX505 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 4 pair of line inputs on Pioneer VSX-LX505 and 2 pair of line inputs on Pioneer VSX-45 for connecting sources with analog outputs.
        • Digital Inputs: 1 optical input and 1 coaxial input are available for digital audio connections on both receivers.
        • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
