        7. Speaker Configurations

        Pioneer SC-LX502's and Pioneer VSX-831's amplifiers can be assigned for different speaker configurations.

        • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
        • Pioneer SC-LX502: 5.2.2 with internal amplifier.
        • Pioneer VSX-831: Not supported.
        • DTS:X Configurations: The following speaker configurations are supported for DTS:X:
        • Pioneer SC-LX502: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.
        • Pioneer VSX-831: Not supported.
        • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
        • Pioneer SC-LX502: 5.2, 7.2 with internal amplifier.
        • Pioneer VSX-831: 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 SC-LX502 supports Dolby Atmos.

        • Dolby Surround Upmixer: Pioneer SC-LX502 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

        Pioneer SC-LX502 supports DTS:X.

        • DTS Neural:X: Pioneer SC-LX502 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.
