        Pioneer SC-81's and Pioneer SC-91's amplifiers can be assigned for different speaker configurations.

        • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
        • Pioneer SC-81: Not supported.
        • Pioneer SC-91: 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-81: 5.2, 7.2 with internal amplifier.
        • Pioneer SC-91: 5.2, 7.2 with internal amplifier.
        • Front Wide Channel support: With the presence of two front wide speakers you can enhance the front surround stage. The following speaker configurations are available for front wide channels:
        • Pioneer SC-81: 7.2.
        • Pioneer SC-91: 7.2.
        • 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-91 supports Dolby Atmos.

        • Dolby Surround Upmixer: Pioneer SC-91 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.

        10. Inputs and Outputs

        Audio

        • Analog Pre-Outs: Pioneer SC-81 has 2.2 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, both receivers have 7 channel processing but have only 7 channel amplifiers, so they need external amplifiers connected to the analog pre-outs in order to reach their maximum speaker configurations.
        • Analog Line Inputs and Outputs: There are 3 pair of line inputs on both receivers for connecting sources with analog outputs. There are also 1 pair of line outputs on the receivers.
        • Digital Inputs: 2 optical inputs and 2 coaxial inputs are available on Pioneer SC-81 and 1 optical input and 1 coaxial input are available on Pioneer SC-91 for digital audio connections.
        • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
