Onkyo TX-SR383's and Sony STR-ZA2000ES's amplifiers can be assigned for different speaker configurations.

• Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
Onkyo TX-SR383: 5.2.2 with internal amplifier.
Sony STR-ZA2000ES: Not supported.
• DTS:X Configurations: The following speaker configurations are supported for DTS:X:
Onkyo TX-SR383: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.
Sony STR-ZA2000ES: Not supported.
• Configurations without height channels: There are also other speaker configurations available which do not include height channels:
Onkyo TX-SR383: 5.2, 7.2 with internal amplifier.
Sony STR-ZA2000ES: 5.2, 7.2 with internal amplifier.
• Bi-Amp: Sony STR-ZA2000ES 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.

Dolby Atmos

Onkyo TX-SR383 supports Dolby Atmos.

• Dolby Surround Upmixer: Onkyo TX-SR383 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

Onkyo TX-SR383 supports DTS:X.

• DTS Neural:X: Onkyo TX-SR383 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.
