7 channel Amplifier: Sony STR-DH790 features 7 channel power amplifier. It is rated at 90 W (6 Ω, 20 Hz - 20 kHz, 2 channel driven).
Onkyo TX-SR393's and Sony STR-DH790's amplifiers can be assigned for different speaker configurations.
- Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
- Onkyo TX-SR393: 3.1.2 with internal amplifier.
- Sony STR-DH790: 5.2.2 with internal amplifier.
- DTS:X Configurations: The following speaker configurations are supported for DTS:X:
- Onkyo TX-SR393: The speaker configurations for DTS:X are the same as for Dolby Atmos - 3.1.2 with internal amplifier.
- Sony STR-DH790: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.
- Configurations without height channels: There are also other speaker configurations available which do not include height channels:
- Onkyo TX-SR393: 5.2 with internal amplifier.
- Sony STR-DH790: 5.2, 7.2 with internal amplifier.
- Bi-Amp: Sony STR-DH790 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 Surround Upmixer: Both models support 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: Onkyo TX-SR393 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 Neural:X: Both models feature 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 Virtual:X: Onkyo TX-SR393 supports DTS Virtual:X which bridges the gap between DTS:X codec and the reality of so many consumers' homes, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. If you have a limited speaker setup you will miss a full immersive potential of your entertainment system. DTS Virtual:X adds height and surround audio effect to your system without adding height speakers. It works with multiple configurations and delivers immersive sound experience out of 5.1 or even 2.1 speaker layouts.
- DTS Dialog Control: Onkyo TX-SR393 supports 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.
- Compressed Music Enhancer: Onkyo TX-SR393 features Compressed Music Enhancer which enhances the quality of the music files with lossy compression.
- Advanced Music Optimizer: Compressed music enhancement in Onkyo TX-SR393 is done by Onkyo’s Advanced Music Optimizer. While MP3 or AAC files may sound fine through the headphones of your portable digital player, the limitations of these files can be exposed when played back through a quality home entertainment system. This is because a significant amount of high-frequency bit information is lost during the file-compression process. To counter this, Onkyo has designed the Advanced Music Optimizer to compensate for lost bit information and improve the quality of compressed audio signals. This results in a clearer and more expansive sound. Also included in this technology is a loudness correction feature that further improves the audio character of compressed files.
- AccuEQ: First, AccuEQ detects the presence of speakers and evaluates the impedance of each. Next, it pinpoints their distance relative to the main listening position using the mic and sets suitable sound-pressure levels. Then it selects the optimal crossover frequency so that deeper bass rolls smoothly off to the subwoofer. Finally, AccuEQ performs frequency response equalization based on room-acoustic and speaker data collected via microphone. The sound-field is now tailored around the listening position, resulting in a more immersive and realistic in-film experience.
Onkyo TX-SR393 and Sony STR-DH790 support Dolby Atmos. It is a cinematic audio format in which sounds exist as individual entities, called audio objects. In Dolby Atmos, any sound can exist as an independent audio object, free of channel restrictions. They can be precisely placed and moved anywhere in your room, including overhead, to flow above and around you in three-dimensional space. Through the use of audio objects, overhead sound, and all the richness, clarity, and power of Dolby sound, Dolby Atmos turns your room into an amazing place for entertainment. The format supports up to 128 simultaneous independent audio objects in a mix for rich, realistic, and breathtaking sound. It recreates the director's original concept through descriptive metadata to provide customized playback for home theater and delivers sounds above you through overhead speakers, special upward-firing Dolby Atmos speakers, or a Dolby Atmos enabled sound bar.
Onkyo TX-SR393 and Sony STR-DH790 support DTS:X. A technique used in DTS:X is similar to the one used in Dolby Atmos. Instead of a fixed number of channels, DTS:X defines object locations from the listener in polar coordinates. An a/v receiver then dynamically renders sound according to the current speaker configuration. The speaker layout employed by DTS:X is the sum of Dolby Atmos and Auro-3D. It has standard 7.1 channel base layer, a 5 channel height layer above the base layer on the front and side walls, and 3 rows of speakers on the ceiling.
Enhanced Audio Return Channel (eARC)
Sony STR-DH790 supports Audio Return Channel (ARC) feature 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.
Onkyo TX-SR393 comes with AccuEQ and Sony STR-DH790 comes with Advanced D.C.A.C. room correction system.
Onkyo TX-SR393 and Sony STR-DH790 come with 4 HDMI inputs. It has 1 output.
- 4K/60Hz Passthrough: On both receivers all inputs pass up to 4K/60p (RGB/YCbCr4:4:4) video signal.
- 4K Upscaling on Onkyo TX-SR393: It can upscale 1080p to 4K from HDMI sources.
- 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 both models).
- HDCP 2.2 Copy Protection: Both receivers are 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)
Both receivers support HDR10, Dolby Vision and Hybrid Log-Gamma.
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.
- HDR10: HDR10 uses the wide-gamut Rec. 2020 color space. It sends static metadata via video stream to the TV which calibrates its screen brightness and color according to that. HDR10 supports 10-bit color which corresponds to 1024 shades of the primary RGB colors. It is technically limited to a maximum of 10,000 nits peak brightness, however common HDR10 contents are mastered with peak brightness from 1,000 to 4,000 nits.
- Dolby Vision: Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. It covers content creation, distribution, and playback. Like HDR10+, it includes dynamic metadata that are used to adjust and optimize each frame of the HDR video to the consumer display's capabilities in a way specified by the content creator. Dolby Vision allows for a maximum resolution of 8K up to 12-bit color depth, maximum peak brightness of 10,000 nits and a color gamut up to Rec. 2020. It uses Dolby's proprietary dynamic metadata defined in SMPTE ST 2094-10.
- Hybrid Log-Gamma (HLG): The Hybrid Log-Gamma (HLG) is a transfer function developed mainly for HDR live video feed and over-the-air broadcasts. It is an HDR format that uses BT.2020 color primaries and a bitdepth of 10-bit. It is backward compatible with the transfer function of SDR and is designed to be better-suited for television broadcasting, where the metadata required for other HDR formats is not backward compatible with non-HDR displays. HLG defines a non-linear optical-electro transfer function, in which the lower half of the signal values use a gamma curve and the upper half of the signal values use a logarithmic curve.
