Amplifier

Speaker Configurations

Pioneer SC-LX501'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-LX501: 5.2.2 with internal amplifier.
Pioneer SC-91: 5.2.2 with internal amplifier.
• DTS:X Configurations: The following speaker configurations are supported for DTS:X:
Pioneer SC-LX501: The speaker configurations for DTS:X are the same as for Dolby Atmos - 5.2.2 with internal amplifier.
Pioneer SC-91: Not supported.
• Configurations without height channels: There are also other speaker configurations available which do not include height channels:
Pioneer SC-LX501: 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-LX501: Does not support.
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.



Dolby Atmos

Pioneer SC-LX501 and Pioneer SC-91 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.

• 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.

DTS:X

Pioneer SC-LX501 supports 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.

• DTS Neural:X: Pioneer SC-LX501 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.

Sound Processing

• Compressed Music Enhancer: Pioneer SC-LX501 and Pioneer SC-91 feature Compressed Music Enhancer which enhances the quality of the music files with lossy compression.
Advanced Sound Retriever: Compressed music enhancement in Pioneer SC-LX501 and Pioneer SC-91 is done by Pioneer’s Advanced Sound Retriever. Hear the detail, warmth and clarity, the way the artist intended it, from all of your highly compressed MP3 and WMA files stored on USB, Smartphone and portable media players. By restoring data that tend to get lost in the digital compression process, Pioneers Advanced Sound Retriever Technology enhances audio reproduction all the way upto 20 Khz frequencies.

Room Calibration

Pioneer SC-LX501 comes with MCACC and Pioneer SC-91 comes with MCACC Pro room correction system.

• MCACC: Pioneer’s exclusive Multi-Channel Acoustic Calibration System (MCACC) delivers an easy-to-use, automatic sound adjustment system to precision-tune your Pioneer and Pioneer Elite receivers with minimal effort. Every MCACC system comes with a microphone to measure and analyze reverb characteristics. The equalizer optimally adjusts sound parameters to fit the size and shape of your home environment while maintaining the integrity of high-resolution playback without any degradation to the quality of your music.

HDMI

Pioneer SC-LX501 comes with 7 HDMI inputs. It has 2 outputs - 1 MAIN and 1 SUB/ZONE 2.

Pioneer SC-91 comes with 7 HDMI inputs. It has 2 outputs - 1 for MAIN and 1 for MAIN/HDZONE.

• 4K/60Hz Passthrough: On both receivers all inputs pass up to 4K/60p (YCbCr 4:4:4) video signal.
• 4K Upscaling: Both receivers can upscale up to 4K/60p (YCbCr 4:4:4) from HDMI sources. Pioneer SC-91 can also upscale from analog sources.
• Analog To HDMI Upconversion: Pioneer SC-91 supports 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 SC-LX501 only).
• HDCP 2.2.0 Copy Protection: Both receivers are HDCP 2.2.0 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)

Pioneer SC-LX501 supports HDR10 and Dolby Vision.

Pioneer SC-91 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.

• 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.
