11 channel Class D³ Amplifier

Pioneer Elite SC-LX904 features 11 channel power amplifier with Class D³ design. It is rated at 140 W (8 Ω, 1 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

Speaker Configurations

Pioneer Elite SC-LX904's 11 channel amplifier can be assigned for different speaker configurations.

• Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
5.2.2, 5.2.4, 7.2.2, 7.2.4 with internal amplifier.
• DTS:X Configurations: The speaker configurations for DTS:X are the same as for Dolby Atmos:
5.2.2, 5.2.4, 7.2.2, 7.2.4 with internal amplifier.
• Configurations without height channels: There are also other speaker configurations available which do not include height channels:
5.2, 7.2 with internal amplifier.
• 4-ch Bi-Amp: Pioneer Elite SC-LX904 allows you to bi-amp up to 4 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 Elite SC-LX904 supports 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: 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: Dolby Atmos height virtualization 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:X

Pioneer Elite SC-LX904 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: DTS Neural:X 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 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.

Sound Processing

• Advanced Sound Retriever: Compressed music enhancement in Pioneer Elite SC-LX904 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 Elite SC-LX904 comes with MCACC Pro room correction system and includes the calibration microphone.

• 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 Elite SC-LX904 features 7 HDMI inputs. It has 3 outputs: 1 MAIN and 1 SUB and 1 ZONE 2.

• 4K/60Hz Passthrough: All inputs pass up to 4K/60p (YCbCr 4:4:4) video signal.
• 4K Upscaling: Pioneer Elite SC-LX904 can upscale 1080p to 4K from HDMI and analog sources.
• Analog To HDMI Upconversion: The a/v receiver supports video upconversion, so you can connect your analog Component and Composite video sources and Pioneer Elite SC-LX904 will output them 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%.
• HDCP 2.3 Copy Protection: All inputs and outputs are HDCP 2.3 compliant which is a requirement for 4K/HDR copy-protected content transmission.
• 3D Ready: Pioneer Elite SC-LX904 is able to pass 3D video through HDMI.

HDR (High Dynamic Range)

Pioneer Elite SC-LX904 supports HDR (high dynamic range) video formats such as 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.

IMAX Enhanced

Pioneer Elite SC-LX904 is IMAX Enhanced certified. To qualify for IMAX Enhanced certification, 4K HDR televisions, projectors, sound bars, a/v receivers, loudspeakers, powered subwoofers and other premium home entertainment devices must meet carefully prescribed performance requirements established by IMAX, DTS and Hollywood's leading experts.

• What makes an IMAX Enhanced A/V receiver different from an A/V receiver with DTS:X technology? DTS:X technology is commonly found in most multi-channel A/V receivers on the market today. All IMAX Enhanced A/V receivers include DTS:X technology and deliver additional features, such as auto-sensing of IMAX Enhanced content, via IMAX Mode. IMAX Mode indicates that your A/V receiver supports fully immersive IMAX signature sound.
• IMAX Enhanced Content: IMAX Enhanced studio partners have announced IMAX Enhanced versions of movies that exclusively feature IMAX's signature picture, sound and scale.
• Picture: Stunning, ultra-vivid 4K HDR picture that utilizes the newest, proprietary Digital Media Remastering technology (DMR) developed by IMAX. DMR accurately reduces noise and grain under the filmmaker’s guidance to best optimize the content for a much higher-quality, higher-brightness display. Without this technology, high-dynamic range content can actually look worse than what was originally seen and intended by the filmmaker.
• Sound: IMAX and DTS have partnered with award-winning Hollywood sound mixers leveraging DTS:X codec technology integrated in home audio equipment and select televisions to deliver an IMAX signature sound experience with deeper bass and more dynamic range.
• Scale: Select IMAX Enhanced titles that were shot with IMAX-certified cameras or specially formatted for IMAX theatres feature its exclusive expanded aspect ratio, enabling viewers to see the full scale and scope of the picture on 4K HDR TVs.
• Streaming Services: IMAX Enhanced is now available on the world’s biggest streaming services, including Disney+, BRAVIA CORE, Tencent, iQiyi and more.

Pioneer Elite SC-LX904 offers multi-zone playback which allows you to play different input sources in 3 different rooms.

Zone 2

• Powered Zone 2: You can use the unit's 2 amplifier channels by connecting Zone 2 speakers directly to the speaker terminals. The remaining 9 channels will be left for main zone amplification.
• HDMI Output: Pioneer Elite SC-LX904 offers HDMI output for Zone 2. This means that it can send two different HDMI signals to two displays.
• Audio Pre/Line Output: If you have a dedicated amplifier for Zone 2 you can connect it to the a/v receiver via pre/line outs and use "pre out" option to control volume from the a/v receiver or use "line out" option - send fixed signal and then control volume on the Zone 2 amplifier.

Zone 3

• Powered Zone 3: You can use the unit's 2 amplifier channels by connecting Zone 3 speakers directly to the speaker terminals. The remaining 9 channels will be left for main zone amplification.
• Audio Pre/Line Output: If you have a dedicated amplifier for Zone 2 you can connect it to the a/v receiver via pre/line outs and use "pre out" option to control volume from the a/v receiver or use "line out" option - send fixed signal and then control volume on the Zone 3 amplifier.

Audio

• Analog Pre-Outs: Pioneer Elite SC-LX904 has 11.2 preamplifier outputs which allow you to connect the a/v 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 a/v receiver to power the rest.
• Analog Line Inputs: There are 6 line inputs for analog audio connection.
• Digital Inputs and Outputs: 1 optical input, 3 optical outputs and 2 coaxial inputs are available for digital audio connection.
• Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel.
