Achieves simultaneous high power output of 11ch and 880W. AV amplifier "SC-LX904" that plays the highest peak sound in the history of Pioneer

"To faithfully reproduce the feelings contained in the work"

This is our belief in the sound of our Pioneer AV amplifiers.

To achieve this, Pioneer's flagship AV amplifier has continued to be equipped with our original "Direct Energy HD Amplifier" and has been working on the evolution of sound from the previous model each time a new product is developed.

In 2019, we developed the "SC-LX904" equipped with a revolutionary sound quality improvement function along with a major improvement of the "Direct Energy HD Amplifier".

This "SC-LX904" is equipped with various technologies such as MCACC and PQLS that have been refined from the Dolby Digital processor SP-D07 announced in 1995, and is tuned by a skilled audio engineer by making full use of new sound quality improvement technology. We have achieved sound quality that is truly the highest peak of Pioneer AV amplifiers.

We would like Japanese customers to experience the "Pioneer's highest peak AV amplifier in history" SC-LX904, which surpasses the sound of all models released in the past, and this time we will challenge crowdfunding.

Equipped with the highest sound quality and functions in Pioneer history.

Further evolution of "Direct Energy HD Amplifier" that realizes multi-channel simultaneous high power output

The original "Direct Energy HD Amplifier", which has a good reputation for high speaker drive power and sound quality, has been further evolved and equipped to realize simultaneous high power output of 11ch (880W).

The SC-LX904 "Direct Energy HD Amplifier" has renewed the power coil, which is the heart of the product, and realized a more ideal speaker drive.

The film capacitor used in the rectifying section of the power supply and the filter section of the Direct Energy HD amplifier was newly jointly developed with Shinyei Capacitor.

Brings more expressive and stable bass reproduction.

Considering noise, we adopted a board that shields and separates the Class-D amplifier and AUDIO section.

The balance signal from the pre-stage is shielded and a high-quality signal is transmitted to the amplifier stage, further evolving the features of the Class-D amplifier.

Furthermore, by balancing the audio signal from the preamplifier section to the power amplifier section, we have realized richer and higher quality deep bass reproduction of the "Direct Energy HD Amplifier" that suppresses noise.

All speaker outputs support impedances of 4Ω to 16Ω, and can be connected to various speakers without any special settings or switching.

By adopting all channels of this high-performance DAC and combining it with a direct energy HD amplifier that realizes multi-channel simultaneous high-power output, it is possible to play and adjust with the same quality from any channel, and the philosophy of Pioneer AV receiver "multi-channel stereo". We have realized "Phonic Philosophy".

Equipped with "MCACC Pro", an automatic sound field correction technology that makes the listening room an ideal playback environment with the attached microphone.

"MCACC" is a function that has been installed in Pioneer AV amplifiers that automatically adjusts all speakers to sound at the same distance at the same distance based on the measurement results of the playback environment using the attached microphone.

In addition to the basic functions of "MCACC", "MCACC Pro" has "Auto Phase Control Plus" that corrects the delay of LFE in the content, "Standing wave control" that eliminates the deterioration of sound quality due to the influence of the room, and More accurate sound field correction by adding "background noise measurement" that cancels the operating noise of the air conditioner at the time of measurement, and "full band phase control" that eliminates the group delay that occurs between speaker units and between speakers. to hold.

It also accurately corrects the distance of speakers installed on the ceiling, which is very useful for 3D surround playback of Dolby Atmos, DTS: X, and IMAX Enhanced.

Supports "IMAX Enhanced" that reproduces the power and immersiveness of the IMAX theater at home

New support for sound playback of "IMAX Enhanced" that reproduces the popular "IMAX" in movie theaters in home theaters.

By playing "IMAX Enhanced" content such as DTS: X's Ultra HD Blu-ray Disc and 4K streaming remastered by the sound engineer of IMAX theater in "IMAX mode" of this unit, IMAX faithfully to the creator's intention. Reproduces the powerful and immersive sound of the theater.

In addition, "MCACC Pro" enables playback in an ideal environment where the phases of each speaker are aligned and the sound connection between the speakers is good.

Newly equipped with "Audio Exclusive Mode" that specializes in audio playback by turning off the HDMI video signal circuit

By turning off the video output inside the AV receiver when connecting a device that outputs only audio from HDMI, such as a BD player equipped with HDMI separate output, a sound with a large amount of information and rich spatial expression is realized. increase.

* Only BD / DVD input is supported.

Newly equipped with "AV Direct Mode" that realizes high sound quality and high image quality by turning off the network function

By turning off unused network functions, the purity of audio / video signals is improved, and sound quality and image quality are improved.

There are Mode1 that improves sound quality and image quality by lowering the operating clock of the network module, and Mode2 * that completely turns off the network function, which can be selected according to the application.

* When Mode2 is selected, the HDMI output GUI cannot be displayed.

Adoption of new parts aiming for the best sound

[Block capacitor suitable for new amplifier]

With the evolution of Direct Energy HD amplifiers, the block capacitors in the power supply section have been redesigned. We have realized the reproduction of richer deep bass of the new Direct Energy HD amplifier.

[New resistance of non-magnetic plating made by Amtrans]

The electrodes on both ends of the chip use a new resistance with non-magnetic plating. It improves the accuracy of the DAC and contributes to the high quality of analog signals.

Thoughts on development

The history of Pioneer's AV amplifier began overseas in 1986, and in 2001, along with the spread of DVDs, the flagship model VSX-AX10 equipped with the world's first automatic sound field correction technology "MCACC" was developed. Then, in 2008, in order to realize the "multi-channel stereophonic philosophy" that is the design concept of our AV amplifier, we introduced the SC-LX90 equipped with the "Direct Energy HD (High fidelity class D) amplifier" of the first Class D amplifier. Developed. And until now, Pioneer's flagship AV amplifier continues to be equipped with that "Direct Energy HD amplifier". The reason is that the "Direct Energy HD Amplifier" is highly power efficient, and its output does not drop even when it is driven simultaneously with multiple channels, making it a very suitable amplifier for multi-channel drives.

Pioneer's flagship AV amplifier, which has continued to be equipped with the "Direct Energy HD Amplifier", has been evolving its sound year by year. As proof of this, when an engineer at the famous recording studio Air Studios in London, England, compared the new model developed with the reference machine of the previous year's model and judged that it exceeded all parts of the sound of the previous year, it was certified for the first time. This is because we have been developing to receive it. The SC-LX904 has not been certified, but this time our sound engineer has made the SC-LX901 exceed the sound quality in every part as before.

We developed this SC-LX904 in 2019 and sold it overseas. This time, with the help of GREEN FUNDING and parts suppliers, we are grateful to Japanese customers for the SC-LX904, the highest peak AV amplifier in Pioneer's history that surpasses all the sounds of this past model. We will challenge crowdfunding with a limited number of 150 units so that you can experience this evolution and experience the surprise and excitement.
