Pioneer SC-LX904 £2 499 11.2-channel receiver with 11 x215 Watt Direct Energy HD Amplifier, 6 HDMI Inputs (4K), IMAX Enhanced, Dolby Atmos, DTS:X, Zone 2/3, 32-bit DAC, Works with Alexa
The SC-LX904 comes with the 6th generation of the Direct Energy HD Amplifier and two ES9026PRO DACs, and is the befitting AV receiver to combine with Pioneer’s flagship universal disc player. MCACC Pro Auto Room Tuning technology featuring Full Band Phase Control brings out the best from the 3D surround sounds of IMAX Enhanced, Dolby Atmos, and DTS:X, while PQLS jitter-less transmission provides rich, lifelike audio. The new Audio Exclusive Mode and AV Direct Mode let you enjoy detailed sound by turning off the unused functions that affect quality sound reproduction.
Direct Energy HD Amplifier
Continuously evolving throughout the years, Pioneer’s Direct Energy HD Amp has now reached the 6th generation. New power coils are adopted for the ideal speaker drive, as well as new custom film capacitors co-developed with Shinyei Capacitor for the ultimate sound. The power supply and patterning has been developed through repeated tuning. Also, the entire transmission path from the pre stage to the power stage has been changed to balanced circuitry, to transmit noise-free high-quality signals to the power stage.
ESS 384 kHZ/32-BIT DAC
Two 384 kHz/32-bit ESS DACs (ES9026PRO), same as the ones used for Pioneers PD-70AE SACD player, are used for all channels. With extremely precise D/A conversion and high S/N ratio, the DAC provides powerful sound full of rich details.
Dolby Atmos/Dolby Surround Upmixing
The SC-LX904 is compatible with 7.2.4ch/7.2.2ch/5.2.4ch configuration of Dolby Atmos. You can reproduce object-oriented sound in smooth, curving movements, or the realistic three-dimensional movement overhead by the top speakers. Other
audio codecs such as PCM and DSD can be upmixed using Dolby Surround for enjoying 3D surround sound.
DTS:X/DTS Neural:X Upmixing
DTS:X is the next-generation audio codec from DTS that leverages object-based audio to enable new immersive and interactive audio experiences. Since DTS:X can automatically adapt the audio to the existing channels and speaker
system, no specific speaker layout is required. Experience an immersive soundscape with incredibly rich and lifelike audio. Other audio codecs such as PCM and DSD can be upmixed using DTS Neural:X for enjoying 3D surround sound.
2 Subwoofer Pre-Out
You can connect two powered subwoofers, and also set the volume level for each one at different levels.
PQLS Jitterless Sound Transmission
With the precision quartz controller on the AV receiver, Precision Quartz Lock System (PQLS) eliminates distortion caused by timing errors. It controls the amount of audio signals from the AV receiver to the Pioneer universal disc player connected via HDMI, giving the best possible digital-to-analogue conversion.
PQFA Jitterless Sound Processing for Network/USB
With PQFA (Precision Quartz File-based Audio), clocks are available for each stage of input, digital signal processing, and D/A conversion, and the shorter path prevents jitter from occurring. Additionally, a high-precision clock IC (OSC) is used to realise D/A conversion with significantly less jitter.
Audio Exclusive Mode
Interference from video signals is eliminated by turning off the video signal path via HDMI. You can enjoy detailed sound, full of spatial feel.
AV Direct Mode
The feature turns off the network functions to suppress digital noise within the AV receiver, and improves sound quality for analogue playback, digital input, HDMI playback etc. Mode 1 turns off the network module operation clock, while Mode 2 shuts down the network power completely for more superior sound.
Anit-Standing Wave Insulators
The Anti-Standing Wave Insulator features a special form with no parallel sides inside to prevent cavity resonance. This makes the sound localisation, tone, and scale clearer, while also enhancing the response to quick sound.
AC Inlet Type Thick Cable
A thick AC inlet type power cable is included to provide superior sound.
Quick Response Sound
The Direct Power FET is directly connected to the print circuit board without any additional wiring. This simple structure maximizes audio performance by reduced noise and improved switching, offering a quick-responding sound, perfect for digital content playback.
Improved Circuit Design
The SC-LX904 is equipped with dedicated ICs on the circuit board, all in the pursuit of delivering crisp, clean sound. The operational amplifier IC for processing small signal is set apart from the amplifying section to prevent mutual interference. This allows clear signal to be transmitted to the Direct Power FET.
Low Heat Generation
The simple form of the Direct Power FET has the advantage of improved thermal characteristics. In addition to the upper-side heat dissipation from the heat sink, the circuit board’s heat radiation feature is also utilized for downward heat dissipation, providing efficient cooling for a superior performance.
Separate Design for Analog Small Signal
Dedicated ICs are lavishly used on the circuit in pursuit of ideal sound. The Op-amp IC for processing small signal is set apart from the amplifying section to prevent mutual interference. This allows clear signal to be transmitted to the Direct Power FET. Additionally, the Rubycon chip film capacitor MU 25p further reduces the influence of residue noise from the high power section.
Low Leakage Flux Power Transformer
The power transformer features minimum leakage flux, ensuring low noise with increased S/N ratio.
Multi-Dimensional Excitement with Dolby Atmos
The SC-LX904 is compatible with 7.2.4 ch configuration of the latest theater immersive sound platform, Dolby Atmos. The SC-LX904 can reproduce object oriented compatible movies/music in smooth, curving movements, or the realistic three-dimensional movement overhead by utilizing Dolby Atmos enabled and/or in-ceiling speakers.
DTS:X is the next-generation audio codec from DTS that leverages object-based audio to enable new immersive and interactive audio experiences. Since DTS:X can automatically adapt the audio to the existing channels and speaker system, no specific speaker layout is required. Experience an immersive soundscape with incredibly rich and life-like audio.
The SC-LX904 comes with Chromecast built-in, so you can use your mobile device to stream your favorite music, radio, or podcasts to your speaker. You can control the audio from anywhere in the house using Chromecastenabled apps running on your personal device—iPhone, iPad, Android phone and tablet, Mac and Windows laptop, and Chromebook™. The SC-LX904 also works with the Google Assistant, so you can tell it to turn up the volume, skip tracks, or stop the music using your Google Assistant enabled device, like Google Home.

Ultra HD (4K/60p/4:4:4/24-bit) Upscaling/Pass-Through with HDCP 2.3
This feature lets you take advantage of the highest-quality video source for viewing on a 4K TV. With support for HDCP 2.3, you can enjoy premium content such as 4K videos with digital copy protection on a compatible display. What’s more, the SC-LX904 is ready for the HDR (High Dynamic Range) and BT.2020 next generation video standards.
When using Dolby Atmos-enabled speakers, high directivity sound from the unit reflects off the ceiling, while low directivity sound directly reaches the ears. The different pathways cause a phase shift, making the sound feel uncomfortable. The Reflex Optimizer which uses the Phase Control technology adjusts this shift, and improves the localization of the sound image by aligning the frequencies with those of the floor speakers, creating the ideal reproduction environment.
The SC-LX904 has 7 UHD inputs to cover all your UHD sources and ships with a 3 Year Warranty
