Continuously evolving throughout the years, Pioneer’s Direct Energy HD Amp has now reached the 6th generation. New power coils of the Pioneer Elite SC-LX904 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.

This Pioneer Elite SC-LX904 receiver is IMAX Enhanced, certified to deliver the powerful sound just as intended by the filmmaker, and provide the immersive experience on your home theater.

MCACC Pro, the pinnacle of Pioneer’s auto room tuning technology, analyzes the phase and group delay characteristics to precisely control phase differences between speakers. MCACC Pro corrects phase differences in all ranges and all channels of the Pioneer Elite SC-LX904, from phase difference in the original audio material to the sound emitted from the speakers. Required microphone included.

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 of the Pioneer Elite SC-LX904 provides powerful sound full of rich details.

With the Pioneer Elite SC-LX904 you can reproduce object-oriented sound in smooth, curving movements, or the realistic three-dimensional movement overhead by the top speakers.

Can automatically adapt the audio to the existing channels and speaker system, no specific speaker layout is required.

Pioneer’s Phase Control technology effectively eliminates phase lag and significantly improves the multi-channel sound without any extra operation. Furthermore, The Full Band Phase Control technology of the Pioneer Elite SC-LX904 focuses on the group delay in the speaker network filter, and adjusts the phase of each unit as well as the group delay for each speaker. Multi-range speakers gain the sound coherence of full-range speakers, while retaining the wide frequency range advantage. In an environment where the phase of all units and all channels are precisely controlled, a remarkably clear sound location with a surrounding feel is achieved. In combination with MCACC Pro, the ideal multi-channel reproduction environment can be created, which faithfully replicates object audio and the intention of the original content developer.

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-analog conversion.

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.

The feature of the Pioneer Elite SC-LX904 turns off the network functions to suppress digital noise within the AV receiver, and improves sound quality for analog 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.

Interference from video signals is eliminated by turning off the video signal path via HDMI. You can enjoy detailed sound, full of spatial feel.

Works with Alexa makes you control SC-LX704 with your voice via Alexa-enabled device such as the Amazon Echo, to play, pause, and skip titles or control the volume. You can enjoy the music via streaming service such like Amazon Music by selecting song title, artist name, release year, and genre.

Enjoy support for HDR (High Dynamic Range) video in the Pioneer Elite SC-LX904 including HDR10, HLG, Dolby Vision®, and BT.2020. The 4:4:4 color space is also supported. Six HDMI inputs, ARC-ready MAIN OUT, and SUB OUT pass 4K/60p and HDR video from player to compatible TV and projector and all terminals are HDCP 2.2 compliant.

The Pioneer Elite SC-LX904 features a special form with no parallel sides inside to prevent cavity resonance. This makes the sound localisation, tone, and scale clearer, while also contributing to seamless connection between the channels and improved response to quick sound.

Heavy-duty construction speaker binding posts allow for the use of thick, heavy high-end speaker cables that place lots of stress at these critical points.

You can connect two powered subwoofers, and also set the volume level for each one at different levels.
