Product description

Class D³ Amplifier (Direct Energy HD Amplifier)
• With the Class D³ (Direct Energy High Fidelity class D) amplifier and MOSFET, the Direct Power FET, this receiver is ready to meet many A/V entertainment standards.

High-Power Simultaneous Multi-Channel Drive
• The SC-LX901's Class D³ amplifier has the ability to simultaneously drive 11 channels at 850 W power output while efficiently delivering dynamic content.

Quick-Response Sound
• The Direct Power FET is directly connected to the printed circuit board without any additional wiring. This simple structure maximizes audio performance with reduced noise and enhanced switching, offering a quick-responding sound suitable for digital content playback.

Designed for High Efficiency
• The Class D³ Amplifier has been designed with a simple structure to take a straight and short signal path, resulting in improved sound quality.

Improved Circuit Design
• The SC-LX901 is equipped with dedicated ICs on the circuit board in the pursuit of reproducing a clean, clear sound. The operational amplifier IC for processing small signals is set apart from the amplifying section to prevent mutual interference, allowing a clear signal to be transmitted to the Direct Power FET.

Low Heat Generation
• The form of the Direct Power FET provides enhanced 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.

Separate Design for Analog Small Signals
• Dedicated ICs are used on the circuit in pursuit of more accurate sound. The Op-amp IC for processing small signals is set apart from the amplifying section to prevent mutual interference. This allows a clearer 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.

ESS SABRE³² Ultra DAC
• The 192 kHz/32-bit ESS SABRE³² Ultra DAC (ES9016S) is adopted to deliver enhanced sound with low distortion and a high signal-to-noise ratio. It offers jitter-free performance for an audio reproduction with deep bass, maximizing the full potential of the receiver.

Low-Leakage Flux Power Transformer
• The power transformer features minimum leakage flux, helping to ensure low noise with an increased S/N ratio.

Multi-Dimensional Listening with Dolby Atmos
• The SC-LX901 is compatible with 7.2.4-channel, 7.2.2-channel, and 5.2.4-channel configurations of Dolby Atmos. It can reproduce object-oriented compatible movies and music in three-dimensional movement overhead by utilizing Dolby Atmos-enabled and/or in-ceiling speakers.

DTS:X
• DTS:X is the audio codec from DTS that leverages object-based audio to enable 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.

Google Cast Ready
• The SC-LX901 will feature Google Cast via a future firmware update. It is the same technology behind Chromecast, so you can use your mobile device to cast your favorite music, radio, or podcasts to the SC-LX901. You can control the audio from anywhere in the house using Cast-enabled apps running on your smartphone, tablet, computer, or Chromebook.

Ultra HD (4K/60p/4:4:4/24-bit) Upscaling/Pass-Through with HDCP 2.2
• With support for HDCP 2.2, you can enjoy premium content such as 4K videos with digital copy protection on a compatible display. What's more, the SC-LX901 is ready for the HDR (High Dynamic Range) and BT.2020 video standards. Supports up to 4K/60p/4:4:4/24-bit with HDCP 2.2 on HDMI inputs 1-5 and both HDMI outputs (main/sub).

MCACC Pro Auto Room Tuning
• MCACC Pro technology analyzes the phase and group delay characteristics to control phase differences between speakers in all ranges and on all channels, from phase differences in the original audio material to the sound emitted from the speakers. The required microphone is included in box.

Full Band Phase Control
• Phase Control technology is designed to help eliminate phase lag and improve the multi-channel sound without any extra operation. Furthermore, the Full Band Phase Control technology 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 clear sound location with a surrounding feel is achieved. In combination with MCACC Pro, the multi-channel reproduction environment can be created to faithfully replicate object audio and the intention of the original content developer.

Advanced Sound Retriever
• The Advanced Sound Retriever is designed to restore the output of compressed audio - such as WMA, AAC, and MP3 - to the level of CD sound. The technology creates new signals to restore the minor details left out during the compression process. Advanced Sound Retriever for multi-surround sound is compatible with DVD soundtracks featuring Dolby Digital or DTS.

Reflex Optimizer
• When using Atmos-enabled speakers, high-directivity sound reflects off the ceiling while low-directivity sound directly reaches the ears. This difference causes a phase shift, making the sound feel unbalanced. To solve this, the reflex optimizer technology optimizes the performance of your up-firing elevation speakers for your listening environment by aligning the phase of direct and indirect sound, matching the basic tone and optimizing the upward-oriented frequencies. This is designed to achieve seamless sound with Dolby-enabled speakers and an enhanced reproduction of three-dimensional surround sound.

Multi-Room Audio Offers a Variety of Ways to Enjoy Music
• The SC-LX901 will support FireConnect (powered by Blackfire) with a future firmware update. FireConnect is a wireless protocol that mirrors most audio sources connected to the A/V receiver - from vinyl to streaming audio - on separately sold FireConnect-compatible speakers in other rooms.

Advanced Direct Construction
• Advanced Direct Construction allows the shortest and simplest signal paths - from input to output, circuit block by circuit block - to reduce distortion that can be caused by transmission loss and to improve sonic clarity.

3D Space Frame Construction
• 3D Space Frame Construction is developed to more clearly define the mechanical grounding of the chassis and make the structure strong enough to support weight. Enhanced by repeated CAE strength analysis and tests, this technology allows each part to deliver upgraded performance. Interference is also reduced by separating and insulating the power supply, amp, analog circuit, digital circuit, and video sections from one another.

Trans-Stabilizer
• The trans-stabilizer acoustically insulates the transformer and virtually eliminates unwanted vibration, enhancing sound clarity.

Anti-Standing Wave Insulator
• The Anti-Standing Wave Insulator features a form with no parallel sides inside to prevent cavity resonance. This makes the sound localization, tone, and scale clearer while also enhancing the seamless connection between the channels. The insulator enriches the realistic spatial description for movies and the space representation of a concert hall for music sources.

Separated Pre- and Power Amplifier Blocks
• Being compact and efficient, the Class D³ amplifier has allowed a smaller heat sink and greater flexibility in circuit design and layout, achieving a separate structure with independent pre- and power amplifier blocks. Additionally, the power supply for the digital and analog circuits has been isolated to provide clean power, contributing to clear signal transmission.

Clean Grounding with Insulated Dual Chassis
• Steel plates shield the power amplifier block to eliminate unwanted noise caused by mutual interference, while its Insulated Dual Chassis design connects the power amplifier's chassis to the main chassis via insulators. The pre- and power amplifier blocks are electrically separated, enabling the optimal ground design for each block. With thorough clean grounding and elimination of interference between the circuits and load changes, the sound quality and performance equivalent to separate amplifiers combined within a single chassis is achieved.
