Advanced Direct Construction
Less is more in circuitry design. 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
The 3D Space Frame Construction is developed to clearly define the mechanical grounding of the chassis and make the structure strong enough to support heavy weight. Perfected by repeated CAE strength analysis and tests, this technology allows each part to deliver maximum performance. Interference is also reduced by separating and insulating the power supply, amp, analog circuit, digital circuit and video sections from one another.
The SC-LX901 comes with this Advanced 3D Space Frame structure, featuring precise framework design, separating the power supply block, and isolating the analog video/audio and digital functional blocks into specific compartments. This reduces interference by flat cables between the blocks and improves the operating characteristics to accurately reproduce even the most delicate signals.
The rigid trans-stabilizer acoustically insulates the transformer and eliminates unwanted vibration, enhancing sound clarity.
Anti-Standing Wave Insulator
The Anti-Standing Wave Insulator has been developed through repeated listening tests, featuring a special 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, and the response to quick sound. The insulator enriches the realistic spatial description for movies, and the space representation of a concert hall for music sources.
Separated Pre and Power Amplifiers Blocks
Being compact and highly efficient, the Class D3 amplifier has allowed remarkably smaller heat sink and greater flexibility in circuit design and layout, and the ideal separate structure with independent pre and power amplifier blocks is realized. Additionally, the power supply for digital and analog circuits has been isolated to provide clean power, significantly contributing to clear signal transmission which is the basis for high-quality sound.
Clean Grounding with Insulated Dual Chassis
Steel plates shield the power amplifier block to eliminate unwanted noise caused by mutual interference, while Pioneer original Insulated Dual Chassis connects the power amplifier’s chassis to the main chassis via special 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.
