MCACC Pro Auto Room Tuning
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, from phase difference in the original
audio material to the sound emitted from the speakers. Required
Full Band Phase Control
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 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
Advanced Sound Retriever
The Advanced Sound Retriever restores 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.
When using Dolby 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 new 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. The result is overall
seamless sound with Dolby enabled speakers, allowing the ideal
reproduction of threedimensional surround sound.

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
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
