A/V RECEIVERS

The phase lag problem occurs during software production processes as well — through improper use of the microphone and Low Pass Filter — so Pioneer has also begun offering these technologies to software makers.

1080p Home Theater from Pioneer

Create a 1080p Home Theater System with Pioneer Elite Components

For the first time in the world, a comprehensive range of components for creating a 1080p home theater system is now available — thanks to Pioneer. These components include this year's Elite A/V receivers. You can connect a new Elite A/V receiver — VSX-84TXSi, VSX-82TXS, VSX-81TXV, or VSX-80TXV — to the PRO-FHD1 Elite Plasma Display Panel (PDP) and BDP-HD1 Elite Blu-ray Disc Player via an HDMI terminal (see page 38 for details). The receiver can send 1080p HD video signals from the Blu-ray player to the PDP with precise all-digital signal transmission — and no D/A or A/D conversion. The A/V receivers also deliver superb multi-channel sound from Blu-ray discs.

Phase Control — An Innovation for Multi-Channel Sound Compensation

Pioneer is one of the leaders in technological development and innovation for superior multi-channel sound reproduction. Now we have taken multi-channel sound a step further with patent-pending Phase Control technologies.

The objective of these technologies is to compensate for "phase lag" among channels, or in other words, the delay of some channels with respect to others.

The "Phase Control" Compensates for the Delay of Low-Frequency Sound

PHASE CONTROL

When amplifying multi-channel audio signals, receivers use a Low Pass Filter (LPF) for processing low-frequency signals for subwoofer output. It is this extra process that causes phase lag, an approximately 5 millisecond delay of low-frequency signals with respect to main channels. This is the equivalent of a 6.5 to 9 feet (2 to 3 meter) distance gap. The delayed bass affects the quality of main-channel sound, making the overall sound lack synchronization. Pioneer's Phase Control technologies apply a bass management system that effectively compensates for phase lag, to significantly improve multi-channel sound.

Phase Control Technologies

The latest Elite A/V receivers incorporate Phase Control technologies. These receivers come with

Phase Control function turned on by default, immediately ready to compensate for the phase lag between subwoofer channel and main channels. Combined with the new Advanced MCACC, this function even further optimizes your multi- channel sound.

Stereophonic Philosophy

Collaboration with Professional Sound Studios (VSX-84TXSi/VSX-82TXS)

Pioneer is dedicated to making your home theater experience as close as possible to what movie makers and studio engineers intended when they created the original sound tracks.

Working closely with AIR Studios sound engineers in the UK and George Lucas's SkyWalker Ranch in the U.S., the Pioneer team employed revolutionary processes in order to take your home sound system to the level of a professional sound studio. Professional sound engineers always start with three principles to achieve high fidelity recording and replay: quality reproduction, precision reproduction and artistic reproduction. Pioneer adapted this professional procedure to the design process so that the Pioneer Elite A/V receivers would recreate unprecedented audio fidelity in your home. This includes the best available audio components, measuring and calibrating the system with a microphone, and final sound tuning to preserve the original emotional elation of the music. With the professional master reference sound quality of Pioneer Elite A/V receivers, a concert at home has never been so spectacular.

recording studios in the world contributed an

unquestionable amount of expertise to these revolutionary multi-channel stereophonic receivers. The founder of AIR Studios is Sir George Martin, legendary Beatles producer and Academy Award-nominated composer — one of music's most versatile and imaginative talents. Established in 1969 in London, AIR Studios is now a state-of-the-art recording complex with matchless facilities for film scoring, rock, pop, classical and orchestral work, postproduction and live events. Many of the world's most popular and renowned musical talents have worked in this unique and inspirational recording environment.

Advanced Multi-Channel Acoustic Calibration System (VSX-84TXSi/VSX-82TXS/VSX-81TXV)

Multi-Channel Acoustic Calibration System (VSX-80TXV)

The Multi-Channel Acoustic Calibration System (MCACC) is Pioneer's revolutionary

answer to the dreams of stay-at-home movie and music fans. The world's first fully automated acoustic calibration system, the MCACC provides a studio-quality, multichannel listening environment by making delicate adjustments to neutralize the sound field of the listening space.

The VSX-84TXSi, VSX-82TXS, and VSX-81TXV moreover, come with an upgraded version of this technological wonder — Advanced MCACC with 3-dimensional compensation. In addition to speaker distance, sound pressure level and frequency response, the Advanced MCACC applies "time axis" in measuring the listening environment's acoustic characteristics and in applying frequency response compensation. This enables the system to distinguish between direct sound and room reverberation, resulting in even more precise, minute adjustment of frequency response for human ears. The Advanced MCACC also features "X-Curve Compensation" of frequency response — a living-room sized version of an international frequency response standard (ISO2969) used for designing movie theaters and dubbing suites.
