Sound Retriever

High-Performance Devices for Superior Sound Quality

Sound Retriever

Every Pioneer Elite A/V receiver comes with the newly- developed Sound Retriever, which significantly improves the sound of compressed audio — such as WMA, MP3, and AAC — to the level of CD sound. Sound Retriever creates new signals to restore the minute details left out during the compression process. This technology also enhances the audio quality of XM Radio.

The units also feature the latest Freescale DSP with about double the precision of conventional DSPs, which permits 48-bit processing.

The combination of the high-performance DSPs has enabled true 32-bit processing, permitting optimum sound quality, compatibility with all the latest surround formats, and the highest possible decoding capability.

Ultra Digital Core Engine 2 (VSX-84TXSi/VSX-82TXS/VSX-81TXV)

The VSX-84TXSi, VSX-82TXS, and VSX-81TXV benefit from powerful, state-of-the-art Freescale and Analog Devices processors. Both devices are used for pro audio gear for their exceptional performance.

The new Elite A/V receivers come with 32-bit floating point 3rd-Generation SHARC ® processor and Freescale 48-bit- processing processor.

With optimum processing power and decoding technology enabled by the Pioneer-exclusive "Ultra Digital Core Engine 2" design, the VSX-84TXSi, VSX-82TXS, and VSX-81TXV provide 96 kHz/24-bit superior-quality processing for the THX Select2 specification, DTS 96/24, DTS NEO:6, and Dolby Pro Logic IIx decoding, and multi-channel sound compensation (including Phase Control and Standing Wave Control).

Innovations in Construction and Materials

3-D Space Frame Construction (VSX-84TXSi/VSX-82TXS)

The 3-D Space Frame Construction is developed to clearly define the mechanical grounding of the chassis and make the structure rigid enough to support heavy weight. Perfected by repeated CAE strength analyses and auditions, this technology

Pioneer Video Converter (VSX-81TXV/VSX-80TXV)

Pioneer Video Converter features highly flexible conversion of video signals. It's capable of converting S-video and composite signals into component video signals, so they appear at the separate component video terminals. Pioneer's wide-band converter is even compatible with the 720p (progressive scan) format (through Component terminals). The Pioneer Elite A/V receiver comes with a number of monitor outputs that supply video signals to VCRs, monitors and other video equipment at the same time.

In addition to digital video converter, the VSX-84TXSi and VSX-82TXS can raise the original picture resolution to 480p, 720p, or 1080i. This lets you coordinate with the pixel count of

originally-designed Advanced Direct Energy Power Amplifier, featuring minimum energy loss and minimum interference between circuits. These features combine to deliver high-quality sound that is close to the original.

The device features "low-impedance, high-current" design, which minimizes the impedance at the final output stage. This effectively reduces the loss of the signals.

The advanced amplifier also reduces the electric/magnetic interference from the final output stage which significantly affects the sound quality. This is made possible by the compact design of the circuit — with the minimum size of the loop —

allows each part to deliver its maximum performance. Interference is also reduced by separating and insulating the power supply, amp, analog circuit, digital circuit, and video sections from one another.

Symmetrical Power Train Design

The Pioneer Elite A/V receivers each features power amps for seven channels. Accurate multi-channel sound reproduction is possible only when the

the connected monitor.

Up-scaling from 480i (interlace) to 480p/720p (progressive) involves interpolation of additional fields. With conventional technology, this interpolation often creates jagged edges along diagonal lines, especially during fast-paced action like football or hockey. The new Pioneer Elite A/V receivers overcome this problem by using DCDi(Directional Correlation De-interlacing) technology. DCDi's special algorithm fills in the information gaps that cause jaggedness, to make edges smoother and more natural.

32-bit Digital Processing by "The 3rd-Generation SHARC® Processor" from Analog Devices, Inc. and 48-bit processing DSP from Freescale, Inc. (VSX-84TXSi/VSX-82TXS/VSX-81TXV)

The VSX-84TXSi, VSX-82TXS, and VSX-81TXV incorporate "The 3rd Generation SHARC ® Processor" from Analog Devices, Inc., which is highly integrated to be used for audio equipment. The latest device boasts significantly

improved performance over the previous "SHARC Melody ® Ultra", a high-performance 32-bit DSP boasting dual processing capability. The 3rd-generation DSP delivers twice the performance and half the power consumption of the previous device.

for the final output stage.

What's more, the device features a new temperature compensation function for bias circuitry. Temperature of the output circuit is subject to change due to the speaker-driving current. The temperature fluctuations cause bias point deviation, which lowers the sound quality. The power amplifier for the new Elite A/V receivers effectively compensates for the fluctuations to minimize the bias point deviation.

operating environment of one channel is physically identical to that of the others. Therefore, with the new Pioneer Elite receivers, power output devices for the left channels (front, surround and surround back) are

mounted on the heat sinks symmetrically with respect to those for the right channels.

User-Friendly Operation

On-Screen Display

The Pioneer Elite A/V receivers feature simple, well-organized on-screen menus for the best home theater sound and customized A/V control via all video terminals, including component video. Using a handheld remote to interact with menus on your TV screen, you can assign the digital inputs, set the crossover point, adjust the time alignment, and do lots more, simply and easily. The on-screen instructions even help you recall preprogrammed codes for your remote control*.

*Available with 480i output via HDMI only. Please note some devices don't permit 480i output via HDMI.
