High-Power 7.1-Channel A/V Control Receiverseivers ----

A Host of Digital Technologies Applieded forfor Superior Sound, Pictures, and Stylele..

JVC now offers the latest-generation of AV control receivers -- RX-D702, RX-D402, and RX-D401 -- which feature a sleek profile to complement today’s and future home cinema systems.

But what gears the units for the future home cinema is not only the stylish design. Despite the slim dimensions, the units are ready to deliver powerful, high-quality sound from

various sources -- including PC music files -- and provide superior picture quality, too.

What’s more, their expanded connectivity lets you easily connect the units with your PC, and even permits HDMI connections -- the latest interface for transmitting audio/video signals.

Enabling these and many other feats are a host of advanced digital technologies newly incorporated into the units.

In this technical guide, you will see the details of those technologies and find how the advanced A/V receivers will upgrade your digital home theater systems.

What is DCDi by FAROUDJA?

RX-D702 RX-D402

*Also applies to RX-D401

The new A/V receivers can convert video signal format to HDMI for display on a compatible monitor, whether the signals are from Composite, S-Video, or Component input.

In this process, the unit converts interlaced pictures to progressive ones -- a process known as “IP conversion” -- using “DCDi by FAROUDJA”, a renowned, high-performance device. It features a host of advanced technologies for noise reduction and reproduction of high-definition pictures, including:

3D Deinterlacer

Film Mode: Recreates the original film frames by accurately blending the fields back together in progressive scanning -- for images free of motion artifacts and with full vertical resolution.

Video Mode: Delivers pictures from video sources by eliminating jagged edges on diagonal lines.

3D Noise Reduction

Filters out the noise temporally, without smearing or ghosting of moving objects in the image.

VISUAL PROOF

Effect Examples (1)

3D Deinterlacer

A unique algorithm that identifies all the moving edges in a scene and adjusts the angle of interpolation at each pixel so that the interpolation always follows the edge instead of crossing it, eliminating staircasing or jagged edge artifacts.

Jagged Edges on Diagonal Lines

Smooth diagonal lines are also delivered by the 3D Deinterlacer.

*Also applies to RX-D401

Cross-Color Suppression

While composite signals are decoded, high-frequency luma information leaks into the chroma channel, generating noise that looks like flashing colors or rainbow patterns.

(2)Input signals are free of D/A or A/D conversion until just before output, which prevents conversion loss.

(3)Use of DSSS (Direct Sequence Spread Spectrum) modulation technology enables transmission of uncompressed signals with superior resistance against noise, which retains superb sound quality.

(4)Corresponds to 16-bit, 32kHz/44.1kHz/48kHz sampling rates.

Wireless USB Connection

User ID Learning Function & Auto Scan

RX-D702

User ID Learning Function

Auto Scan

To ensure security, the wirelss USB transmitter and the RX-D702 share a specific “user ID”. This means devices without the same ID cannnot receive signals from the transmitter. And when you replace the transmitter, “User ID Learning Function” would be convenient. This function lets you easily set up a new user ID, so that the unit can receive signals from the new transmitter.

Transmitter

The Wireless USB additionally features “Auto Scan”, which stops interruption from other signals in the same room. When the system is turned on, this function automatically detects electric waves from other devices -- wireless LAN, for example -- and selects a band that won't be interrupted by the other signals.

When the signal transmission is interfered by other waves while using the unit, simply press and hold the “Channel Key” (on the transmitter) for a few seconds. The transmitter automatically switches the band to a one that won’t be interfered by the waves.

3 CC Converter -- A JVC-Original Technology for Superior Sound

K2 Processing is the result of a close collaboration among JVC studio engineers, producers and hardware engineers, embodying the elaborate algorithms for a sound quality that is close to the master by professional standards. The CC Converter is one of its applications to improve the sound quality of not only pure audio sources but also compressed files, such as dts, Dolby Digital, and MP3. The CC Converter lets you experience a sound that is truer to the original master than ever. With the RX-D702,

front L/R channels are processed by the CC

Converter.

Digital audio started with Compact Disc and has since given birth to such super high-fidelity formats as DVD

Audio and SACD. There’s another trend in digital audio: compressed data formats. Music distribution over the

Internet, silicon audio using compact IC cards, and digital broadcast by satellite -- all these formats take advantage of audio compression technology. This means there are two diverging trends in digital audio -- higher fidelity and higher compression.

JVC is not only a hardware maker but also a software producer as well, so there has been a close collaboration between the hardware engineers and studio engineers for all aspects of digital sound production. “K2 Processing Technology” is one of the many improvements developed by this collaboration to achieve higher sound quality. It was implemented as the “Extended K2 Processing,” a critically acclaimed application to pure audio. The CC Converter is an adaptation of this technology for compressed music. Therefore, it improves the sound quality of both hi-fi sources such as CD and DVD (Linear Mode) and compressed music formats including MP3 and WMA (Compression Mode), benefiting a wide range of digital audio contents.

Problems with Digital Conversion

RX-D702

In digital audio, music is processed in digital form. The music played by musicians in a recording studio or a concert hall is picked up by a microphone and recorded in digital form, to be released for sale as packaged media, including CD. The consumers buy the CD to play on a CD player: the recorded music is converted from digital to analog for playback through an amplifier and speakers. The process of playing digital music involves analog/digital conversion and digital/analog conversion as shown below.

Process of Playing Digital Music

The sound quality of a signal depends on the following two factors when the signal is converted from analog to digital.

Quantization wordlength (bits), which determines resolution or the expression of music in the amplitude domain.

Sampling frequency, which determines the frequency response or the expression of music in the frequency domain.
