User ID Learning Function

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.

Auto Scan

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.

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.

Background

RX-D702

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

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

RX-D702

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.

< 19 >

CC Converter

Problem: An analog signal of a very faint strength cannot be

accurately recreated by A/D and D/A conversion. (1)

When its level is high, a 1kHz signal can produce a smooth waveform after the A/D and D/A conversion. When the level is low, however, a stepped waveform results due to the limitation in the resolution of a digital signal. This phenomenon occurs because digital quantization distortion increases as the levels are reduced.

A/D and D/A Conversion in Amplitude Domain

RX-D702

< 20 >

CC Converter

Problem: A high-frequency analog signal cannot be accurately recreated by A/D and D/A conversion. (2)

RX-D702

The “sampling theorem” says that, if the sampling frequency is more than twice as high as the maximum frequency of original signal, then the original signal can be retrieved by A/D and D/A conversion. With CDs, the sampling frequency is 44.1kHz, meaning the maximum frequency is band-limited to 22.05kHz. Therefore, the information on the waveform for over-

22.05kHz frequencies is not transmitted. Unless it’s sinusoidal, a signal contains multiple high-order harmonics. So does a square

wave. If the input is a 1kHz square wave signal, it retains its shape because much of the information on the waveform for harmonics is retained after the A/D and D/A conversion. But if the input is a square wave of a high frequency, the converted signal presents a rounded shape because of the absence of information on high frequencies.

A/D and D/A Conversion in Frequency Domain

CC Converter

CC Converter Block Diag ram

CC Converter

The CC Converter was developed to solve the problems with digital conversion by (1) increasing quantization resolution for low-level signals and (2) increasing the sampling frequency for high-frequency signals. Because bit expansion and oversampling alone do not guarantee better sound quality, the CC Converter features JVC’s original, advanced digital signal processing.

RX-D702

CC Converter

Hi-bit Expansion Processing

Bit Expansion Section

In the bit expansion section, the JVC-exclusive hi-fi processing generates a high-resolution 24-bit digital signal from a 16-bit signal. The process first analyzes the 16-bit digital signal to deduce the original analog signal before A/D conversion, and then applies hi-bit expansion to smooth the signal waveform. What’s more, the process ensures that the 24-bit signal preserves the same sound energy of the 16-bit digital signal.

RX-D702

< 23 >

CC Converter

Frequency Conversion Section

The frequency conversion section doubles or quadruples the sampling frequency for playback of high-frequency signals that a following stage generates.

Range Expansion Section

The range expansion section applies the JVC-exclusive range expansion processing to compensate for the conversion distortion that occurs when the analog signal is converted into a digital signal.

The human ear, it is said, cannot hear frequencies above 20kHz, but removing frequencies higher than 20kHz changes the waveform of audible frequencies, resulting in a signal that sounds different from the original. The range expansion section overcomes this problem by deducing the original waveform of a signal before A/D and D/A conversion and modifying the signal’s waveform accordingly. For playback of frequencies above 20kHz generated by this waveform processing, the range expansion section has a frequency conversion section preceding it.

CC Converter

CC Converter: How its workings differ from other high-bit/upsampling systems

RX-D702

There are several high-bit/upsampling processing systems on the market that claim to offer the same benefits as the CC Converter. They are all designed to create and add frequencies (harmonics) over 20kHz deriving from an input signal.

But we do not believe the mechanical addition of harmonics can ensure the faithful recreation of “musicality.” The sound generated by an instrument contains harmonic components. And it is the harmonic components that determine the tone of an instrument. The harmonic components of one violin are different than those of another. One player’s phrasing produces different harmonic components from one by others. Some instruments feature rich resonance, while others produce hardly any.

CC Converter

JVC’s CC Converter does not simply create and add harmonic components. It computes the data that was lost during the D/A conversion by taking advantage of JVC’s exclusive algorithms. This means the CC Converter has the processing power to recreate the original signal that should have been recorded -based on the digital signals for the audible range recorded on a CD.

Therefore, applying the same process for adding harmonic components is not proper in view of “musicality.” Reviewers of European audio magazines are highly critical of this approach. Moreover, the existing high-bit/upsampling processing systems use 2x sampling frequencies -- 88.2kHz for CDs to achieve a 44.1kHz frequency range, or 96kHz for DVD Video to achieve a 48kHz frequency range.

Accurate D/A conversion and reproduction of the recreated data requires a process to expand the frequency range of the analog signals. The frequency-range expansion of the analog signals to beyond 20kHz results in improved music data for the audible range. The CC Converter expands CD’s frequency range fourfold to 88.2kHz using 176.4kHz (44.1kHz x 4) sampling frequency. With DVD-Video, the frequency range is expanded to 96kHz, while the sampling frequency is 192kHz (48kHz x 4).

Aureus™ -- High-Performance DSP for Superior Sound Quality

JVC exclusive DSP -- implemented by the Texas Instruments “Aureus”™ DSP -simulates the acoustics of music venues. In doing so, it makes use of a vast amount of DSP-computed data for the creation of sound field patterns that conventional processing systems, based on field-measured impulse responses, have difficulties recreating. With JVC’s DSP, the sound fields are reproduced most naturally, with early reflections simulated realistically. More than ten years ago, JVC sent engineers worldwide to measure the acoustics of famous theaters and concert halls. JVC exclusive DSP embodies both the old know-how and latest technologies to make you feel you are there.

JVC exclusive DSP

JVC’s DSP

Listening to the 7.1-channel surround as processed by the JVC DAP (Digital Acoustics Processor) evokes a totally different surround sound experience from what you get from stereo or 5.1-channel sound. Listen carefully to the

5.1-channel sound of a DVD in its recorded form and you’ll notice it does not produce the sensation of being surrounded by sound.

JVC developed the DAP for one objective: to make the home theater audience feel as if they were in the best movie theater surrounded by an array of speakers to the left and right, and behind. Then they would feel enveloped in sound, with a helicopter, for instance, moving left to right, or front to back.

JVC exclusive DSP, as implemented by the TI Aureus™ chip -- embodies the algorithms of sound field recreation that are developed specifically for advanced home theater receivers. The sound field patterns are created on the basis of the computer sound field simulation technology developed by a leading concert hall construction company. Patterns of reflections are calculated based on the data of the sound fields of the concert halls, theaters and movie theaters.

JVC exclusive DSP

Sound Field Analysis (Ray Tracing)

The figure shows the paths of the “sound rays” as they propagate from a sound source (red, black and brown balls) to the receiver (blue ball). The DSP calculates the properties of a reflection sound (time delay and direction) from the paths of the sound rays. The simulation computations it does for 7.1-channel surround are different from those for 5.1-channel surround or for stereo. This means the DSP does optimal simulation computations according to the configuration of speaker setting.

The reason why sound field simulation by DSP produces better results than

one based on actual measured environments.

To recreate an environment’s sound field, a real hall or cinema’s sound field is measured for data. For measurements, a pulse noise is emitted, its direct and indirect sounds are picked up by microphones, and their data is recorded. This is the approach adopted by other home theater receiver/processor manufacturers.

But measuring the sound field of an existing environment entails inaccuracies in the methodology. For instance, microphones have different characteristics, from model to model and from unit to unit. The measured data gives clues to time and level of a sound, but not to the direction. Measurements are made only at selected spots. Softest sounds are not captured accurately.

RX-D702 RX-D402

*Also applies to RX-D401

Sound field simulation by DSP, on the other hand, can produce accurate data by supplying parameters, such as the shape of a hall, the shape and acoustic properties of interior materials, and the presence/absence of an audience. Because this data is not based on actual measurements that could be affected by the measuring equipment used or its inaccuracy, it allows the accurate recreation of the frequency response and even the direction of each reflection.

5-Band Graphic Equalization

A graphic equalizer lets you adjust the levels of center frequencies.

An analog equalization circuit is built from resistors and capacitors, therefore noise and phase reversal are inevitable. A digital equalization circuit performs its function in the entirely digital domain. Clarity and consistent definition are its advantages.

3D Headphone

In a typical listening room, sound from speakers you perceive consists of three elements: direct sound, early reflections (echoes from walls/ceiling/floor), and reverberation. These elements let you locate the sound source and recognize its size. This is called Head Related Transfer Function (HRTF).

Direct Sound Reflections

Sound Frequencies Detected in

a Typical Listening Room

In developing the 3D Headphone technology, JVC has applied an exclusive algorithm that divides the audio signals into the same three elements and conducts processing individually (convolution processing). This ensures that sound from headphones has the same realism, dynamism, and localization as that from multi-channel speakers.

High Sound Levels

Frequencies of Input/Output Audio Signals

The DSP divides input signals into three bands (LOW/MID/HIGH), and processes the signals so that low-level sound in each band will get louder and loud sound will be moderated. This makes the output sound clear across the range, regardless of the original levels.

Frequency

In addition, the unit individually controls the sound compression level of each band. When the sound level is low, the compression levels of

Level

high and low frequencies are raised to deliver enough loudness. When the sound level is high, the gains of the two frequencies are

moderated to prevent excessive bass and treble output. These technologies combine to retain the excitement of multi-channel

sound and keep dialog sound clear even at low sound levels.

The technologies are applied even when the sound level is lowered suddenly, which is especially useful for midnight viewing, for example.

Center-Channel Alignment

The center speaker is usually placed on top of or under the display, while the front speakers are set at or near ear level. The result is that dialog, carried by the center speaker, seems out of place relative to music and sound effects. JVC's exclusive DSP application virtually positions the center speaker to align it with other speakers with respect to height. The dialog simply sounds more natural.

Smart Surround Setup

Setting up a home theater can be time-consuming and even confusing. Normally, you have to check which speaker channels (front, center, surround, and surround back) you have installed, the distance of each speaker from the listening position, and the level of each speaker.

But with JVC's Smart Surround Setup Version 3.0, it takes just seconds to set up the acoustic environment of your home theater. Clap your hands, and the delay times of all channels are set individually, and the level of each speaker is automatically trimmed -- optimized for your listening positio n. You can even finetune the settings if you prefer. Setup information is displayed on-screen for easy confirmation.

Background -- What is PWM?

Pulse Width Modulation (PWM) is a method of digitally encoding analog signal levels. In the process, continuously varying value of input audio signals is detected based on the reference voltage (Vref) by comparing the signals with triangular waves. When the value is higher than Vref level, the pulse is switched “ON”, and when it gets below Vref, it’s turned “OFF”. The higher than Vref the value is, the longer the pulse is kept “ON”. The lower than Vref the value is, the longer the pulse is left “OFF”. Thus, square-shaped waves are generated, representing either “ON” or “OFF” state of the pulse -- length of the “ON” and “OFF” pulses expresses the value of audio signals with respect to the Vref levels. These waves are called “PWM signals”. Precision of the PWM signals is one of the elements that determine the sound quality delivered by a digital amplifier. This is why “feedback” process is essential for delivering high-quality sound.

Synchronization by an External Clock

Slight gap of frequencies among channels causes specific noise. To prevent this, the JVC amplifier uses an external clock, which synchronizes the operations of all channels. Noise is also generated when the unit receives AM signals whose frequency overlaps that of audio signals. The external clock detects this and automatically modifies the audio signal frequency of all the channels simultaneously, thus preventing the noise generation.

Usually, speaker impedance fluctuates according to the frequencies of audio signals.

This “frequency response” of the speaker in turn fluctuates the levels of audio signals. How effectively an amplifier can control these fluctuations is called “speaker driveability”.

The feedback processes of the Hybrid Feedback Digital Amplifier significantly improve the speaker driveability, retaining the same output level across the frequencies.
