3 CC Converter -- A JVC-Original Technology for Superior Sound K2 Processing is the result of a close collaboration among JVC studio engineers, CC Converter Background 18 Problems with Digital Conversion 19 Problem: An analog signal of a very faint strength cannot be accurately recreated by A/D and D/A conversion. (1) 20 one of its applications to improve the sound Problem: A high-frequency analog signal cannot be accurately recreated by A/D and D/A conversion.
CC Converter Background 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.
CC Converter Problems Problemswith with Digital Digital Conversion 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.

When the level is low, however, a stepped waveform results due to the limitation in the resolution of a digital signal.
CC Converter Problem: Problem: AAhigh-frequency high-frequencyanalog analog signal signal cannot cannot be beaccurately accuratelyrecreated recreatedby byA/D A/Dand andD/A D/Aconversion. conversion.(2) (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.
CC Converter CC CCConverter Converter RX-D702 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.
CC Converter Bit Bit Expansion Expansion Section Section RX-D702 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.
CC Converter Frequency FrequencyConversion ConversionSection Section RX-D702 The frequency conversion section doubles or quadruples the sampling frequency for playback of high-frequency signals that a following stage generates. Range RangeExpansion ExpansionSection 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.
CC Converter CC CCConverter: Converter:How How its itsworkings workingsdiffer differfrom from other other high-bit/upsampling high-bit/upsamplingsystems 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.

The TI Aureus™ chip ensures high-speed processing for equalization, while it executes various decode processing (Dolby Digital, dts, etc.) An analog equalization circuit is built from resistors and capacitors, therefore noise and phase reversal are inevitable.
JVC exclusive DSP 3D 3DHeadphone Headphone RX-D702 RX-D402 *Also applies to RX-D401 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).

JVC exclusive DSP Center-Channel Center-ChannelAlignment Alignment RX-D702 RX-D402 *Also applies to RX-D401 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.
JVC exclusive DSP Smart SmartSurround SurroundSetup Setup RX-D702 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.
