from jvc Welcome to JVC's EXTENDED RESOLUTION COMPACT DISC 2 (xrcd2). The xrcd2 represents JVC's continuing commitment to the pursuit of digital audio perfection. This ongoing evolution of the xrcd series allows the discerning listener to participate in the results of JVC's research and development in both mastering and manufacturing, hardware and methodology. As with the entire xrcd series, no proprietary chips, processors, or special compact disc players are required to enjoy the sonic benefits of xrcd2.
In most cases after a record has been mastered, a U-MATIC 1630 format tape, PMCD, or DDP tape is perpared and shipped to the manufacturing plant At this point the artist, producer, and engineers can only hope their work will return to them in a relatively unchanged orom. This manufacturing chain is not standardized, and while digitally correct, does not always reproduce the highest audio qua;ity possible.Since the manufacturing process works as a number of components linked ttogether in series, the overall perfomance can be limited by each stage. This means extreme care and attention must be paid to every aspect of mastering and manufacuring to successsfully capture the original recorded performance.This was accomplished not by just measuring the results, but in extensive listening tests to determine the best configuration. Everyy combination of equiment, connection,AC power regulation, word clock distribution, mastering format delivery, and compact disc that offers clearer definition, more accurate imaging, and higher audio quality than any compact disc before.
The xrcd2 proxess starts at mastering. The analog signal is taken directly from the custom mastering console and digized using JVC's K2 20 BIT ANALOG-TO DIGITAL CONVERTER. The 20 bit digital word is then sent through JVC's DIGITAL K2, which is a digital re-generator. This 20 bit digital signal is then transferred toa a SONY PCM-9000, which stores the information on a MAGNETO-OPTICAL DISK. The xrcd2 process takes advantage of the stability of the MAGNETO-OPTICAL DISK, as well as its 20 bit capacity, by using it as the audio storage medium for delivery to manufacturing.
At the JVC manufacturing plant in Yokohama, Japan, the 20 bit SONY PCM-9000 MAGNETO-OPTICAL DISK is played back through the DIGITAL K2. This step climinates any jitter and distortion that might occur to the digital signal during playback. The 20 bit word is then converted to 16 bit using K2 SUPER CODING, which insures true 16 bit dynamic range. The 16 bit signal is then EFM encoded, and sent to the K2 LASER The K2 LASER re-generates the EFM signal right before going to the laser of the glass cuttrt. This last stage of the K2 eliminates any time based jitter that may be present in the data stream.
The end result of this mastering and manufacturing process is the highest wuality transfer from the original master tape to compact disc. This attention to detail allows the listener to enjoy the music in the same way the artist, producer, and engineers intended it to bo enjoyed. Every nuance of the oerformance is duplicated as it was recorded. This is the EXTENDED RESOLUTION COMPACT DISC 2 ...listen and compare.
