SONY MDS-JA3ES Mini Disk Deck Player Recorder Gold 1995 Tested Japan Description SONY MDS-JA3ES Sony MDS-JA3 ES: 108,000 yen (released in 1995) Description: This MD deck was developed using the high sound quality technology of the ES series. To take full advantage of the ATRAC format and further improve sound quality, we have introduced Wide Bit Stream, a 20 bit technology that performs a new type of arithmetic processing called block floating processing using the newly developed digital processing LSI for ATRAC with 20 bit input/output as the key device. In this process, we focus on dividing the processing into three bands, low, medium and high, and adopt a method in which the blocks with large data are left as they are, while the blocks with small data are calculated by raising the level of each block once. This enables playback of low-order bits that were traditionally truncated, greatly improving the reproducibility of miniscule music signals. The bit allocation algorithm that determines the bit allocation during compression has also been revised to improve the reproducibility of afterglow and reduce distortion. Newly developed A/D and D/A converters have also been adopted to match the high sound quality achieved by 20 bit technology. The D/A converter uses a newly developed D/A converter that integrates a full feed-forward digital filter and a 1-bit pulse generator developed for the New ES series CD players. In addition, the A/D converter adopts a newly developed 18 bit sigma-delta (sigma-delta) A/D converter with a high-precision oversampling method. It is equipped with a sampling rate converter that automatically converts the sampling frequency from 32 or 48 kHz to 44.1 kHz. In addition, the MDS-JA3 ES adopts the latest devices with 20 bit accuracy in both time axis and level to increase conversion accuracy. The power transformer uses an R-core transformer with excellent magnetic properties. In addition, a newly developed thin mechanical deck and power supply block are placed in the center of the chassis for a low center of gravity mechanical mount system that provides a highly stable structure that is not susceptible to vibration. In addition, we have introduced technologies common to the New ES series, such as the FB chassis, which has improved vibration resistance by rigidly joining the entire chassis, and eccentric insulators that suppress vibration transmission from the outside. It is equipped with a time machine recording function, and when you press the multi-jog dial in the recording pose state, you can record back to the sound of up to six seconds ago on the disc. You can automatically find and record unrecorded parts, start recording from the beginning of the song you want to erase, or start recording from the middle of any song. It is equipped with TOC EDIT function, title and date function which can record the title of about 1,700 characters and the date and time of recording. In addition, simple operation is achieved by installing a jog dial. It is equipped with two digital input terminals, one coaxial with the light. It also has an optical digital output jack. It has an L/R independent stereo microphone input jack. It has a smart space function that automatically adjusts between songs to about three seconds when recording digitally. It has a track marking function. It is equipped with a 22 segment digital peak meter. It has a disc in auto power function. It comes with a wireless remote that can be used in combination with a Sony CD player for CD synchro recording and other functions. Only playback is supported on mono format discs. It is equipped with a 4-megabit DRAM that memorizes music signals for up to about eight seconds to prevent sound skipping. In addition, taking advantage of the memory accumulation, we have made it possible to perform memory start playback, in which the sound starts immediately after the pause is released. With the SCMS (Serial Copy Management System), digital recording is limited to one generation, and no digital recording can be made after the second generation.
