Description
A DAT deck equipped with a wideband (HS: High Sampling) mode capable of 96kHz high sampling. It uses a wideband mode that increases the sampling rate to 96kHz, which is twice the conventional 48kHz sampling rate. This expands the range to ultra-high frequencies and provides the smooth sound unique to broadband mode.In wideband mode, the signal processing LSI, capstan motor, and drum motor operate at twice the speed of standard mode, making it possible to record and play at frequencies exceeding 40kHz. Also, in broadband mode, the tape runs at twice the speed, so the recording time is halved.(Wideband HS mode is the same function as D-07s WIDE mode, but the name has been changed) Equipped with legato link conversion to bring it closer to the original signal waveform.This system performs digital signal processing on the signals recorded on the tape, and connects the data with a smooth function curve to reproduce a sound close to the original before being recorded on the tape. . Furthermore, by estimating the original signal before recording, it is possible to reproduce sounds of 20kHz or higher according to the 1/f attenuation characteristics, achieving more natural sound reproduction. Equipped with a long-time (LP) mode that achieves twice the recording time of standard (SP) mode when recording analog inputs and recording digital inputs with a sampling frequency of 32kHz. This allows continuous recording of up to 4 hours with a 120 minute type tape. The head uses a high output AT head.The head has an all-track structure with a uniform track processing of 20 ?m in the track tracing direction. Glass is welded to both sides of the head to ensure wear resistance, and the gap is also specially polished. By applying this, a stable tape touch is achieved. The conversion section employs a newly developed 1-bit wide range linear A/D converter and a high-speed pulse flow 1-bit D/A converter. The 1-bit method has excellent linearity and has the feature that there is no generation of nonlinear distortion or zero cross distortion in principle, and it reduces conversion errors at the time of minute signals and improves linearity. It is equipped with a TOC function that records information such as the program time and the length of each song at the beginning of the tape.With this function, it is possible to manage information such as the total number of songs and total time, the length of each song, the start time of each song, and the remaining time of the recorded portion, etc., even with DAT. Equipped with high-speed AI search and subcode application functions, it reads the subcode information recorded on the tape, learns the song number and song start position, and uses these to increase the speed up to approximately 300 times (approx. 600x) high-speed AI search.It is also possible to record and delete various time information, start ID that indicates the beginning of a song, skip ID that is useful when skipping parts that you do not want to listen to, pole number information, end ID that indicates the end of recording, etc. . You can register up to 60 characters of data such as song title, performer, memo, etc. at the beginning of each song (start ID part). Data can be recorded either on the remote control or on the main unit, and the recorded information is scrolled and displayed on the counter display at the start of each song. Equipped with a CD-Q code synchronized start ID recording function, when recording digital input from a CD, the start ID is automatically recorded using the track number and index in the CD-Q code data transmitted to the D-05 via the digital interface. can. In order to eliminate the adverse effects of clock signal fluctuations, a clean clock circuit is used that separates the clock signal from both the audio system and the digital system.This clears the oscillation of the clock that controls the system and drives it independently to improve S/N and distortion. The chassis uses a honeycomb chassis with excellent vibration damping characteristics, and a midship structure with the drive mechanism located in the center improves weight balance and suppresses vibration and resonance.Furthermore, in order to effectively suppress the vibration of the cassette half, it is equipped with Pioneers original cassette stabilizer, which holds the cassette half firmly by sandwiching the cassette half with special rubber on the top and bottom, and pressing it down with resin at two places on the left and right. It is fixed. Equipped with a last memory function, AUTO ID on/off and input switching status are recorded even when the power is turned off. Carefully selected parts are used to support broadband expansion.
