SONY DTC-2000ES AC100V

Description

SONY DTC-2000ES
A reference DAT deck born from the thorough pursuit of functions as a recording machine in order to bring out the performance and sound quality of DAT.
For recording with analog input, 44.1kHz mode is provided in addition to the conventional 48kHz mode (standard) and 32kHz / LP mode. This makes it possible to record in the same way as the CD format.
The front panel is equipped with a gold-plated microphone input terminal (standard jack x2). Furthermore, the microphone amplifier of a low noise design is carried and stereo live recording is possible.
It is said that the recording emphasis can be switched on / off to reduce harsh noise by emphasizing the high-frequency audio signal during recording and returning it to the original audio signal level with the reverse characteristics during playback.
In addition, the presence or absence of emphasis is automatically detected and switched during playback.
SCMS (Serial Copy Management System) is adopted as copy protection.
SCMS can record digitally → digitally for only one generation with a CD as the master, and digital → digital recording for the second and subsequent generations based on the tape obtained by recording is not possible. Similarly, if you use a source recorded with analog input, you can record digitally for one generation → digitally, but you cannot record digitally for the second and subsequent generations.
When using only analog input / output, you can record repeatedly without being restricted by SCMS.
In addition to one set of two heads for recording / playback, the head drum of a four-head composition which provided one set of two heads exclusively for a monitor is carried. This enables simultaneous recording monitoring that allows tape playback while recording.
It is equipped with a 4D.D. motor mechanism that uses independent direct drive motors for capstan, for both supply / take-up reels that fast forward / rewind tape, and for head drum rotation.
By installing a dedicated motor that does not involve belt transmission for each role, the load on the motor is reduced and the accuracy and stability of tape running are improved.
The newly developed pulse A / D converter with a built-in 1-bit system modulation is carried in the A / D converter. An excellent signal-to-noise ratio is obtained by executing high-speed and high-precision arithmetic of 64 times oversampling and 5th-order noise shaping.
Moreover, the influence of the noise on the modulator part which handles an analog signal is reduced by separating it from the decimation filter which performs the digital operation for returning a sampling rate, and making it an independent composition.
The newly developed SBM digital filter with a built-in decimation filter and SBM (Super Bit Mapping) is installed.
In the decimation filter section, the aliasing noise is banished by acquiring the original thrust of 120 dB or more by executing the high-precision digital calculation of 213 in total.
In addition, in the SBM section, the quantization noise that is uniformly distributed in the audible band is shifted to the high frequency range that is difficult to hear according to the human auditory characteristics, and the lower 4 bits of information that are normally truncated are noise-shaped. By using it and weaving it into the upper 16 bits, a significant noise reduction is realized.
The master clock is installed close to the A / D converter, and the A / D direct sink circuit which sends a high-purity clock signal is carried.
In the D / A conversion section, Sony's original high-precision calculation method is introduced, and the advanced pulse D / A converter that realized the high density of the pulse output is adopted. Harmonic distortion is generated by performing complementary PLM operation (differential synthesis of two pulse wave outputs that are complementary to each other) using a 1-chip IC with 1-channel 4D / A output and both-channel 8D / A output. It is decreasing.
Moreover, in DTC-2000ES, the separation characteristic is further enhanced by using this advanced pulse D / A converter IC in two chips independently for right and left channels.
The high-rigidity chassis which copper-plated the inside of the chassis is adopted in order to suppress the occurrence of magnetostriction by a vortex current and to reduce the impedance of a circuit. In addition, a high-rigidity aluminum top plate is used for the top plate, and a ceramic insulator is used for the legs to further increase the rigidity.
The software servo which made the motor servo by the microcomputer control into software is adopted.
As a result, in order not to put an extra burden on the tape, a high-speed and smooth search operation of up to 200 times speed (standard time) is realized during the search, slowly at the start and just before the stop.
In addition, the software servo has the effect of shortening the sound output time and improving the operability during cue / review operation.
The 3rd generation LSI that realizes even higher integration is mounted on the LSI that performs digital signal processing such as error correction and digital I / O. This simplifies the board configuration and enhances reliability and error correction capability.
The subcode function, which is also a feature of DAT, is installed, and start ID, skip ID, and end ID can be set and deleted.
The start ID is a sub-code that indicates the beginning of the song, except for auto that is automatically written at the start of the song and your favorite position (immediately after the start ID, 9 seconds in SP mode, 18 seconds in LP mode). ) Is equipped with two manual modes that can be written.
The skip ID is an ID that is written at the beginning of the part you want to skip and listen to when playing the tape, and if you find the skip iD during playback, you can automatically fast forward to the next start ID.
The end ID is a code that regards the written part as the end of the tape. It auto-rewinds during playback and stops during fast-forwarding.
The rehearsal function is carried in writing of the start ID, the writing of a skip ID / end ID, and the point writing of A-B repeat performed manually at the time of playback.
During the rehearsal, you can move the point back and forth in 0.3 second increments while listening to the sound and checking. The travel time is shown on the display and can be easily written to the just point. You can also modify the already written Start ID.
A program number can be assigned to the start ID, and you can directly select a song by simply specifying that number with the 10 key during playback. The program number is automatically assigned during recording, and can be renumbered by renumbering.
By adding or deleting the start ID, the renumbering function is installed to handle cases where the program numbers are not uniform. With this function, the number is renumbered from the beginning of the tape with one touch.
It is equipped with a shift serial number function that renumbers the start ID while reassigning it 0.3 seconds in advance.
Absolute time, which indicates the absolute time from the tape top, can be recorded.
The date function is carried and the built-in dedicated clock can automatically record year / month / day / day of the week / hour / minute / second / AM / PM in the subcode part at the time of recording.
Equipped with a time search function, when using a tape with an absolute time recorded, you can use this to move the tape back and forth in minutes to play or search for songs.
Equipped with an absolute time search, you can quickly search for the target location by directly entering the absolute and time of the place you want to cue with 10 keys in hours / minutes / seconds.
Based on the song you are listening to, you can play AMS, which allows you to find the previous and next songs according to the number of times you press AMS.
In addition, by using the AMS button and the 10 key together, the AMS search that can cue the number of songs before and after according to the number is also installed.
The program number search is carried, and by using the 10 key and the play button together, the music which recorded the program number of the pressed number can be directly cued.
Equipped with a music scan function, you can search for Start ID one after another and play it for about 8 seconds each.
Also, with the DTC-2000ES, you can change the playback time in the range of 1 to 15 seconds.
Repeat playback of the specified program number and the entire tape is possible.
Furthermore, with DTC-2000ES, A-B repeat that repeats between specified points is also possible.
The end search is carried and the end ID or the unrecorded part which has never recorded can be searched quickly.
By using the attached remote control, you can play 99 songs by rearranging the program numbers in any order.
Continuous recording is possible for up to 4 hours (when using DT-120).
The digital fade-in / out is carried and the fade-in / out can be performed during recording and playback. The fade-in / out time can be set in the range of 1 to 15 seconds, and is linked with the pause function.
The two types of digital input / output terminals coaxial with light are carried. Switching between optical and coaxial can be done with the switch on the front panel.
Moreover, the optical input uses the servo type digital signal normalizer circuit which absorbs the jitter by a cable.
Furthermore, it is also possible to turn off the digital output on the DTC-2000ES.
The digital peak margin display function is carried and it is possible to digitally display in dB unit how much more memory level is left at the time of recording.
The two fixed and variable output terminals are carried.
It comes with a wireless remote control that allows you to operate most of the main unit.
In addition, operations such as song selection and pause of Sony's remote control compatible CD player and CD synchronized recording operation are possible.
The fs map function using the digital peak level meter allows you to visually know at what sampling frequency the sound is recorded at an approximate position on the tape.
The Q code decoding function of a compact disk is carried. This makes it possible to decode the Q code, which is the inter-track information on the digital interface, and automatically write the correct start ID when recording a CD with digital input.
