Commentary

DAT deck equipped with 2 ADC and 18-bit recording system.

The A/D converter uses a unique 2 ADC 18-bit recording system.
In this circuit, a small-level input signal is amplified by a factor of four, A/D converted by an A/D converter arranged independently on the left and right sides, and the output is reduced to 1/4 by digital operation. As a result, linearity in small-level signals is greatly improved and a high S / N ratio of over 94 dB is achieved.

The D/A conversion section uses a 4-DAC 18-bit conversion system.
This system uses a 4 dac configuration with two D/A converters for both the right and left channels, one for the positive signal side and the other for the negative signal side. Input digital signals are D/A converted individually, and only the high-linearity parts of each component are synthesized. In principle, 0 cross distortion, which interferes with the reproduction of small signals, is shut out. In addition, high resolution of 18 bits is obtained by high-precision control of the 4 dac processor, and together with the adoption of high-precision 4 x oversampling digital filter of the 266th order, the detail reproduction capability of music is improved.

The classAA method is applied to a total of eight locations, including sample-and-hold circuits, buffer amplifiers, and head amplifiers for recording and reproduction, thereby increasing the resolution in the middle and high range by accurate waveform transmission capability.
In addition, the power supply section is equipped with a unique active servo power supply regulation and low noise.

One optical and one coaxial input / output terminal is installed.

Three sampling frequency modes are available : 48 kHz recording / playback, 44.1 kHz playback, and 32 kHz recording / playback.

Equipped with an editing function, you can record or erase the start position (Start ID) and the start point of automatic skipping (Skip ID) on a recorded tape with dubbing as desired. In addition, the EDIT key for dubbing is equipped with. If you press the record / erase key for Start ID or Skip ID by mistake while the EDIT is off, the dubbing operation will not be entered and malfunctions will be prevented.

Equipped with auto mode, the start ID and number of songs can be recorded automatically when a silent part lasts for more than 2 seconds during recording.

Equipped with an unnecessary start ID automatic deletion function, it can be used for fine adjustment of the start ID recording position.

It is equipped with a high-speed renumbering function. With this function, when adding a music number to a newly recorded start ID, you can check the music number while driving at 100 times speed and correct only the part that should be corrected.

Equipped with 30-step program play function.
The unique CRV (Constant Relative Velocity) servo system realizes 200 x speed search, high precision program play and direct access.
In addition, the operability of the program reservation operation is improved by installing the continuous reservation key.

Equipped with a cleaning indicator.
If the rotary head becomes dirty, the cleaning indicator lights during playback and then flashes to request cleaning.

Timer recording is possible by using an optional timer.

On the display, you can see the total recording time (absolute), the recording time of each song on the tape (program), and the tape counter (counter).
It can also display the number of songs being played, the order of reservation, and the number of songs passed during search. It is also equipped with a digital response level meter of -60dB to 0 dB.

Equipped with an input switching key.
Select analog for normal recording, and digital for digital recording.

Equipped with the A-B repeat key, you can set any section and repeat playback up to 16 times.

Wireless remote control is included.

You cannot copy digitally from a source that contains a CD player or copyguard.
