Commentary
A DAT player announced at the same time as D-9000 as A & D.
The recording system is equipped with an LR phase-compensated A/D converter that eliminates the phase difference between the LR channels and realizes clear sound localization, enabling high-density recording of digital signals with high accuracy.
The reproduction system is equipped with a 4 x oversampling digital filter and L - and R-independent D/A converter that eliminates distortion and LR phase difference during D/A conversion and realizes faithful reproduction of the input signal and clear sound localization.
In order to eliminate the interference between analog and digital circuits, separate construction is adopted, and the circuit between analog and digital circuits is completely shielded.
In addition, the power supply section is composed of independent power sources such as analog, digital, display and mechanism. This completely blocks noise from entering through the power supply, and achieves clear sound by pure signal transmission.
High rigidity construction and high precision mechanism are adopted, and high rigidity and vibration resistance are realized by high rigidity zinc plated steel plate mechanism chassis, large pedestal and side wood.
As a result, adverse effects caused by unnecessary vibration are completely suppressed.
It uses a 4-motor system that realizes high-precision driving and comfortable operability.
Each of the DD capstan, DD drum, tape mounting, and mechanical drive is equipped with a high-performance motor. This makes tape running highly accurate and achieves high basic performance.
Equipped with an auto function that takes advantage of the characteristics of digital (subcode) recording.
Equipped with editing function by automatic start ID recording / manual skip ID recording.
Equipped with an optical digital input / output terminal that enables digital recording with little degradation of sound quality.
Wireless remote control included.
Available in 2 color variations, black and champagne gold.
