This model was produced exclusively for the domestic market in Japan. AC 100 V, 50 Hz / 60 Hz.
Do not hesitate to ask questions and make offers. A cassette deck corresponding to the basic model of the new ES series which was developed with the introduction of advanced technology technology. Dolby S NR is carried as a noise reduction system.Introducing Dolby SR technology used in professional equipment and reducing the tape noise to about 1/16 by performing precise signal processing. In addition, we are suppressing the breathing phenomenon peculiar to NR by carefully controlling the magnitude and the pitch of the sound. The audio circuit has layout according to signal flow as much as possible. A rigid half hold mechanism is adopted to prevent vibration and sound pressure directly received by the cassette half. In addition to cassette holders using fine ceramic composite materials with high vibration resistance and cabinet stabilizers using Sorubosenin with excellent vibration damping properties, we changed to a dual lock that locks cassette holders locked at one side on both sides, Furthermore, in order to ensure the effectiveness of the cassette stabilizer, the tape is fixed more reliably by the delayed action stabilizer mechanism that the stabilizer crimps to the half after the cassette lid is closed.
By separating the frequency of the bias signal from the audio signal band, super bias is adopted that reduces the interference that the bias gives to the audio signal. In TC - KA 3 ES, beat noise and intermodulation distortion are reduced by shifting up the bias frequency to 160 kHz.
In order to realize recording utilizing the capability of tape, 3 point REC calibration function is carried. By adjusting the adjustment by the internal oscillator, which was 2 points in the past, to 3 points of 400 Hz / 3 kHz / 15 kHz, it is now possible to more finely adjust to the characteristics of the tape.
The direct drive system by 3 phase BSL motor with less rotation unevenness is adopted as the capstan motor. In addition, by using a closed-loop dual capstan method that sandwiches tape with two pairs of capstans and pinch rollers to suppress modulation noise, wah / flutter is reduced. We adopted the Lapis (sapphire capstan base) system which uses sapphire of high hardness and low friction coefficient for the capstan motor bearings and keeps stable running accuracy for a long time. By using single-crystal oxygen-free copper ESC-OCC wire material with purity of 99.997% or more throughout the circuit, high quality and pure transmission are aimed at. By installing a buffer amplifier that lowers the output impedance just before the output terminal, it is less susceptible to the influence of superiority / inferiority of the pin code used for connection with the amplifier.It adopts an eccentric insulator whose position of the mounting hole to the chassis is offset from the center, mutually canceling the signals transmitted from the outside, making it hard to transmit to the chassis. Also considering the position and diameter of the hole has been studied overlapping prototype and audition, tuning has been done to demonstrate the effect on the attenuation of the middle and high frequency vibrational components affecting auditory sensation. PC - OCC winding laser amorphous head adopting high purity oxygen free copper PC - OCC for winding of laser amorphous head is adopted. The cassette half has a pad for pressing the tape against the head, but with the closed loop dual capstan type, this pressure becomes extra, which raises the problem of increasing the modulation noise rather than it. In order to solve this problem, we adopted a pad pressure reduction mechanism that creates slight convex projections above and below the head gap to release the pad pressure.
By controlling the bias current in units of one thousandth of a second according to the frequency and level of the signal, high linearity is maintained. The FL linear counter with subtraction function is carried. When the play button is pushed, the monitor sound automatically switches from the source to the tape The auto monitor function is carried. Multi AMS function which can search the beginning and the back of 30 songs with reference to the song being played is carried. There were two kinds of color variations, gold and black.
