DescriptionSONY TC-KA3ESThis cassette deck is the basic model of the new ES series, developed with the technology of the advanced models.It is equipped with Dolby S NR as a noise reduction system. It introduces the Dolby SR technology used in professional equipment, and reduces tape noise to about 1/16th of its original level through precise signal processing.Furthermore, the breathing phenomenon peculiar to NR is suppressed by meticulously controlling the size and pitch of the sound.The audio circuit layout follows the signal flow as much as possible.The heavy mechanical deck is placed in the center of the front panel in a mid-ship mechanical system to minimize the negative effects of chassis distortion on the sound.A rigid half-hold mechanism is employed to prevent vibration and sound pressure that the cassette halves are directly subjected to.The cassette holder made of highly vibration-resistant fine ceramic composite material and the cassette stabilizer using sorbothane, which has excellent vibration damping properties, have been replaced with a dual-lock mechanism that locks the cassette holder on both sides, instead of the conventional one-lock mechanism. To ensure the effectiveness of the cassette stabilizer, the delayed action stabilizer mechanism, in which the stabilizer is crimped onto the half after the cassette lid is closed, secures the tape more securely.Super bias is employed to reduce interference caused by bias to the audio signal by keeping the frequency of the bias signal away from the audio signal bandwidth. In the TC-KA3ES, the bias frequency is shifted up to 160 kHz to reduce beat noise and intermodulation distortion.The TC-KA3ES is equipped with a 3-point REC calibration function to realize recording that makes the most of the tapes capabilities.The internal oscillator, which previously had two points of adjustment, is now expanded to three points (400 Hz, 3 kHz, and 15 kHz) to more precisely match the characteristics of the tape.The capstan motor uses a direct drive system with a 3-phase BSL motor to minimize rotation irregularities.Furthermore, a closed-loop dual capstan system is used to reduce wow and flutter by sandwiching the tape between two sets of capstan and pinch rollers to suppress modulation noise.The Lapis (sapphire capstan base) system, which uses high-hardness, low-friction sapphire for the bearing of the capstan motor, maintains stable running accuracy over the long term.Single-crystal oxygen-free copper ESC-OCC wires with purity of 99.997% or higher are used throughout the circuit for high quality and pure transmission.A buffer amplifier that lowers the output impedance is installed just before the output terminals, making it difficult to be affected by the superiority or inferiority of the pin cords used for connection to the amplifier. Eccentric insulators with mounting holes offset from the center are used, so that signals transmitted from the outside cancel each other out and are less likely to be transmitted to the chassis. The position and diameter of the holes were also studied through a series of prototyping and listening tests, and tuned to be effective in attenuating vibration components in the mid and high frequency range, which affect the auditory perception.The laser amorphous head uses a PC-OCC wound laser amorphous head that employs high-purity oxygen-free copper PC-OCC as the winding wire.Cassette halves are equipped with pads to press the tape against the head, but in the closed-loop dual capstan system, this pressure was excessive, which in turn increased modulation noise. To remedy this problem, a pad pressure reduction mechanism is employed, in which a slight convex projection is provided at the top and bottom of the head gap to release pressure from the pad. Dolby HX-PRO is equipped. The bias current is controlled in 1/1000th of a second increments according to the frequency and level of the signal to maintain linearity in the high frequency range. A FL linear counter with subtractive function is provided. The auto monitor function automatically switches the monitor sound from source to tape when the play button is pressed. A multi-AMS function is provided that allows the user to head out 30 tracks before and after the currently playing track as a reference.
