The full-scale 3 head cassette deck which challenged the threshold and likelihood of the cassette from the model which hits the sister machine of try marker Nakamichi 1000. The completeness 3 head scheme is adopted. It combines with the constant tension effect which a double gap capstan scheme induces by the recording head of a ferrite core, and the erase head and the reproducing head of the hard super permalloy core of the narrow gap of 0.7micro,Adhesion with a tapes also becomes good and is played by flat frequency response to a high region. In order to correspond to perpendicular gap of the tapes and head which the distortion on molding of a cassette case brings about, the recording head perpendicular regulating function with an alignment beacon is carried. A coordination is possible only by turning a thumb, carrying out the sound-recording play of the 400Hz built-in signal, offering the adjustment mechanism which a phase progresses and detects the output by delay, and seeing the blinking status of 2 issuance diodes. The control by IC logic circuitry is carried and all the tapes controls are operationals in one-touch. Moreover, the timing of the amplifier of a recording play, a bias oscillation, and an operation of a mechanism is also controlled completely, and is suppressing the occurrence of the it1 noise. The organization of the muting of tone, a memory counter, etc. is carried besides it. decibel peek level meter is carried in a level meter, and it does not have the care about the excess recording which occurs since a pointer cannot follow a sharp peek input like common VU meter. The threshold of the mechanism precision of a magnetic tape cassette is conquered from the closed-loop and double capstan drive side. With the using of a DC servo motor, up until last minute, it is large and properties, such as a wow and flutter, are improved by two flywheel effects which raised the effective mass. The switching unit of a low-noise tapes and a chromium tapes is carried. The property which suited each tapes by the corrective network in which a low-noise tapes has 120us and 1590us, and a chromium tapes has a time constant of 70us and 3180us has been acquired. The pitch control which can change tape speed ±6% by play is carried. The limiter circuit is built in, about 1/of excessive inputs of +3dB or more are automatically pressed down to 7, and the distorted occurrence is suppressed. The pickup is carried 3 point, the blend mike input besides a right-and-left channel input is prepared, and mixing of a sound effect, vocal, and a solo can be performed freely. The head base organization in which put in the damper organization and the degree of coherence with a tapes was received is adopted. The 0dB level calibration unit is carried and it can adjust according to a low-noise tapes and a chromium tapes. The Dolbey noise reduction is built in. The main motor of DC servo, and two motors of Mr. winding The cassette eject with a damper 19kHz MPX filter built-in A remote control is possible. A foolproof feather touch, a control push-button |
