Zelf gebruik ik het Marantz SD-60 casssettedeck, is een 3 kops deck dus bij opname naband controlle mogelijk.
SpecificatiesMarantz SD-60 (around the 1989 time) 3 head cassette deck developed by the concept in thorough investigation of the basic performance.
In order to realize an ideal tapes run, the run system mechanism is pursued thoroughly.
The newly developed precision die-casting solid construction head base is adopted, and parts which influence a run performance, such as a capstan & pinch-roller head block and a cassette guide pin, are unified. By the synergistic effect with a precision large-sized fly wheel with a large inertial mass, the run performance is raised by leaps and bounds.
Moreover, with the closed-loop dual capstan scheme which consisted of two capstans and pinch rollers, the head touch of the stable tapes is realized and a modulation noise and level fluctuation are improved sharply.
The load variation of the motor was reduced and the tape tension and head touch which were stabilized with the twin belt drive scheme which loses rotation unevenness are gained.
Furthermore, the original cassette half stabilizer which presses down a cassette half's oscillation in respect of a point was adopted, and a cassette half's fine oscillation and modulation distortion are reduced.
In order to achieve thorough low-noise-ization and to reproduce purer high-quality sound, the exclusive device developed for sound-recording amplifier is adopted.
The constant current drive scheme which can supply the sound-recording electric current to need was realized without being influenced by the inductive impedance of the recording head, the recording head and tape characteristics were rectified, and the flat frequency characteristic is acquired.
Moreover, the differential part constituted by low-noise FET is carried in the play equalizer amplifier based on the know-how of the phone amplifier circuitry cultivated with the high-class amplifier of the Marantz, and the S/N ratio is improved.
The high hardness permalloy excellent in magnetic property is adopted as the core material of a Recording-play combination head.
PC OCC (single-crystal-like high purity oxygen free high conductivity copper) which suppressed the signal loss sharply is used for the coil winding of a head, and the respectively optimal gap setups for a Recording play is performed to it.
Dolbey HX PRO who controls bias level according to the quantity of a high region signal is carried.
In order to enable the sound recording in the status best thereby always, the frequency characteristic of upper register is improved sharply.
2 mode change of the linear counter which displays the usual tape counter and the lapsed time of a Recording play in a part and a second is possible.
Moreover, mode character display is carried and all operating state is displayed on a display device in the characters, such as the digital character.
The digital peak level indicator is carried and digital display of the peak level up to 0dB - +12dB is carried out for 5 seconds at a 1dB step at the time of a sound recording.
Moreover, MAX peak level memory is carried, memory of the upper of a recording level is carried out, and the upper can be called at random by a memory call key.
QMS (quick music sensor) is carried and the head of music to listen to is pulled out.
One intro (for about 10 seconds) of AMS (automatic music scan) each music after another is reproduced.
The music under a repeat/play can be repeated and it can reproduce.
The blank skip which searchs a unrecorded fraction and fast forwards automatically is carried during a tapes play.
Functionalities, such as an auto tapes selector, a REC calibration, a cassette indicator, and an anti Lec indicator, are carried.
Three input terminals are carried and a direct sound recording is possible.
Fix and two variable output-terminals are carried.
Song selection and output level of music can be operated with attached remote control.
