SONY TC-FX77

Commentary

In addition to linear electronic counter and Dolby NR / C type, this cassette deck is equipped with laser amorphous head and pre-end winker.

Equipped with a Dolby NR / C type noise reduction system.
The C-type has achieved noise reduction equivalent to three times that of the B-type, suppressing the breathing phenomenon. In addition, the C-type has improved the high-frequency characteristics of the tape. At the same time, it is equipped with a circuit that recommends distortion due to supersaturation. This improves the saturation level of the tape by approximately 4 dB at 9 kHz.
Also equipped with conventional Dolby NR / B type.

It is equipped with a linear electronic counter that also employs a subtraction function, and it is possible to display minus before 0 reset as a base point.
The TC-TC-FX77 is equipped with a pre-end indicator to let you know that there is not enough tape left when recording. When there are 2 to 3 minutes left on the tape, the 4-digit number on the counter starts blinking at 1 second intervals.

The recording and reproducing heads are equipped with a newly developed amorphous laser head with improved magnetic linearity and efficiency.
A magne-focus 4-gap F & F head is used for the erasing head.

It is equipped with a memory that memorizes the tape position of 0 count, AMS (automatic music sensor) that can freely select music and cue, and a repeat function that allows you to play repeatedly for a specified number of times.
Because these three functions are controlled by a single microcomputer, you can enjoy a variety of playback by combining them.

It is equipped with a peak hold meter that holds the maximum value for approximately four seconds and a double indication type peak program meter that simultaneously displays the signal level for each moment.

A DC servo motor with excellent rotational accuracy and stability is used for the capstan drive motor, and a DC high torque motor is used for the reel.

The direct connection between the playback amplifier and the head suppresses sound quality degradation caused by the coupling capacitor.
The audio circuit consists of a DC amplifier.
The power supply is ± 2 power supply system by FET.

Uses a slide volume.

Equipped with headphone volume.

Equipped with 4-stage tape selector with simultaneous switching of bias and equalizer.

Equipped with functions such as Rec Mute with auto space, continuous recording of absence / alarm clock playback with separately sold timer, Line/Mic automatic input switching, etc.

Uses a low-resonance flywheel that suppresses resonance by deadening.

Remote control unit sold separately allows operation from a remote location.
Also, by using the synchronized remote control unit, it is possible to play synchronized with the player and the playback deck.
