SONY TC-3000SD

Commentary

Cassette memory 3000 that employs a frequency servo motor with FG.

A frequency servo motor with FG is used for the motor.
This system uses a frequency-generator directly connected to the motor shaft to generate frequencies proportional to the number of revolutions and to read and servocontrol the changes. This system uses frequencies that are not affected by aging or voltage fluctuations, enabling stable tape travel.

An F & F head has been adopted for the head, and various characteristics have been improved by the direct coupling method which directly connects the reproduction amplifier.

Equipped with a tape selector with 3 levels of bias and 3 levels of equalizer.

Equipped with a Dolby NR system that reduces high-frequency noise and improves dynamic range.

Uses a 4-power supply system that supports AC power, dry batteries, car batteries, and rechargeable batteries.

Equipped with a large VU meter.
In addition, it is equipped with a peak level indicator by LED to cope with a pulsating sound.

Equipped with a microphone attenuator that prevents the microphone amplifier from being distorted by excessive input.

Equipped with a Sony Limiter switch to naturally reduce the level only when the input is excessive.

It is equipped with a DC-DC converter to obtain high linearity and a stabilized power supply circuit to suppress voltage fluctuation.

It has a built-in monitor speaker with output of 700 mw.

Equipped with a memory light that turns on for approximately 10 seconds.

Equipped with auto shut-off mechanism.

Comes with a shoulder belt.

There was a carrying case sold separately.
