Commentary

Microcomponent series B5 size cassette deck.

A 2-motor system has been adopted in which the motors for driving the capstan and reel stand are independent.
In addition, by adopting a special air chamber for the IC logic control system and mechanism, operability is improved and mechanical noise is reduced.

The logic circuit uses MSI (TC-9121P) that integrates 900 elements in one chip, reducing the number of components to less than half (volume ratio 1 / 4).

The mechanism uses a dual flywheel system. In this system, a sub flywheel is attached to the main flywheel directly connected to the capstan. The effect of this system is approximately 10 times that of the main flywheel alone. This reduces the size of the flywheel.

The power supply section uses a double-core transformer that reduces magnetic flux leakage to one eighth of that of the EI type and improves power supply efficiency. In addition, the power supply circuit is divided into the amplifier section, meter, indicator section, and control section, reducing mutual influence and enabling stable power supply.

Equipped with a tape selector switch, switching between normal and ferrichrome is possible.
Aurex AX tapes and chrome position tapes have special detection holes and are automatically set to the optimum position just by setting them.
You can check the tape position by the indicator under the meter.

Equipped with LED digital meter.

An AS (All Sendust) head is used for the recording / reproducing head.

It uses a direct loading system that enables accurate and quick attachment and detachment of tapes. In addition, the remaining amount of tapes can be checked by the lamp that illuminates the cassette window from the back.

It has a built-in Dolby noise reduction system.

Built-in output preset volume, AC outlet and microphone jack.

Uses a gold plated pin terminal.

It is equipped with mechanisms such as a memory counter, autoplay which automatically moves from the head to the play action when the tape is rewound, and timer setting mechanism which enables recording and playback with a timer.
Remote control unit (RM-15) sold separately can be used for remote operation.

There are 2 kinds of color variations, PC-D15 of walkers or rollators for the elderly Ler and PC-D15K of BlackCar Ler.
