AIWA AD-F90M

Commentary

A 3-head cassette deck that supports metal tapes.

The CVC (Combination V-Cut) 3-head system is adopted for the head part which is a further development of the 3-head system.

Equipped with a FRTS mechanism, a flat frequency characteristic can be obtained for each tape by reproducing test signals simultaneously while recording them and fine-adjusting the bias amount.
In addition, a bias fine adjustment mechanism is also mounted.

The recording amplifier has a linearity of approximately 20 dB (0 VU) in order to be able to handle metal tapes with sufficient margin.

A dual motor system is used for the mechanism.

Equipped with a double needle meter.

Equipped with double Dolby system.

Equipped with a rec mute mechanism.

Microphone mixing is possible.

Equipped with timer standby mechanism and by using a timer sold separately, it is possible to record absence and play alarm clock.

Equipped with a peak hold function.

Equipped with Reck calibration.

Equipped with synchronous operation function.

Equipped with auto-repeat and memory repeat functions.

Equipped with an oil dump ejection mechanism.

It comes with a wireless remote control. The PCM signal is sent by infrared from the remote control, and the beam sensor on the deck catches it, so that you can record, play back, stop, fast-forward, rewind, review, queue, pause, and mute.
