Commentary

A CD player with super-clean digital filter and FF-1 laser pickup.

The audio circuit uses a newly developed Super Clean Digital Filter newly developed digital filter.
As a result, unwanted noise components are eliminated without losing audio characteristics, and phase and frequency characteristics in the audio band are improved.

An original FF-1 laser pickup is used in the pickup part.
Compared with conventional pickups, this pickup has higher laser light utilization efficiency and significantly improved S / N ratio of reproduced signal. In addition, combined with the adoption of the digital accu-servo system with high signal reproduction capability, it has high playability against scratches and fingerprints on the disc surface.

A high-precision linear motor is used for the traverse mechanism to move the pickup, and the servocontrol of a newly developed microcomputer and a potentiometer using a CP resistor shortens the pickup movement between program tracks to an average of 0.8 seconds.

By using a non-magnetic lead frame in the D/A converter, the linearity at the low level is greatly improved. In addition, an SRC (delay time compensation) circuit is installed to offset the inter-channel phase due to the slight sampling time difference between the left and right channels, thereby obtaining accurate sound localization.

Equipped with an 8-digit FL multi-display.

Equipped with an auto-queue function, it automatically detects the real voice start part, and instantaneous start is possible in average 0.3 seconds.

Equipped with a programmable music scan.
With this function, you can play the head part of the recorded music one after another, and the monitor time can be set from 1 to 99 seconds.

It is equipped with programmable repeat function which can set the number of times.

Equipped with 2-speed manual search, you can switch from 3 x speed to 30 x speed by pressing and holding the key.

It is equipped with Auto Space, and you can set the music interval of 4 seconds automatically.

It is equipped with functions such as 20-track random program, one track / all track / program track / repeat between A and B.

Wireless remote control with 10 keys is included.
This remote control is equipped with a digital attenuator function and can be adjusted from 0 dB to -12dB in increments of 2 dB.
