Nakamichi CDPlayer3

Commentary

CD player using music bank system.

It uses a unique music bank system to enable multiple disc playback without sacrificing sound quality or operability.
The Music Bank System is equipped with a CD stocker inside and can store up to six CDs. Therefore, a total of seven CDs can be played together with the discs on the tray. This unique structure makes it possible to play a single CD with the same operability as a normal CD player. It also eliminates the mechanical noise and clumsy movement seen in the magazine system.

A total of 7 discs can be played continuously, 50 songs can be stored, and 7 discs can be played at full random.

A magnetic chucking type disk stabilizer is mounted on the tray part to suppress the influence of external vibration and to damp the resonance of the CD itself.

The digital filter uses an 8 x oversampling digital filter.
The analog filter is a third order linear phase Bessel type analog filter.

The D/A converter uses a linear 18-bit glitch free D/A converter.

The RF amplifier is placed not on the main board but on the pickup transport unit side, and the transmission path from the optical pickup to the signal processing circuit is greatly shortened to improve the sound quality.

Equipped with a digital de-emphasis circuit, it eliminates distortion factors such as switching circuits that are seen in analog systems.

Multi-regulated power supply system is adopted for the power supply section, and power is supplied independently for each circuit section.
In addition, the isolated ground method is adopted to prevent noise contamination between the digital circuit and analog circuit surrounding the ground line.

Equipped with a delete play function that can cut out songs you don't want to listen to.

It is equipped with a 3-way random play function of all / delete / program. It is also equipped with a 3-way repeat function of all / delete / program.

Single mode supports 8 cm CD.

Equipped with headphone port with level control.

Wireless remote control is included.
