AKAI CD-A30

Commentary

A CD player that takes advantage of the potential of CDs and pursues high sound quality.

It uses anti-resonance construction that pursues vibration control of the player body.
First of all, an insulated pedestal using a new material, anti-resonance special rubber is adopted for the insulator to efficiently absorb external vibration. Inside the player, a double insulated floating mechanism is adopted by combining rubber and spring to mechanically insulate the mechanical block from the main body.

A newly developed 3-beam laser pickup is used in the pickup section.
Among the three beams, the メインレ laser spot of the middle sound picks up music information with high sensitivity, and the sub laser spot placed slightly shifted on both sides reads the tracking signal and quickly detects errors.

The sound quality is improved by strengthening the power section, such as by adopting a large power transformer and improving the power circuit.
In addition, since the sound quality is adversely affected by large fluctuations in the servo amount, we have adopted a new servo control system with a small servo amount to reduce the load on the power supply and ensure stable reading.

It is equipped with random program play of up to 36 songs, repeat function and search function.

Uses a disk center support system to prevent scratches and dirt on the disk pit.

Subcode terminal is mounted.
