Commentary
A compact CD player with a super linear converter.
A super linear converter is used for the D/A converter. By adding a correction signal to the D/A converter using a correction circuit, the D/A conversion error is reduced and 0 cross distortion is eliminated.
The filter circuit is equipped with a 9th order analog filter.
A 3-beam laser pickup is used for the pickup part.
In addition, the pickup unit is made into a sub-chassis configuration so that it floats from the main chassis, eliminating the influence of external vibration.
The amplifier section has a DC amplifier configuration.
It is equipped with a de-emphasis circuit and supports pre-emphasized CDs.
By separating the power supply for digital circuit and analog circuit, mutual interference between circuits is reduced.
By using LSI as much as possible in the digital circuit, the influence of digital signals on the analog circuit is reduced.
It has a program mechanism of up to 15 songs.
It is equipped with functions such as direct music selection, auto search and manual search.
It is equipped with a repeat function for all songs and program songs.
It has a headphone port.
Timer connection is possible.
