CD player equipped with ACCU BIT system.

The D/A converter uses a left-right independent 18bitD/A converter, and is equipped with an ACCU BIT adjustment system to further improve the accuracy of D/A conversion.
The 18bitD/A converter consists of 18 pairs of precise resistor networks (ladder networks). When a digital signal is converted into an analog signal, this ladder network changes the voltage of the analog signal source. The slight error in the resistance value causes distortion and affects sound quality.
The conversion accuracy of the C-301FX is improved by the ACCU BIT system, which performs precise adjustment of the left and right resistor networks and corrects the error of the resistance value. In particular, linearity at the input of small signals is greatly improved.

The digital filter is equipped with an 8 x oversampling digital filter.
The sampling frequency is shifted to 352.8 kHz, which is 8 times the sampling frequency of 44.1 kHz, to keep it away from the music signal, thereby eliminating the influence of digital noise.

This system uses an optical transmission method to convert digital signals into optical switching signals for transmission. The optical transmission of data interrupts the electrical loop and prevents digital noise from entering analog circuits.

Equipped with a time edit function, recording can be performed according to the length of the tape.
If you enter the tape size using the TIME/EDIT and UP/DOWN keys, you can display the number of songs to be recorded on the A and B sides, start playing and recording, and wait for a pause when the last song on the A side is finished. If you play a CD together with the recording operation on the B side of the cassette tape, recording of the songs on the B side starts.

Wireless remote control is included.
