vintage DENON DCD-1630 full size CD player Japan

A CD player equipped with a real 20-bit Λ (Lambda) S.L.C (Super Linear Converter).

The D/A conversion section features a real 20-bit Λ S.L.C.

This circuit uses a newly developed LSI in the LAMBDA (Ladder-form Multiple Bias D/A) method to split the digital data into two streams. Then, digital bias is applied in the positive and negative directions near the zero-crossing point to shift the signal, thereby eliminating zero-crossing distortion in principle.
