Introduced January 1998
The DF-2 combines data reading capabilities of the conrad johnson DR-1 Data reader with sophisticated digital to analog conversion circuits from conrad-johnson. The Digital Processor in the DF-2 utilized a bit-stream DAC, known for very low crossover notch distortion resulting in smooth, extended high-frequencies without edginess. Discrete audio devices are used in the final analog output stage.
Precise adjustments were made to the laser intensity and focus to assure accurate data retrieval. A sophisticated crystal controlled “reclocking” circuit in the DF-2 reduced jitter by an order of magnitude.
DC voltage are supplied to the audio stage and analog portion of the DAC chip by discrete regulated power supplies, using “cjd” polystyrene and polypropylene capacitors exclusively.
