8-times Oversampling Digital Filter When a digital signal recorded on a CD is D/A converted in its original form with high-frequency noise, the 8-times oversampling digital filter in the DCD-F100 multiplies the signal’s sampling frequency by eight before it passes to the D/A converter. The noise that is thus clearly isolated from the musical signal is removed in the analog low-pass filter so that you can hear cleaner sound. Optical Digital Output A set of optical digital output terminals lets you record high-quality digital sound as is to a CD-R recorder unit.
