Audio Recording on CD-R / RW: The CD-RW890MKII installs a digital optical input port and analog line-in input RCA ports.* The digital input CD-RW890MKII supports PCM sampling rates of 32 kHz, 44.1 kHz and 48 kHz and automatically records 44.1 kHz audio, which is the standard for audio CD sampling rate. Sync: the handy function automatically starts recording to an audio signal (analogue or digital) from a device such as a CD or MD player, and then stops recording when the signal stops.

In audio technology, it is important that the input signal and the output signal are as close as possible to each other, not damaged, distorted, and have phase and linearity.This is the most important aspect that NAD engineers rely on when designing NAD
