Commentary

A CD recorder compatible with CD-R and CD-RW.In addition to the 44.1 kHz used for CD, a sampling rate converter is installed to support the 32/48kHz sampling frequency used for DAT and DVD.When recording digital sources such as CD, MD, DAT, etc., recording and stop operations are automatically performed according to the sending side. This includes a digital synchronous recording function that includes auto-finalize recording, which automatically finalizes after recording is finished.It is also equipped with a digital auto-fader function for automatic fade-in / fade-out operation.Equipped with a newly developed Strategy Control IC, combined with running OPC operation, the laser power and recording strategy are always optimized at the time of recording, making it possible to record without failure.Equipped with a Hi-bit Legato Link Conversion, it generates music signals up to 40 kHz based on the signal recorded on the disc to reproduce realistic sound quality.In addition, it has realized a quantization number of 24 bits exceeding the CD format, and the dynamic range is theoretically expanded to the limit of human hearing.In addition, in order to pursue accurate music signal transmission, we adopted Pioneer's original design philosophy, the Z-concept, which eliminates fluctuations in the time axis of digital signals.It uses multi-bit DAC24, which has the advantages of multi-bit DAC and 1-bit DAC.By providing eight levels in the amplitude direction, a 24-bit high resolution is obtained, and by faithfully converting data expanded by Hi-bit Legato Link Conversion, a resolution of 120 dB or more is achieved in a band of 40 kHz or more.Uses a 3-pole inlet cord.Wireless remote control is included.
