Marantz CDR630 165,000yen (around the 1998 time)

Business-use compact-disk recorder corresponding to CD-Recordable/CD-RW.

Full conformance of CDR630 is carried out to Red Book, Orange Book PartII, and Orange Book PartIII, and all the compact-disk medias of compact disk (CD-DA) / CD-Recordable/CD-RW are availables. A CD-Recordable disk is renewable by a general compact disk player after a finalize. Moreover, if a CD-RW disk is a compact disk player corresponding to CD-RW which will appear from now on, it will become renewable after a finalize.

The XLR analog input, the RCA analog I/O, and the digital (coaxial/light) input/output are carried.

The compact disk-Sync sound-recording functionality which starts a sound recording is carried in a play and concurrent of the source.

The sampling-rate converter is carried and the sampling frequency also supports the sources, such as 32kHz and 48kHz.
Moreover, a selection of the digital full sound recording of 1:1 which bypassed the sampling-rate converter in the time of a 44.1kHz digital signal input is attained, and the disk manufacture with a higher quality is possible. A digital full copy corresponds, only when the digital source is 44.1Khz±100ppm.

The track increment functionality in which the 2 modes of auto and a manual can be chosen is carried.
In auto mode, since input level is detected, the analog source can also write in a track number automatically.

When using a digital media for the source, a track number or start ID is recognized automatically.

The design of a 19 inches of EIA x2U rack-mounted size is adopted.

Wireless remote control and the volume only for headphone are carried.
