Marantz CD R-630 (1998)
Little is documented about the Marantz CD R-630. The archive holds no manual, no measured review, and no official spec sheet. What survives from the period is Marantz Professional's own launch advertising, which ran in the UK recording press in late 1998 and introduced the machine (styled there as the CDR630) as a low-cost mastering recorder.
The ads made two claims worth keeping. The first was price. It came in well under £1,000, which Marantz said gave it an unusually large cost advantage over other CD-R recorders and over every other mastering format of the day (Sound-on-Sound, October 1998, p.19). The second was flexibility. The CDR630 would replay CD, CD-R and CD-RW discs and record audio to both CD-R and CD-RW media, using professional-grade discs (Sound-on-Sound, December 1998, p.35). The obvious target was DAT, which until then was the default for small-studio mastering. The CDR630 was positioned squarely as a cheaper, re-writable alternative (Sound-on-Sound, July 1998, p.45).
Beyond that, the record runs dry. Details such as converter chips, recording speeds, and output levels are not documented in the available source material. The few facts that do come from the contemporary advertising:
- Introduced 1998 under the Marantz Professional banner
- New price: well under £1,000
- Playback: CD, CD-R, CD-RW
- Recording: CD-R and CD-RW
- Marketed as a low-cost alternative to DAT for mastering
