D&M Professional, manufacturer of the Marantz Professional line of recording products, released the new CDR420. The Marantz CDR420 contains a hard disk for recording has cut-and-paste editing and a CD writer for burning Red Book-compatible audio or MP3 discs. An optional RPS420 rechargeable battery system is available to facilitate remote recording or power backup.

Because the CDR420 records 44.1kHz mono or stereo .WAV or MP3 files directly to its internal 20GB hard drive, it is capable of instant field editing: cut, copy, paste, insert silence and split track functions are all available. CDs can be burned in standard Red Book audio format or in ISO9660 data format containing .WAV and/or MP3 files. Multiple MP3 bit rates allow the user to specify the best combination of audio quality and record time.

Other CD features include the ability to read and display CD text information from standard audio CDs and a Copy CD function for copying audio discs. Auto Track Increment automatically creates track marks at user-selected intervals, and a Timer Record function allows users to program record start and stop times for unattended operation.

The CDR420 can read, display and edit ID3 tags on MP3 files; a standard PS2 keyboard can be used for easy text editing and instant file naming during recording, and adds shortcuts to system functionality. Built-in I/O connectivity allows fast uploading of data from the hard drive to a computer, and Windows XP disk tools (error check, defragment) can be utilized through the system’s I/O port. There are balanced XLR mic/line inputs with +48-volt phantom power and mic/line attenuation pads, as well as unbalanced line inputs on RCA and S/PDIF digital I/O. A stereo headphone jack and built-in speaker allow for monitoring in the field, and automatic record level, limiter and manual record modes enable the user to maximize input levels while preventing distortion. Recording filters help minimize background noise, audible fast-forward and rewind provide easy, quick locating within a track, and a 3-band equalizer optimizes audio quality on playback.

The firmware can be upgraded via CD or the I/O port for performance enhancements in the future.
