Numark Industries CDN-34S Description Of Anti-Shockbuffer Memory, The Leader in DJ Technology

CDN-34S

DESCRIPTION OF ANTI-SHOCK BUFFER MEMORY

The CDN-34S is equipped with a total of 24 Seconds of RAM Buffer memory. 12 Seconds of this is used for the Anti-Shock Buffer and the other 12 are used for seamless looping, stuttering, and instant start functions. Anti-shock is to allow the unit to be bumped around hard for 6 seconds per side and not stop. When the CD is first placed in the tray and a track is selected, the CD player quickly reads the beginning of the track and stores it into a buffer memory, the same way a computer stores information in RAM. This initial operation takes about 5 seconds. As you play the track, the CD Player continues to read ahead of the music and stores this information in the buffer. If the unit is bumped the CD Player will continue to play from this buffer until the unit recovers and can start filling the buffer again. The buffer should be long enough to allow recovery from most situations, however, continual shocks can erase the buffer memory. If the unit should ever run out of buffer and still be receiving shocks, then the last 2 seconds will repeat until continuation can occur. The music never stops.

NOTE: The CD player can not store buffer information during the setting of a cue point with the jog wheel. If you start a CD without giving it an opportunity to load the buffer it will still start instantly and load buffer slowly. It will recover 1 second of buffer for every 6 seconds of music played at 0% pitch.
