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.
