BASIC OPERATION (CONT.)  
15. PITCH BENDING  
• This function momentarily increases or decreases the playback speed of a CD respectively when the  
+ PITCH BEND or - PITCH BEND button is pressed. The extent to which the speed changes is  
proportionate to the amount of time the button is pressed. For example, if the + PITCH BEND BUTTON  
is held down continuously, the CD’s speed increases and will continue to increase until reaches a  
maximum of 16% gain in speed. When you release the + PITCH BEND BUTTON the speed of the CD  
will automatically return to it’s previous speed.  
• The pitch can be changed from +/- 8%, +/- 12% or +/- 16% range. See changing PITCH PERCENTAGE.  
• The jog wheel will temporarily bend the pitch if a track is in play mode. Rotating the wheel clockwise  
will speed up your track and rotating the wheel counter-clockwise will slow the track down. The speed  
that you rotate the JOG WHEEL determines the percentage (%) of the PITCH BEND.
