Instant Start within 10 ms (sound is produced immediately when the PLAY button is pressed)  
(a) FADER “Q” START CONTROL: This feature is used in conjunction with most American Audio® and American  
DJ® audio mixers that also feature “Fader Q Start” control. For best results use this feature with two (2) Pro-  
Scratch 2™ players. Connect your Pro-Scratch 2’s as described in the set-up section of this manual. After set  
up is completed load your players. By moving the mixer’s crossfader from left to right you can start and pause your  
Pro-Scratch 2™ playback functions. For Example, when using two (2) Pro-Scratch 2™ players and a Fader “Q”  
Start mixer, if your mixer’s crossfader is all the way to the left (player one is playing, player two is in cue or pause  
mode), and you move the fader at least 20% to the right, player two (2) will begin to play and player one (1) will  
return to cue mode. When the crossfader is to the right, and you move it 20% to the left, player one (1) will begin  
to play and player two (2) will return to its’ cue point. You can create great effects similar to scratching with this feature.  
After storing cue points on each side of the CD player, different songs or samples may quickly be recalled by moving  
the mixer crossfader back and forth. New cue points can be easily selected on the Pro-Scratch 2™ player (see setting  
cue points page 16). “Q” Start control is easy to use and mastering this feature will help you create amazing effects  
withyourmusic. Note:ForproperQStartoperationbesureyourmixersHamstersettingaresetto1/2(NormalSetting).  
(b) BOP EFFECT: The Bop Effect button serves two features. First, it is a stutter effect, creating a sound similar to a  
sampler. Second, it will return to the last Cue point in memory instantly. This will allow you to create great effects.  
To create the BOP Effect, see BOP Effect on page 21.  
(c) FLIP-FLOP: This feature is used in conjunction with American Audio® mixers that also feature Fader “Q” Start. For  
FLIP-FLOP results you must use two (2) Pro-Scratch 2™ players. Connect your Pro-Scratch 2’s as described in  
the set-up section of this manual. This feature will start the next player once one (1) player has ended. For example,  
if player one (1) is playing a disc and it ends, player two (2) will instantly begin to play. You may set FLIP-FLOP to  
play track to track or disc to disc. For more information on this feature, see FLIP-FLOP™ on page 33.  
(d) MEMORY BACKUP: The Pro-Scratch 2™ has a five (5) year memory back-up, that will save your setting in case the  
power supply is accidentally disconnected. Pro-Scratch 2™ will remember your last setting (repeat, SGL, CTN, and  
effect parameters) even if you disconnect your main power. The Pro-Scratch 2™ will store your cue points and  
samples in memory if you accidentally eject a disc or shut off the power. See memory on page 23.  
(e) PROGRAMMABLE CUE POINTS: The Pro-Scratch 2™ has three Flash Start Buttons (8). 128 Cue points can be  
stored in each of the FLASH START BUTTONS (6), for a total of 384. These cue points can be stored into the unit's  
internal memory and may be recalled at any time. See setting "Cue Points" on page 16
