(a) FADER “Q” START CONTROL: This feature is used in conjunction with American DJ mixers that also feature “Fader
Q Start” control. For best results use this feature with two (2) Pro Scratch 1 players. Connect your Pro Scratch 1’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 1 playback functions. For Example, when using
two (2) Pro Scratch 1 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 1 player (see setting cue points page 13). “Q” Start control is easy to use and
mastering this feature will help you create amazing effects with your music. Note: For proper “Q” Start operation be
sure your mixers “Hamster” setting are set to 1/2 (Normal Setting).
(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 15.
(c) FLIP-FLOP: This feature is used in conjunction with American DJ® mixers that also feature Fader “Q” Start. For
FLIP-FLOP results you must use two (2) Pro Scratch 1 players. Connect your Pro Scratch 1’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 18.
(e) MEMORY BACKUP: The Pro Scratch 1 has a five (5) year memory back-up, that will save your setting in case the
power supply is accidentally disconnected. Pro Scratch 1 will remember your last setting (repeat, SGL, CTN, and
effect parameters) even if you disconnect your main power. The Pro Scratch 1 will store your cue points in memory
if you accidentally eject a disc or shut off the power. To store your settings into memory hold down the MEMORY
BUTTON (7) for 5 seconds.
(f) PROGRAMMABLE CUE POINTS: The Pro Scratch 1 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.

9. SETTING and STORING a CUE POINT:
Setting A Cue Point:
A cue point is the exact point playback will begin when the PLAY/PAUSE (15) is pressed. You may set your
cue points anywhere on a disc or in a track.You may set up to four independent cue points per disk. Three cue
points are stored in the FLASH BUTTONS 1-3 (6) and one in the IN BUTTON (12). Figures 15 and 16 will detail
the procedures for setting your custom cue points. There are two (2) ways to set a CUE point:
1) You may press the IN BUTTON (12) on the fly (while the disc is playing). This
will set a CUE Point without music interruption. Pressing the CUE BUTTON (13) will
now return you to the same point that you pressed the IN BUTTON (12). You may
now store this CUE Point in any of the FLASH BUTTONS 1-3 (6). Pressing the
CUE BUTTON (13), BOP BUTTON (20) or the IN BUTTON (12) will now return
you to this exact point.
Figure 15
2) You may also use the JOG WHEEL (14) to set a cue point. While a disc is in
PAUSE or CUE mode, use the JOG WHEEL (14) to scroll through a track to find
your desired starting point. Once you have found your desired position press the
PLAY BUTTON (15) to set your cue point. Pressing the CUE BUTTON (13)
or the IN BUTTON (12) will now return you to this exact point.

BASIC OPERATIONS (CONT.)
Storing A Cue Point:
Once you have set your CUE Point by one of the two means listed on page 12, you may store your cue point
in one of the FLASH BUTTONS (6). Either a CUE POINT or a SAMPLE (See creating a sample loop on page
14) can be stored into a FLASH BUTTONS (6), not both. Once you store this cue point in memory you may
recall it at any time and you may even recall if the disc has been remove or power had been disconnected.
You may store a maximum of three cue points per a disc and maximum of 384 cue points can saved
in unit's memory. The MEMORY BUCKET (53) on the LCD DISPLAY (1) will approximate the available
memory. To Store a cue point:
1) Press the MEMORY CUE BUTTON (12), as in Figure 17. The red Memory Cue LED will glow indicating
memory is ready to be stored. You may now press any one of the three FLASH BUTTONS (6) to store
your cue point into memory (Figure 18). After pressing one of the FLASH BUTTONS (6), the corresponding
Flash Button LED will flash briefly. The LED will remain lit indicating either a sample or cue point is stored
in memory. The red Memory Cue LED will now shut off.
Figure 18
Figure 17
2) Repeat the above steps to store up to three Cue Points. Once all your three cue points have been
stored you may access them at any time. The cue points will instantly start without any music interruption.
Please note in order to access these cue point, the disc used to create the cue points must be in the drive.
10.CREATING AND PLAYING A SEAMLESS LOOP
A seamless loop is a sound loop that plays continuously without sound interruption. You can use this loop to
create dramatic effect in your mixing. This loop has no time limit and you could actually loop the entire length
of disc. You create a seamless loop between two continuous points of a disc.
1) Press PLAY/PAUSE
BUTTON (15) to
activate playback
mode
2) Press the IN BUTTON
(12). This will set the
starting point of the
SEAMLESS LOOP. The
IN BUTTON (12) LED

OUT BUTTON (18) LEDs will again begin to flash indicating SEAMLESS LOOP
mode has been activated (Figure 14) and your stored loop will immediately
begin to play.
Figure 23
11. EDITING A LOOP:
Please note you can only edit the ending point of the loop. You may make your loop shorter or longer. Before
you can edit your seamless loop you obviously must first have created a seamless loop to edit. If you haven’t
created a SEAMLESS LOOP, follow the instructions in step 10. If a SEAMLESS LOOP has already been
created, press the RELOOP BUTTON (19) to activate your SEAMLESS LOOP (Figure 23) if it is not already
playing. To edit your seamless loop’s ending point:
1) Press the OUT BUTTON (18) to return to normal play from the loops cue point. (Figure 20). This will
disengage the SEAMLESS LOOP mode and allows you to edit the loops ending point.
2) Press the OUT BUTTON (18) again when you reach your new ending point (Figure 21).

Changing the Sample Parameters:
Changing the sample parameters allows you to change the sample's volume and pitch. The
parameters values for both the pitch and volume settings range from 00:00 to 20:00, 00:00 being the
lowest value. A higher value will increase the pitch percentage or volume. It's important to understand
that the pitch value is basic a speed adjustment and has nothing to do tonal quality. The values can
be either a momentary change or set adjustment. The sample values are changed in three easy
steps, while in sample playback mode:

This feature is kind of “auto pilot”. When you are using two Pro Scratch 1™ players and an American DJ
“Q” Deck™ mixer, you can have one player begin playback when the other ends. You can “Flip Flop™” single
tracks, the entire disc, or a combination of the two.
To FLIP-FLOP™ single tracks:
1) Connect your system as described in the set up section on page 4.
2) Set your American DJ “Q” Deck™ mixer’s crossfader to the center position.
3) Set your two Pro Scratch 1™ to playback in single mode, SINGLE (43) should be indicated in the LCD
DISPLAY (1).
4) Load your two Pro Scratch 1™ with audio disc.
5) After they have both cued, press the PLAY/PAUSE BUTTON (15) on one of your drive to begin playback.
6) After the first player’s single track has ended the second player’s track will immediately begin playback.
7) FLIP FLOP™ will continue until you stop it or power is interrupted.
To Flip Flop entire CDs:
Be sure your drives are both in continuous play mode, make sure SINGLE MODE (43) does not appear in
the LCD DISPLAY'S (1) of both players. Follow all directions for single track FLIP FLOP™ above. When one
player’s disc ends the other player will immediately begin playback.
Note: You may combine FLIP FLOP™ single and continuously playback modes by selecting either single
or continuous playback on your units.
Connecting your Pro Scratch 1™ to an American DJ “Q” Deck™ mixer for “Flip Flop™” control: Be sure to
connect 1/8” mini plugs from the control connection on the rear your Pro Scratch 1 to the 1/8” control jack on
the rear of American DJ “Q” series mixer. That’s it, you’ll be set for FLIP FLOP™

17. PITCH BENDING:
This function will momentarily increase or decrease the tracks playback speed. There are two ways to operate
this function with the (-) & (+) PITCH BUTTONS (21 & 22) or with the JOG WHEEL (14). The maximum
pitch bend percentage allowed is +/- 100%. The pitch bend function will work in conjunction with the PITCH
SLIDER (17) pitch setting. The PITCH SLIDER (17) adjustment can be changed to range from +/-8%, +/-12%,
or +/-16% (See changing "PITCH SLIDER PERCENTAGE RANGE" on page 20). For example, if the PITCH
SLIDER (17) is set to a 2% pitch gain the pitch bending process will begin at 2% and will continue to
the maximum of -/+100%.
PITCH BEND BUTTONS (21 & 22):
The (+) PITCH BEND BUTTON (22) will provide a speed bump and the (-) PITCH BEND BUTTON (21) will
provide a slow down. 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 (22) is held down continuously, the disc speed will
increases and will continue to increase until reaches a maximum of 100% speed gain. When you release the (+)
PITCH BEND BUTTON (22) the disc speed will automati
c
ally return to it’s previous speed.

BASIC OPERATIONS - BUILT-IN EFFECTS
The Pro Scratch 1™ comes with nine built in effects. These effects can be used one at a time or you may
choose to overlap the effects and use up to four at a time. The Built-in effects include Scratch, Fade, Skid,
Coast,Flanger, Echo, Robot, Transform, and Pan. It is important to understand that only one effect per an effect
bank can be turned on at one time, but all four effects banks can be used at a time. For example the Flanger,
Echo, and Robot are all stored in the same effects bank but only one can be used at a time. When any
of the effects are activated, the EFFECT (42) icon will display in the LCD (1). You can choose to use the
effects with their default setting or you may choose customized each effect by changing the parameters. The
parameters values for all the effects will range. Some effects will have more adjustable parameters than others.
The parameters have two adjustable values, PR (Parameter Ratio) and PV (Parameter volume). All parameters
will be reset to there default values when power is shut off.

ROBOT EFFECT: The ROBOT effect is activated in the ECHO parameters. To
activate the ROBOT effect select the ECHO effect. After the Echo effect is activated
enter the PT Parameters and turn the hold function on. Set the Parameter Time
(PT) value to 0010 and use the Jog Wheel to create the effect by adjusting the
Parameter Ratio (PR).
FLANGER EFFECT: The FLANGER Effect has two adjustable parameters,
Parameter Time (PT) and Parameter Ratio (PR). The PT will adjust the Flanger
Mode and The PR will adjust the Flanger Frequency Range.
ECHO EFFECT: The ECHO Effect has two adjustable parameters, Parameter
Time (PT) and Parameter Ratio (PR). The PR will adjust the length of the echo (drop
off time), and the PT will adjust the echo gap length.
Figure 46
TRANS/PAN EFFECT: The TRANS effect simulates a real-time mixer transformer
effect. The PAN effect allows you to pan the output from the left channel to
the right channel. Pressing TRANS/PAN BUTTON (29) once will activate the
TRANSFORMER effect (figure 47). When the TRANSFORMER effect is activated
the TRANS/PAN BUTTON (29) will glow. To activate the PAN effect, press and
hold the TRANS/PAN BUTTON (29) until it begins to flash. A flashing TRANS/PAN
BUTTON (29) will represent the PAN effect. The fade time can be adjusted in the
parameters setting from 0010 to 9990. 9990 will give you the longest fade out time.
The Pan Value ranges from 10ms to ten seconds.
TRANS EFFECT: The TRANS Effect has two adjustable parameters, Parameter
Time and Parameter Ratio. The PT will adjust the Trans Speed and The PR will
adjust the Trans Audio Length. The lower the PT value the faster the TRANS effect
(PT 0500 = 1/2 second, PT 1000 = 1 second).
PAN EFFECT: The PAN effect uses the PT value to pan left to Right. PT 0500 is
the default setting which is center pan.

MATCHING THE BEATS PER MINUTE (BPM)
Beat matching is the act of finding the BPM’s (beats per a minute) of two different music sources, and
matching them together. After you have matched the BPM’s you use your mixer to fade the volume
in and out of one song to the next without music interruption while retaining the same beat. Use
the PITCH SLIDER (17) to match the BPM’s of one PRO SCRATCH 1™ to that of another PRO
SCRATCH 1™ or other music source. Use your mixer's crossfader to blend them in to each other
seamlessly. This is a function that may take some practice.
