16. Reverse/Bleep Switch
Audio Reverse – Changes the direction of the platter and the music until it is returned to the upright
center position.
Bleep – Temporarily reverses the music from buffer while the unit continues forward motion. When the
toggle is released the unit resumes playing from the point where the song would be normally if it had not
been reversed. This is useful for "bleeping" out certain lyrics without interrupting the flow of the song.
17. Scratch Mode Button – Changes the way the music reacts to movement of the record.
Scratch – Allows the record to act just like a typical record on a turntable.
Scratch+FWD - Allows the record to act just like a typical record on turntable but only plays
forward actions. Hold "Scratch" for 1 second to get in the FWD mode.
Scratch+CUE – Moves the to the last set cue point each time the record is moved, allowing you to
scratch from the same point every time you move the record.
Scratch+CUE+FWD – Moves the to the last set cue point each time the record is moved, allowing
you to scratch from the same point every time you move the record, and only plays audio when
the record is moved in a forward direction.
18. Pitch Button - Adjusts the range of the pitch fader. Pressing this button will cycle through pitch ranges
of 6, 12, 25, and -100/+50%. Holding this button for 2 seconds will deactivate the pitch fader. Pressing
PITCH again will reactivate the pitch fader.
19. Pitch Fader - Controls the overall speed of the music and platter. At pitch settings of -80% to -100%,
the platter will deactivate and the music will be controlled by the slider. By moving the slider toward
"+", the music speeds up. By moving toward "-", the music plays more slowly.
To match the speeds of two units, you can either monitor the music of both units by ear, or use the
automatic BPM readout (on the top left of the display) and adjust the speed to match. When the tempo
of the music of the song you wish to match is slow compared to the tempo of the other song, move the
slider toward the (+) end and match the BPM. When faster, move the pitch slider toward the (-) end.
By making this adjustment the speeds can be matched, though the beats may not yet be aligned.
20. Key Lock – Holds the music at the current key. If the pitch slider is moved, the speed will change, but
the key will remain the same. By adjusting the pitch to -100% you can actually slow the music to a
complete stop while playing the last heard tones of the music. This works very well on vocals and can be
a very cool effect. If the unit has Key Lock active after the track has been changed and before Play is
hit, the unit will lock to a key based on the current pitch fader position. If "Key" is deactivated during
Pause, the unit will reset to match the current pitch position. If "Key" is deactivated during Play, the key
will remain at the new position until the track is changed.
To change the key of the music press and hold "Key Lock" while moving the "Track/Menu Select Knob".
The key can increase to 1 octave above normal, or up to 2 octaves above normal when the Slide effect is
used. The key can decrease up to 5 octaves below normal. The display will limit to 19 half steps above
or below the normal key.
21. Jog Wheel - This wheel is used for searching, adjusting the parameters of effects, trim, and key. When
the motor is off, this wheel is used to control pitch.
22. Search - Changes the mode of the jog wheel to "Search Mode". Search will remain active while the
wheel is being moved and for 8 seconds after.
through the music. Counterclockwise moves backwards through the music. Search will automatically
turn off after 8 seconds of non-use.
23. The Beatkeeper™ - Utilizes the latest patented Beatkeeper™ technology.
automatically tracks beats based upon a combination of frequencies and rhythm patterns in the music.
It shows BPM in the display and outputs 4-count (a.k.a. one measure) information about the music in a
marching bar graph.
The Bar Graph: Most dance music and rock is set up in 4 beat increments called measures. Many
of the features within the unit use this information for incredible results.

advanced features in the unit. The bottom LED is for the 1
music starts on the downbeat so the unit sets the first beat to where the music begins.
Occasionally this may not be correct or you may wish to reset it. To reset the downbeat simply tap
the "TAP" button at the new downbeat location as the music is playing or while in Pause.
TAP: This button is used for resetting the downbeat and also re-calibrating the BPM.
Beatkeeper™ is considered by many to be the most accurate automatic beat counter on the market
today; however, it occasionally may have trouble determining the correct BPM. This can happen
when the music contains complex rhythms, or if it starts without a beat at all. If you know the
BPM showing in the display is incorrect, or if the beat LEDs are not flashing with the beat, you have
2 options to reset the Beatkeeper™.

Press the Tap button on the downbeat and hold for a second. This will tell the unit to
re-calculate and display the next BPM it finds.
If holding the "TAP" button doesn't work, you can manually hit the "TAP" button on
the beat and the display will indicate the new BPM. The BPM will be based upon the
average of your last 8 taps.
