pitch adjustments

Pitch adjustments: The different pitch adjustments allow a track's or a loop's playback speed to be manipulated. This speed manipulations is commonly used to beat match between two or more music sources such as a turntable or another SD player. The playback speed may be increased or decreased by a factor of +/-16. The next section details the different pitch manipulation schemes. 1. PITCH SLIDER (25): This function will increase or decrease the tracks playback speed or "PITCH." The maximum pitch percentage manipulation in this function is +/-16%. The PITCH SLIDER (25) is used to decrease or increase the playback pitch. If the slider is move up (towards the top of the unit) the pitch will decrease, if the slider is moved down (towards the bottom of the unit) the pitch will increase. The PITCH SLIDER (25) adjustment can be changed to range from +/-4%, +/-8%, or +/-16% (See changing "PITCH SLIDER PERCENTAGE RANGE" on the next page). The PITCH SLIDER (25) will only effect normal playback and loops when the PITCH SLIDER (25) is active.

Figure 43

Activating the PITCH SLIDER (25): To activate the PITCH SLIDER (25) you must turn on the pitch adjustment function. To activate the PITCH SLIDER (25) press the PITCH ON/OFF BUTTON (11). The PITCH indicator will be displayed in the LCD, when the function is activated. If the pitch function is not activated the PITCH SLIDER (25) will not function.

Figure 44

Using the PITCH SLIDER (25): Be sure the pitch function has been activated as described above. To use the PITCH SLIDER (25) slide the slider up and down. Down will increase the pitch and up will decrease the pitch.

Figure 45

Audio - www.americanaudio.us - SDJ2 Instruction Manual Page 28
PITCH ADJUSTMENTS (Cont.)
Using the Pitch Slider Percentage Selector (10): You may choose a pitch operating range at any time. To change the operating range be sure the pitch function is turned on, see figure 44. The pitch percentage can be changed between +/-4%, +/-8%, and +/-16%. 4% will allow the least amount of pitch manipulation and 16% will allow the most amount of pitch manipulation. To adjust the different values, press the Pitch percentage Button (10) until your desired percentage is reached.

Figure 46

2. Pitch Bending: Unlike the PITCH SLIDER (25) adjustment this function will momentarily increase or decrease a tracks speed during playback. This is done using the JOG WHEEL (16). The maximum pitch bend percentage allowed by JOG WHEEL (16) is +/-100%.The pitch bend function will work in conjunction with the PITCH SLIDER (25) pitch setting. For example, if the PITCH SLIDER (25) is set to a 2% pitch gain the pitch bending process will begin at 2% and will continue to the maximum of +/-16%. NOTE: A -100% pitch manipulation will stop playback entirely. This can only be done with JOG WHEEL (16).

3. JOG WHEEL (16): The JOG WHEEL (16) will temporarily bend the pitch if a track is in playback mode, and the SEARCH BUTTON (17) is not active. Rotating the wheel in a clockwise direction will increase your track pitch and rotating the wheel in a counter-clockwise direction will slow your track pitch. If the JOG WHEEL (16) is continuously turned in a counter-clockwise direction the playback speed will steadily decreases and will continue to decrease until playback reaches a maximum of -100%. When you stop turning the JOG WHEEL (16) the speed will automatically return to its previous set speed.

pitch adjustments

Pitch adjustments: The different pitch adjustments allow a track's or a loop's playback speed to be manipulated. This speed manipulations is commonly used to beat match between two or more music sources such as a turntable or another SD player. The playback speed may be increased or decreased by a factor of +/-16. The next section details the different pitch manipulation schemes. 1. PITCH SLIDER (25): This function will increase or decrease the tracks playback speed or "PITCH." The maximum pitch percentage manipulation in this function is +/-16%. The PITCH SLIDER (25) is used to decrease or increase the playback pitch. If the slider is move up (towards the top of the unit) the pitch will decrease, if the slider is moved down (towards the bottom of the unit) the pitch will increase. The PITCH SLIDER (25) adjustment can be changed to range from +/-4%, +/-8%, or +/-16% (See changing "PITCH SLIDER PERCENTAGE RANGE" on the next page). The PITCH SLIDER (25) will only effect normal playback and loops when the PITCH SLIDER (25) is active.

Figure 43

Activating the PITCH SLIDER (25): To activate the PITCH SLIDER (25) you must turn on the pitch adjustment function. To activate the PITCH SLIDER (25) press the PITCH ON/OFF BUTTON (11). The PITCH indicator will be displayed in the LCD, when the function is activated. If the pitch function is not activated the PITCH SLIDER (25) will not function.

Figure 44

Using the PITCH SLIDER (25): Be sure the pitch function has been activated as described above. To use the PITCH SLIDER (25) slide the slider up and down. Down will increase the pitch and up will decrease the pitch.

PITCH ADJUSTMENTS (Cont.)
Using the Pitch Slider Percentage Selector (10): You may choose a pitch operating range at any time. To change the operating range be sure the pitch function is turned on, see figure 44. The pitch percentage can be changed between +/-4%, +/-8%, and +/-16%. 4% will allow the least amount of pitch manipulation and 16% will allow the most amount of pitch manipulation. To adjust the different values, press the Pitch percentage Button (10) until your desired percentage is reached.

Figure 46

2. Pitch Bending: Unlike the PITCH SLIDER (25) adjustment this function will momentarily increase or decrease a tracks speed during playback. This is done using the JOG WHEEL (16). The maximum pitch bend percentage allowed by JOG WHEEL (16) is +/-100%.The pitch bend function will work in conjunction with the PITCH SLIDER (25) pitch setting. For example, if the PITCH SLIDER (25) is set to a 2% pitch gain the pitch bending process will begin at 2% and will continue to the maximum of +/-16%. NOTE: A -100% pitch manipulation will stop playback entirely. This can only be done with JOG WHEEL (16).
3. JOG WHEEL (16): The JOG WHEEL (16) will temporarily bend the pitch if a track is in playback mode, and the SEARCH BUTTON (17) is not active. Rotating the wheel in a clockwise direction will increase your track pitch and rotating the wheel in a counter-clockwise direction will slow your track pitch. If the JOG WHEEL (16) is continuously turned in a counter-clockwise direction the playback speed will steadily decreases and will continue to decrease until playback reaches a maximum of -100%. When you stop turning the JOG WHEEL (16) the speed will automatically return to its previous set speed.
