Frequently Asked Questions
Q: Which approximate speed can this turntable work maximum?
A: DP-6000 turntable can work in maximum speeds of 45 RPM.
- Q: In what manner does the quartz crystal control system operate?
A: The quartz controlled alarm system has a division ratio of 33.75 kHz which is then divided down to meet the required oscillation frequencies.
- Q: Is there a limitation to how much the turntable's speed can be altered?
A: However, the turntable will offer its users a means through which they can manually control its speed and has ranges for its speed of approximately 20 percent on either side of the mean speed.
- Q: What is the function of the electric brake?
A: The electric brake is essential for limiting the time required for the turntable to achieve the standard revolution speed when the switch 33 1/3 rpm to 45 rpm is pressed.
- Q: Does crystal oscillator have any maintenance requirement?
A: The crystal oscillator does not require any change in settings as they are capable of adjusting itself with changes in temperature or humidity which makes it a low maintenance device.
- Q: For how many seconds is the brake operation set when the STOP button is pressed?
A: It was approximately calculated that the period of time consumed in the brake operation is 3-4 seconds.
