Frequently Asked Questions
Q: What is the highest reel capacity of the tape for a 4000Ds?
A: Maximum up to 7 inches reel.
Q: The type of motor with which is installed on the 4000ds?
A: It uses a four poles induction motor type ssm-1.
Q: How can I change the recoding level on the 4000ds?
A: Set the monitor switch to TAPE , frequencies setting to audio oscillator, connect it to line input and finally adjust the recording level amplifier controls for the required output level.
Q: What is frequency response at a speed maximum of 7.5?
A: The frequency response is 7.5 ips 30 upto 23000hz
Q: Are 4000Ds able to record stereo type?
A: Yes, it has a 4 track recording system which is 2 channels stereo system type.
Q: How do I care for the equipment so that it works at its best?
A: Frequently and carefully examine, clean, adjust the heads, check the pinch wheel pressure, and use only quality tape for recording purposes.
Q: When do I have the wow and flutter in excess how do I monitor this?
A: Inspect, check the alignment of pinch wheel and capstan and re-adjust them if they are out of alignment as misalignment short-circuits the rotor or the motor.
Q: Does the 4000Ds allow the use of different tape speed?
A: Yes, It allows the 7.5 ips and 3.75 ips.
