Frequently Asked Questions
Q1: What is the power supply requirement for the device?
A1: The device requires AC 100 to 240V 50 or 60Hz.
Q2: At what tape speeds does the device work?
A2: This tape device operates on multiple tape speeds of 1-7/8, 3-3/4, 7-1/2, as well as 15 inches per second.
Q3: How does the tape respond in terms of sound frequencies at 7 ½ inches per second?
A3: The tape guarantees sound the frequencies ranging from 30 to 22,000 Hz +3 dB when the speed is adjusted to 7-1/2 inches per second.
Q4: What would the ratio in between the signal and noise level be once the line output is in use?
A4: While using the device at a tape speed of 7-1/2 inches per second, the ratio would exceed 48 decibels.
Q5: What is the timeframe for wind forwards and wind reverses?
A5: In both frequencies of 50 Hertz and 60 Hertz, it takes 85 and 70 seconds respectively for a tape of 1200 feet.
Q6: Is 3.0 percent distortion the maximum limit in terms of total distortion while operating at 3-3/4 ips?
A6: Yes, for all practical purposes, distortion must remain below the threshold of 3.0 percent while working at 3-3/4 ips.
Q7: Are there any limitations in terms of input requirements?
A7: The input requirement limitation for the line input include an impedance of 166 k ohm.
Q8: Is the device capable of working with stereo recording?
A8: Yes, in-line 4 recording of stereo and four track devices alongside monaural recording can be done with this device.
Q9: Can you elaborate on the kind of speakers attached to this device?
A9: There are 2 four inch woofers fitted into the device that has a resistance of 16 ohms and a power of 3 W.
Q10: Is it possible to explain to me the function of the erase ratio of the device?
A10: The ratio exceeds seventy decibels which is rather impressive.
