1. 1

   What is the primary purpose of the highlighted PHONO/LINE output switch on a turntable?

   

   A To select between 33 and 45 RPM B To select cartridge-level output or internally preamplified line-level output C To reverse the left and right audio channels
2. 2

   What is the function of the tonearm counterweight highlighted in the image?

   

   A To balance the tonearm and set the stylus tracking force B To adjust the platter's rotational speed C To amplify the cartridge output
3. 3

   Which statement correctly describes anti-skate adjustment?

   A It increases motor torque when the platter slows B It changes the cartridge's electrical output level C It applies an outward force to counter the tonearm's tendency to move inward
4. 4

   When using a two-point cartridge alignment protractor, what indicates correct alignment at each null point?

   

   A The cartridge body touches the protractor's outer edge B The stylus rests on the target while the cantilever follows the alignment grid C The headshell points directly toward the spindle at both targets
5. 5

   What is a common baseline for setting an adjustable tonearm's height?

   A Make the tonearm tube approximately parallel to the record during playback B Raise the rear of the tonearm as high as possible C Lower the tonearm until the cartridge body touches the record
6. 6

   A turntable produces a strong 50 or 60 Hz hum, and the ground lead shown is disconnected. What is the most appropriate first action?

   

   A Increase the tracking force B Engage quartz lock C Attach the ground lead to the mixer's grounding terminal
7. 7

   Why are direct-drive turntables generally favored for DJ performance?

   A They eliminate the need for a cartridge B They provide strong torque, rapid startup, and stable speed control C They automatically synchronize two records
8. 8

   What normally happens when quartz lock is engaged on a DJ turntable?

   A The platter returns to its exact nominal playback speed B The motor enters reverse playback C The stylus pressure is automatically recalibrated
9. 9

   What is the main performance purpose of a DJ slipmat?

   A To permanently bond the record to the platter B To increase the cartridge's output voltage C To let the record be held or moved while the platter continues rotating
10. 10

    Why is a spherical stylus profile often selected for back-cueing and scratching?

    A It reads digital metadata embedded in every record B Its rounded contact geometry generally tolerates multidirectional cueing well C It requires no tracking force
11. 11

    In the illustrated traditional external-interface DVS setup, which device belongs in the empty position between the turntable and laptop?

    

    A A DVS-compatible audio interface B A passive headphone splitter C A loudspeaker crossover
12. 12

    Low-frequency feedback causes the stylus and speakers to produce an escalating rumble. Which response is most effective?

    A Place the turntable directly on the subwoofer B Add more bass at the mixer C Isolate the turntable and increase its distance from loudspeakers
13. 13

    According to the standard cartridge lead color convention shown, where should the white headshell wire connect?

    

    A Right channel positive B Left channel positive C Right channel return
14. 14

    Why should a turntable be leveled before tracking force and anti-skate are calibrated?

    

    A A tilted base changes how gravity influences tonearm balance and movement B A level base automatically aligns the cartridge C Leveling converts a belt-drive motor into direct drive
