Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Cable wrapping method that reduces interference and makes it easier to unravel the cable.






2. Solid state version of the U67.






3. When miking an amp placing it near the center of this will make it sound brighter; Miking near the outer edge of this will make it sound darker and more mellow in tone.






4. Configured to simulate the spacing and directivity of human hearing; Box shape with two 'ears' on each side.






5. Used for stereo miking to ensure correct balance and imaging.






6. Radio Frequency Interference






7. The arm of the mic stand; Includes the angle adjust & telescopic adjust.






8. Condenser; Cardioid; End Address; 48V Required; Manufactured by AudioTechnica; Switchable 80 Hz Hi-Pass Filter; Ideal for professional recording and critical applications in broadcast.






9. Phenomenon causing carbon microphones to lose sensitivity as granules become packed together over extended use; To remedy problem mic is gently rapped on hard surface.






10. Keep in proper case; Never disassemble shockmounts






11. Condenser; Cardioid; Side Address; 48V Required; Large Diaphragm; Manufactured by Rode; Widely recognised as the world's quietest studio microphone; Ideal for vocals - voiceover - and acoustic instruments.






12. Solid State and Tube.






13. Divisions on the fingerboard which represent the position of a specific note or tone.






14. Dynamic; Cardioid; End Address; Manufactured by Shure; Popular musicians' choice due to its sturdy construction and ability to work well with instruments that produce high sound pressure levels.






15. Condenser; Cardioid; End Address; Manufactured by Shure; Small condenser design that is great for instrument recording.






16. Sensitive in a narrower pattern in the front than a cardioid and has a prominent/pronounced lobe at rear; Rejects most signals from 110






17. The first microphone sold by Shure; Military awarded Shure a contract to build microphones in WWII.






18. Small Diaphragm Electret condensers; Extremely flat frequency response; Omnidirectional pattern.






19. Small microphone attached to the bridge of a string bass or to an acoustic guitar to amplify its sound.






20. Used to make sure you have accurate angles & capsule spacing when miking in stereo.






21. Device used to calibrate sound pressure measurement devices; Emits a single 1 kHz frequency over a sustained period of time.






22. E = Blv - e - Electromotive Force (in volts) - B - is the magnetic field strength - l - is the length of the conductor - v - is the velocity of the conductor moving through the magnetic field






23. The head or top of the guitar where the tuning pegs are located.






24. Mic in which the diaphragm moves in response to sound waves and an attached pin/rod moves; Coil attached to pin/rod moves alone with the diaphragm.






25. Measurement similar to how our hearing works in frequency response charts.






26. Sounds that may be broadcast over the radio or internet.






27. Magnetic field opposite to that which presently exists; Do this on the bottom mic when miking a snare with two mics.






28. Stereo coincident pairing where the middle mic (usually a cardiod) is facing source and a bidirectional side mic is placed at 90






29. First microphone invented by Georg Neumann






30. Another name for condenser microphone.






31. The lowest - and usually most intense - frequency of a complex sound; Most often perceived as the sound's basic pitch.






32. Part of a mic stand that the mic stands on.






33. Big + & + (More front with less positive rear)






34. 4 to 6 ft. from the player; Mic should be placed below the line of sight of the bell - rotated at about 40 degrees off- axis - and tilted upward.






35. Small coil of wire wrapped around the plastic or aluminum diaphragm of a dynamic microphone.






36. Condenser; Cardioid/Hypercardioid; End Address; 48V Required; Manufactured by AKG; Can be powered by internal 9 V battery for field recording; Improves clarity of speech with the PB 1000 Presence Boost Adapter.






37. Condenser; Cardioid; Side Address; 48V Required; Manufactured by AudioTechnica; Ideal for project/home- studio applications; Low price; Remains the low cost performance standard in side- address condenser mics.






38. Modern drummer who has created a large kit and innovated several ways of capturing the sound from his massive kit.






39. Use coincident or near coincident pairings; Too many microphones will cause phasing issues.






40. Used to filter heating current in certain mics; Invented by Georg Neumann.






41. The first AKG dynamic microphone.






42. One of the world's greatest condenser microphones prized for the CK12 capsule.






43. Consumers can listen to live broadcasts over telephone lines; Individual one- way experience that required a subscription service to listen to performances.






44. Occupying the same space and time.






45. This is what is measured to produce an electrical signal in condenser mics; This changes as sound waves strike the diaphragm causing the distance to the back plate to change.






46. Most sensitive to sounds arriving from the front while rejecting sounds from rear; Shaped like a heart; Rejects most signals from 180






47. The part of the guitar you turn to tune the strings in order to get the right sound out of the guitar when one plays.






48. Microphone with 4 large diaphragm condenser capsules; 3 bidirectional and 1 omni; Can be combined to make any polar pattern.






49. Delicate and require extreme care; NO PHANTOM POWER; Becoming more popular than ever because of highly efficient magnets - lower manufacturing costs - and great fidelity.






50. Allows all high frequencies to pass; Blocks the lower frequencies from being processed.
