  • Answer 41 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. Signal path in mixer - channels can be routed

2. If the compression ratio is made large enough - the compressor will actually become a limiter (above 4:1) - (electronics) an nonlinear electronic circuit whose output is limited in amplitude

3. Level of signal generated before it is amplified by the pre amp to line level

4. Are really rugged... Very sturdy -Takes a really high SPL level - Good: Takes a lot of pressure to make it move - Negative: Drums - Guitar amp - Live singing - inexpensive

5. Measure of opposition to a sinusoidal alternating current

6. Device that mutes a signal when it falls bellow a certain level

7. Any device used to increase signal level

8. The unit with which frequency is measured

9. The relationship of two wave forms

10. Boosts or cuts frequencies around a specified frequency

11. Difference between loudest and quietest SPL

12. A device that brings an electrical signal from microphone level to line level.

13. Picks up sound from front and a little more from back

14. Two conductive plates separated by an insulator. Capable of retaining an electrical charge

15. A metronomic click used during recording to keep musicians playing in time or audio engineers to set delay timings.

16. A cable capable of eliminating unwanted noise and hum that might be introduced along its length by carrying two versions of the signal - one with its polarity inverted.

17. Picks up sound from front and back of microphone but not the sides.

18. The directional response of a mic refers to its sensitivity (output level) at various angles of incidence with respect to the front (on - axis) of the microphone

19. Orb around the microphone can hear from any direction.

20. Unit of electrical current

21. Devices for cutting or boosting frequencies within a 3rd of an octave

22. Lowest frequency in a harmonic series

23. Sounds amazing - ribbon is corrugated but the ribbon can break if too loud - auto- compress sounds (all sounds will even out) - output it low - Similar to dynamic mics - but use a thin metal ribbon instead of a moving coil.

24. Shape of sound: Attack - Decay - Sustain - Release (ADSR)

25. Rate of repetition of periodic motion

26. Loudness or hight of a sound wave - Increase signal level

27. Measures the amount of amplitude applied to a signal

28. Picks up sound from front and a little from back of microphone

29. Different in charge levels between 2 conductive elements

30. Analog to Digital

31. Cycles sound wave makes in a second. 20 C = 20 Hz 20 -000 C = 20 -000 Hz (20-20 -000 average human ear can hear)

32. Needs external power (phantom power 48v) From mixer or mic pre - quality depends on the Voltage (48v or lower) - doesn't need as much SPL but is more fragile

33. It is used to proportionately reduce the dynamics of a signal that rise above a user- definable level (known as the threshold) to a lesser volume range. (below 4:1)

34. Lets frequencies below a certain level

35. Describes bandwith

36. When a processor like effects or compression is patched into a channel or group on a mixer/audio console - the processed signal supersedes and replaces the original.

37. Speed of sound. 1130 ft/s

38. Unit of power

39. Controls level in pre amp

40. A type of noise that is produced by combining sounds of all different frequencies together

41. Heart shaped: picks up sound from front of microphone only
