  8. What are the 2 parts together called?
    I cycle of atmospheric pressure
  9. what are the characteristics of a waveform
    amplitude, frequency, velocity, wavelength, phase, harmonic content and envelope.
  10. what is the range of human hearing
    20 Hz to 20kHz
  11. what is another term for cycles per seconds
  12. what units of measure do we use to measure
    dB or decibels
  13. what is outboard equipment
    anything not connected to the console
  14. Name the 5 domains of outboard gear?
    Tonal, Time, Dynamic, Frequency and Spatial
  15. What is a parameter
    something that can be adjusted or controlled
  16. outboard gear can be broken down into to 2 groups what are they?

  17. What do you call the place all inputs and outputs are connected?
    the patch bay
  18. What are the two main rules?
    • Never connect an output to an output
    • Any line level output can be connected to any line level input, other than its own, if it is upstream in signal flow.
  19. what is a patch point
    Any individual jack that allows us to access our signal
  20. what is an insert point?
    Any pair of jacks that allows us to add an additional component to signal flow.

    a notch filter
  28. what is cutoff frequency?
    Any frequency that is reduced −3dB from normal.
  29. How is slope measured?
    dB’s per octaves
  30. What is a series of notch filters called?
