  1. What is a Peak Meter?
    A type of meter that responds quickly and shows all the peaks of a signal
  2. What is a V.U. meter?
    Volume Units. Shows average reading and doesn't show peaks.
  3. What is headroom?
    The amount of room you have before you clip a device.
  4. What is a clip?
    When the level exceeds your headroom and audible distortion occurs.
  5. Mic Level
    .001v (millivolts)
  6. Line Level
  7. Speaker Level
    1-70v, RMS voltage
  8. What is TRS?
    Tip, Ring, Sleeve
  9. How many connectors does a balance cable have?
    3 conductors. 1/4 inch
  10. List four types of EQ
    Sweep, Graphic, Parametric, Shelf
  11. What is a shelf EQ?
    It boosts (or reduces) energy at the set frequency and all frequencies above it.
  12. What is solo in place?
    Solos the channel to hear in relationship to overall mix.
  13. What are the advantages of VCA groups offer over regular sub groups?
    VCA groups allow the sound engineer to control the volumes of several independent sources through one control fader without having to route them all through a common subgroup
  14. What is a mute group?
    Allows the user to set up master mute buttons that will enable the mute function on specific groups of channels
  15. What is a Parametric EQ?
    Used in situations where very fine control over the audio signal is desired. Controls the Q.
  16. What is a Sweep EQ?
    Sweeps are commonly used to test equipment throughout the range of relevant frequencies
  17. What is a graphic EQ?
    The ONLY thing that makes an EQ "graphic" is this configuration of being able to see the curve at a glance. Contrary to popular belief there are graphic EQ's that have the same features as parametric EQ's, including Q controls and sweepable frequencies. Most graphic EQ's, however, only give you control of cutting or boosting a pre-selected set of frequencies at a pre-selected Q.
