  1. What is a microphone?
    A transducer that converts sound waves into a weak electrical signal.
  2. what is a transducer?
    A device that converts on form of energy into another.
  3. how does a microphone work?
    • weak signal sent to preamplifier
    • boosts signal to line level
    • sent to a power amp which boosts the signal to a level that will drive a speaker
  4. Extremely thin strip of corrugated metal suspended between the poles of a magnet.
    The air pressure of the sound waves vibrates the ribbon and induces an electronic current
    The voltage mimics the frequency and intensity of the sound source.
    Used for recording and sometimes in the orchestra pit.
    ribbon microphone
  5. The heart contains a magnet surrounded by a wire coil.
    One end of the coil is attached to the microphone’s diaphragm.
    When sound waves strike the diagram it vibrates which vibrates the coil.
    An induced current is generated that mimics the frequency and intensity of the sound wave
    Uses: onstage use and recording
    dynamic microphone
  6. Diaphragm of thin conductive materials forms one half of a capacitor.
    sound waves strike the diaphragm the pressure changes the space between
    the two plates. This causes a change in the capacitance of the
    The movement changes the voltage in the plates.
    The voltage change mimics the frequency and intensity generated by the source.Requires a power supply
    condensor microphone
  7. an electrical component consisting of two metal plates separated and
    insulated from each other. Used to store an electrical charge
  8. A method of supplying DC power through the microphone cable
    phantom power
  9. visual pattern illustrating the intensity of a microphone’s output relative to the direction the sound arrives
    polar patterns
  10. microphone used for –Speech and song. Picks up sound from the front and rejects a lot of sound from other directions
    cardioid microhpone
  11. microphone that Transmits the audio as a radio or optical signal rather than via a cable
  12. Small wireless mic to be worn on personal clothing, wigs, through the hair, etch
    wireless lavalier microphone
  13. microphone that will Pick up sound without by obstructive
    Good when you want to hear the feet
    floor microphone
  14. How are scored sounds gathered?

    • Live sources
    • Sound effects libraries (CDs and some others)
    • Online sound effects libraries
    • Online sources (YouTube)
  15. Sound sources are downloaded into a hard drive
    žEdited and created through Digital Audio Workstation (DAW) software
    žEdit multi-track sound effects
    Refine (trim, repeat, select)
    Effects (reverb, tremble)
    Sequence (layers, start)
    Laptop: supplement or replacement for sound console is becoming popular. Sound designer can edit on the fly

    digital audio workstation
  16. audio playback software
    • Playback Cues through the mixer
    • Edit Cues for Playback
    • –Loudness
    • –Fade
    • –Loop
    • –Speaker routing
    • Sequencing
  17. Boosts a low voltage signal received from the mixer to a high voltage signal needed to drive the speaker.
    Commonly capable of running at 10 times the average requirements of the speaker
    Serve any momently peaks in the average value of the speaker volume
    Sized appropriately for the speakers that they are driving.
    Too large will overheat
    Too small will distort
    power amplifiers
  18. how speakers work
    • Transduces the electrical signal from the amplifiers into sound waves
    • The signal activates an electromagnet attached to the loudspeaker frame.
    • The electromagnet actives an electrical field that mimics the frequency and intensity sent from the amp and mixer
    • The field cause a voice coil attached to the sound cone to vibrate back and forth
    • The cone mimics the frequency and intensity of the processed electrical signal.
  19. Woofers (low)
    Tweeters (high)
    Horns and power drivers
    speaker frequency range
  20. Built in powered amps and signal processing
    Overload protection
    Out-load signal of mixer must match input level of speaker
    power speakers
  21. Split the signal into different frequencies to the different types of speakers
    cross overs
  22. Why do we need a sound console?
    • The technological advances of the late 19th century
    • Show control
  23. Prerecorded music and effects
    Electric light revolutionizes the presentation and production of theatre
    Fully lit stages
    Naturalized scenery
    Acting is moved from the forestage to behind the proscenium
    Audiences have a difficult time hearing
    technological advances
  24. Multiple microphone sources
    Playback equipment
    Multiple speakers
    show control
  25. what is a mixing console
    An electronic platform for combining, routing and changing the level, timbre and dynamics of audio signals.
  26. what can a mixing console do?
    • Designed to take audio signals
    • from a set of inputs
    • run it through a refinement process
    • send it out to a set of outputs
  27. Boost the weak outputs of microphones and playback devices to a higher level of energy
    First electronic circuit the processes signal coming from a mic or playback device
    Provides the most gain, easiest place to get distortion and feed back
    Often work with an amplifier within the microphone or playback device that gives the engineer more room to play
    Impedance converters
  28. Filters that control and process the timbre or tone of the sound being sent out to the speakers (Treble, bass and equalizers)
    eliminate unwanted sounds and combat feedback
    make certain instruments/voices more prominent or enhance particular aspects of an instrument's tone
  29. Controls the amount of input being sent to the master fader
    Pre-fade- all the sound mix happens before the final package is sent to the master
    Post-fade- mixing happens in between the input fader and post fader
  30. what are the three sections of analog sound board
    • Channel Input Strip
    • Master Control
    • Audio Level Metering
  31. nput Jacks
    Dynamic processing
    Input faders
    RCA and XLR ports
    parts of the input strip
  32. Aux-send (sends the mixed signal to another unit (effects unit) for further enhancement)
    Sub assignments
  33. provide a lot more options in a screen with routines and subroutines
    Write automated or pre-recorded cues
    Reconfigure by touching a button
    digital sound console
  34. used for 
    adjusting the pre amps
