5. Sound 2 types VU Meters:

6. Sound Frequency relates to the basic pitch of a sound Frequency is measured in Hertz (Hz)

7. Sound Graphic Equalizer allows specific bands of frequencies to be individually adjusted for loudness.

8. Sound Sound is affected by acoustics

9. Sound 3 types: dialog sound effects music

10. Sound Sound is captured by a device called the microphone or mic

11. Sound 6 basic types: hand held lavaliere / clip-on mic shotgun boundary effect microphone contact mics studio microphones

12. Sound Directional capabilities omnidirectional bi-directional unidirectional

13. Sound Dynamic microphones Condenser microphones

14. Sound Dynamic Mic Advantages Condenser Mic Advantages RuggedMore Sensitive Lower CostBetter Audio Quality No Power Required Need Power Dynamic Disadvantages Condenser Disadvantages Lower Sensitivity & Power Output Higher self- noise Larger and Heavier More Fragile Slower Response Time More Expensive Not the Best Choice for Prone to Weather Maximum Audio Quality Problems, RF Interference

15. Sound Mic’s - cables - patch bay - sound board

16. Sound Positioning mic’s near the heart away from jewelry rubbing against clothing hiding the cord strain relief

17. Sound Wireless mic’s no wires dead areas interference

18. Sound Wireless mic’s UHF vs VHF Multiple mic’s
