Sound for Doc: Equipment – Single System
Mixer: Shure FP33Microphone: Shotgun & Lavs (lavs/wireless next
week)
Breakaway Cable
Audio Recorder - ?
Sound for Doc: Audio Signal Flow
Shotgun Mic (416) Mixer (FP33) Camera (DVX100)
Concepts (review): MIC vs LINE Levels
Level: ‘Strength’ of electricity (Voltage)
MIC levels are ?
Line levels are ?
Concepts: MIC vs LINE Levels
Level: ‘Strength’ of electricity (Voltage)
MIC levels are weak, small, low. (milliVolts). Not useful unless they are amplified.
Line levels are strong, over a hundred times stronger than MIC levels. (Volts)
MIC levels need to pass through a preamp in order to become line levels.
MIC preamp knobs on FP33

Concepts: Mixing
What is dynamic range?
If the audio is too loud/strong you may get _____.
If the audio is too low you may get _____.
One way to deal with this is by changing the input gain.
Concepts: Monitoring & MetersListening: Two places to monitor your sound from: _____
Looking: Meters on the FP33 are different than those on the 702T and DVX100. FP33 meters (analog) react much slower than 702T/camera meters (digital).
Ideal dialogue levels On FP33 meters: -10dB - +3dB Ideal levels on the
DVX100/PD150: -20dB - -8dB
Concepts: System Calibration
How do we know we’re recording clean audio to the camera since we can’t see the camera’s meters?
Send Line Up tone:
0 VU = -20 dBFS
Monitoring Sound from Camera
Plug small end (1/8”) of breakaway cable into headphone jack in camera.
Plug other mini jack into MON IN in FP33. Switch to MON on front of FP33.
Sound for Doc: Boom Op
1. Know the frame line. Boom from above when possible.
2. Get mic close as possible to sound source while staying out of frame line.
3. Be VERY aware of the umbilical cord (breakaway cable).
In-Class ExerciseOne talking subject.Static shot: Record examples of levels that are
1. too high 2. too low 3. just right
Verabally slate what you’re doing (can use slate mic).
Moving shot: subject- change place - . Know your frame line.
