definition test #3 Name: ____________________________________ Fader 1. A microphone whose diaphragm consists of a condenser plate that vibrates with the sound pressure against another fixed condenser plate, called the backplate. Condenser Microphone 2. A room adjacent to the studio in which the director, the technical director, the audio engineer perform their various production functions. Control Room 3. A microphone whose sound pickup device consists of a diaphragm that is attached to Fade a movable coil. As the diaphragm vibrates with the air pressure from the sound, the coil moves within a magnetic field, generating an electric current. Dynamic Microphone 4. The gradual appearance of a picture from black or its disappearance to black Feed 5. A sound-volume control that works by means of a button sliding horizontally along a specific scale. Freeze-frame 6. Signal transmission from one program source to another. Impedance 7. Piercing squeal from the loudspeaker, caused by the accidental reentry of the Transformer loudspeaker sound into the microphone and subsequent over amplification of sound. Floodlight 8. The portion of a scene visible through a particular lens. Feedback 9. Additional light on the opposite side of the camera from the key light to illuminate shadow areas and thereby reduce fall off. Usually done with floodlights. Hue 10. Lighting instrument that produces diffused light with a relatively undefined beam Frame edge. Impedance 11. The smallest picture unit in film, a single picture. 30 per second. Generation 12. Continuous replaying of a single frame. Field of View 13. level of amplification for audio signals. Fill Light 14. The number of dubs away from the original recording. Gain 15. The space left between the top of the head and the upper screen edge. Headroom 16. One of the three basic color attributes; it is the color itself—red, green, blue, yellow, and so on. Intercom 17. Type of resistance to the signal flow. Knee Shot 18. Device allowing a high-impedance mic to feed a low-impedance recorder or vice versa. Jump Cut 19. Used by all production and technical personnel for communication. Jogging 20. Frame-by-frame advancement of videotape with a VTR. 21. Cutting between shots that are identical in subject, yet slightly different in screen location. The subject seems to jump from one screen location to another for no apparent reason. 22. Framing of a person from approximately the knees up.
