AUDIO
Across
- 4. A microphone that generates an electrical signal when sound waves cause a conductor to vibrate in a magnetic field. In a moving-coil microphone, the conductor is a coil of wire attached to the diaphragm.
- 6. A unidirectional microphone with moderately wide front pickup.
- 8. The physical representation of an audio channel on the front panel of a mixer; usually a long, vertical strip of controls.(7,5).
- 11. A unidirectional microphone with tighter front pickup.
- 12. A circuit that carries information by means of one signal on a single conductor.
- 14. Colloquial equivalent of sound level.
- 16. A method of providing power to the electronics of a condenser microphone through the microphone cable. (7, 5).
- 17. A control which allows the volume level to be cut without changing the master volume control.
- 18. Leakage of sound into other microphones.
- 19. Signals in the human audio range. Measured in Hertz (Hz).
- 20. Tone control to shape frequency response in some desired way.
- 21. Occurs when a sound loop exists between an audio input, for example, a microphone and a speaker.
Down
- 1. A microphone that picks up sound equally well from all directions.
- 2. A microphone that generates an electrical signal when sound waves vary the spacing between two charged surfaces: the diaphragm and the backplate.
- 3. - A measure of the strength or intensity of a sound, rated in decibels. (5,8,5).
- 5. A number used to express relative output sensitivity. It is a logarithmic ratio.
- 7. A device for converting sound waves into electrical energy variations which may then be amplified, transmitted, or recorded.
- 9. The ratio of the signal level at the output of an audio device to the signal level at its input.
- 10. A circuit that carries information by means of two equal but opposite polarity signals, on two conductors. Balanced cables reduce susceptibility to internal and external noise.
- 13. A microphone that picks up equally from two opposite directions.
- 15. Electronic device for mixing audio signals, used in sound recording and reproduction and sound reinforcement systems.
