  1. Radio Production • Sound Waves • Microphone Types • Microphone Pickup Patterns • Cables & Connectors

  2. Sound is Waves! • Amplitude (Db) is the loudness of the wave • AM (Amplitude Modulation) changes the height of the wave. • Frequency (Hz) is the pitch of the sound. • FM (Frequency Modulation) changes the cycles/second of the wave.

  3. Microphone Types- Moving Coil • Sturdy and Reliable • Poor Frequency Response • Works with Electro- Magnetic Energy • Dynamic Microphone

  4. Microphone Types- Ribbon • Very Delicate • Good Response, Warm Sound • Works with Electro- Magnetic Energy • Dynamic Microphone

  5. Microphone Types- Condenser • Needs External Power • Excellent Response • Sometimes too Sensitive • Stores Electrical Charge- Capacitor

  6. Microphone Pickup Patterns • Cardioid • Super-Cardioid • Omni-Directional • Bi-Directional

  7. Handheld Shotgun Lavaliere Studio Wireless Parabolic Reflector Microphone- Physical Types

  8. Microphone Connectors

  9. Cable Handling Tips • Make sure you have more than you need • Don’t step on or crimp the cable. • Coil the cable properly to protect it!

  10. Radio Production-The Studio • Audio Console • Components • Equipment Handling

  11. The Console- The Nerve Center • - V.U. Meter • - Channel Selector • - Slider Potentiometer • - Remote/On Button • - Off Button • - Cue Channel Light • - Input Selector

  12. Studio Components • CD Players • Mini-Disc Recorder • Cassette Recorder • Reel to Reel Player/Recorder • Cart Machine

  13. Reel to Reel Machine
