  2. Microphone Techniques INTRODUCTION TO MICROPHONES Diaphragm • Dynamic Mic: Moving Coil and Ribbon Mic • Condenser Mic/ Capacitor Mic phantom power: 9~52 V, usually 48 V * Can NOT tell from the looks, you have to read the manuals! Advancing the Power of Sound

  3. Microphone Techniques Polar Pattern • Omnidirectional • Cardioid • Supercardioid • Hypercardioid • Bidirectional(Figure-eight) Advancing the Power of Sound

  4. Microphone Techniques Types of different Mic • Hand-held Mic • Head-set Mic • Clip-on Mic Advancing the Power of Sound

  5. Microphone Techniques Wireless Mic: • UHF band(Ultra High Frequency 600-1000 MHz) • VHF band(Very High Frequency 160-250 MHz) Be sure to check the batteries Wired Mic Advancing the Power of Sound

  6. Microphone Techniques The Clothes of Mic • Wind screen (thin/thick sponge cap) • Pop-filter • Hairy cover (provides maximum protection against wind noise ) Advancing the Power of Sound

  7. a Microphone Techniques • Wind-proof purpose • Health reasons • Easy to tell in live concert by colour The more expansive, the better? • Good and expansive Dynamic Mic • Bad and cheap Condenser Mic Advancing the Power of Sound

  8. a Microphone Techniques BEFORE THE SHOW/RECORDING Choosing the right mic • By the engineers • By yourself Starting up… • Mic -> Connect the lead at the mic end -> • Connect the lead at the mixer end -> • Effects -> Power amp *** Boom problem!!! Advancing the Power of Sound

  9. Microphone Techniques Test the mic... • JUST say something, like "test… test... one… two..." NEVER DO THESE! • Blow at mic Destroy the part. Humidity influence • Pop the mic Destroy the part. Unpleasant noise Advancing the Power of Sound
