Microphone Techniques Chao-Chih Huang 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 Microphone Techniques Polar Pattern • Omnidirectional • Cardioid • Supercardioid • Hypercardioid • Bidirectional(Figure-eight) QuickTime™ and a TIF F (Uncompressed) decompressor are needed to see this picture. Advancing the Power of Sound QuickTime™ and a TIF F (Uncompressed) decompressor are needed to see this picture. Microphone Techniques Types of different Mic • • • Hand-held Mic Quic kTime™ and a TIFF (Unc ompres sed) dec ompres sor are needed to see this pic ture. QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture. Head-set Mic Clip-on Mic Quic kTime™ and a TIFF (Unc ompres sed) dec ompres sor are needed to see this pic ture. Advancing the Power of Sound 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 QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture.

Advancing the Power of Sound Microphone Techniques The Clothes of Mic • • • Wind screen (thin/thick sponge cap) Pop-filter Hairy cover (provides maximum protection against wind noise ) QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture.

Advancing the Power of Sound MicrophoneaTechniques • 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 MicrophoneaTechniques 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 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 Microphone Techniques Rehearse with your maximum and minimum voice Let the engineer knows your volume range • Prevent distortion • Make sure the recording level is enough • Balance with the music Advancing the Power of Sound Microphone Techniques Don't just stand there... • Listen to your sound from the monitors on-stage monitors FOH (Front of house) monitors Control room monitors (Recorded sound) • Adjust the way you sing if appropriate • Suggest to your engineer Louder... please... To use some effects Advancing the Power of Sound Microphone Techniques DURING THE SHOW/RECORDING Please don't eat the mic! • The more loud, the more distance needed • Pull away the mic on high, loud notes The location of mic • Minimum distance: under bottom lip • Advantage: avoid the popping effect by some certain consonants (b; p; t) Advancing the Power of Sound 數位非線性錄音系統 Microphone Techniques Don't cup hands over the head of the mic • Muffle the voice Let engineers control the switch of mic • Don't use the switch on the mic even there is one Professional mic switch design • Boom sound • Communicate with your engineer, when to... • Trust your engineer Advancing the Power of Sound 數位非線性錄音系統 Microphone Techniques Don't sing around the monitors! • Feedback High pitched QuickTime™ and a TIFF (Uncompressed) decompressor noise are needed to see this picture. • • Pre-test the feedback frequency Use EQ to dampen the feedback Advancing the Power of Sound 數位非線性錄音系統 Microphone Techniques Make sure your voice is heard by yourself • In on-stage monitors (Live) • In headphones (Studio) Live concert, audiences enter arena... You won't sing uphill Easy for you to control your voice Cue your engineer Advancing the Power of Sound 數位非線性錄音系統 Microphone Techniques AFTER THE SHOW/RECORDING Don't kill the mic and all other equipment Don't just TRUN/PULL OFF mic! Condenser mic phantom power Dynamic mic Boom sound Advancing the Power of Sound 數位非線性錄音系統 Microphone Techniques Shutting down the system • Power amp • Effects • Mixer/ Phantom power • Disconnect mic Mic storage • Temperature control • Humidity control Advancing the Power of Sound 數位非線性錄音系統 Microphone Techniques a dna ™emiTkciuQ rosserpmoced )desserpmocnU( F FIT .erutcip siht ees ot dedeen era AKG C414 B-TL II a dna ™emiTkciuQ rosserpmoced )desserpmocnU( FFIT .erutcip siht ees ot dedeen era Neumann U87 Ai QuickTime™ and a TIFF (Uncompressed) decompressor are needed to see this picture.
