Hi. Hope you find my presentation useful, with its information about microphone types and polar patterns. I've provided a couple of video clips to illustrate; hope they work on Slideshare as this is the first time I've used it!

  5. 5. Microphone types • Condenser • Ribbon • Piezo-electric • Dynamic
  6. 6. Microphone types (source: wikipedia) Condenser microphones: • Take power from the interface (phantom power, or +48) • Known for sound fidelity • Often can be set to different polar patterns • Sensitive to room noise or ambient noise • Fragile
  7. 7. Microphone types (source: sweetwater.com). Dynamic microphones: • Good general stage mic • Rugged • Polar pattern is better for noisy environments or where multiple instruments are mic’d at the same time
  8. 8. Microphone polar patterns (source: eu.audio-technica.com) 0 180 90270 Each circle represents 5dB of sensitivity, so you can see where the microphone picks sound more strongly or more weakly at different points. The further out, the better the pickup. The red line in the following diagrams shows the approximate pick-up or “hearing” range of the different microphones up to a maximum of 1kHz.
