AAERT CDR Exam Questions and Answers
cardioid
-pick up pattern
heart shaped (kardioeides)
-reaches out from diaphragm
-single voice in front
-super/ hyper more narrow areas of sensitivity
omnidirectional
-all directions
-equal from all directions
-Multiple voices , one microphone
-more speakers than available recording channels
-switches allow for pu pattern change
condenser
-capsules can also be changed to switch Pu pattern
Dynamic Microphone
-moving coil
-diaphragm, coil, magnet-
-diaphragm = flat plate @ The front of The Microphone
-Bulky
-energy-> diaphragm - > coil moves back & forth over magnet- electrical signal travels through wires
w/ in mic - > digital mixer
Condenser Microphone
-front Plate(diaphragm) , back plate & 48 v Power Source
-front & back plate = capacitor
-Assisted by electrical source
-wider assortment of shapes & sizes
- gooseneck Mic
-Low-profile boundary mic
-Lavalier Mic
-energy hits the front plate of the capacitor- > distance between plates changes - > gap is
electronically charged by phantom power
Low-profile boundary microphone
-lay flat
-inch or two thick
-lots of ambient noise & gets covered easily
Lavalier
-extremely small condenser mic &attaches directly to speaker
- no opp to place Mic in front of Speaker
- wired & wireless
Away have spare batteries
Gooseneck Microphone
-solid base & long flexible neck w/ a narrow condenser that extends towards the speaker
-toggle on and off
, XLR connectors
-the most common microphone connectors
-referred to as microphone cables
-male (3 pins) and female end(3 holes)
Digital Mixer
-device that take a signal through a cable to a computer
-referred to as audio interfaces
Mixer Input Types
-DR interested in Microphone Input
-Usually XLR Connection but can also be a TSR input
Mixer Output Types
-use either USB or FIREWIRE (IEEE 1394)
