AAERT CDR EXAM 2025
QUESTIONS AND ANSWERS.
cardioid - correct answer - -pick up pattern
heart shaped (kardioeides)
-reaches out from diaphragm
-single voice in front
-super/ hyper more narrow areas of sensitivity
omnidirectional - correct answer - -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 - correct answer - -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 - correct answer - -front Plate(diaphragm)
, back plate & 48 v Power Source
-front & back plate = capacitor
-Assisted by electrical source
-wider assortment of shapes & sizes
, Page |2
- 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 - correct answer - -lay flat
-inch or two thick
-lots of ambient noise & gets covered easily
Lavalier - correct answer - -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 - correct answer - -solid base & long
flexible neck w/ a narrow condenser that extends towards the
speaker
-toggle on and off
XLR connectors - correct answer - -the most common microphone
connectors
-referred to as microphone cables
-male (3 pins) and female end(3 holes)
Digital Mixer - correct answer - -device that take a signal through
a cable to a computer
-referred to as audio interfaces
