CONDENSER MIC Advantages –Small –Good frequency response –Very sensitive
32
CONDENSER MIC Advantages –Small –Good frequency response –Very sensitive Disadvantages –Needs external power to work –Sensitivity may lead to distortion
33
CONDENSER MIC Things to remember: The only mic that needs a battery or other power supply The only mic that has no magnet

54
CABLES & CONNECTORS RCA CONNECTOR UNBALANCED: –Non-professional use (home audio) –Sometimes called “phono” plug for its use with phonographs
55
CABLES & CONNECTORS UNBALANCED: PHONE PLUG Another type of unbalanced plug
56
CABLES & CONNECTORS PHONE PLUG UNBALANCED: Named for its origin as a telephone switchboard plug
57
CABLES & CONNECTORS PHONE PLUG UNBALANCED: Used to connect electric guitars and headphones
58
CABLES & CONNECTORS UNBALANCED: Don’t confuse the “phone” plug...... with the RCA “phono” plug
