SOUND and AUDIO
• SOUND is the physical vibration of molecules in the air
SOUND and AUDIO
• SOUND is the physical vibration of molecules in the air
• AUDIO is the electrical representation of sound
MICROPHONES
• A microphone is a TRANSDUCER
MICROPHONES
• A microphone is a TRANSDUCER
• A transducer converts one form of energy to another
MICROPHONES
• A microphone is a TRANSDUCER
• A transducer converts one form of energy to another
• Microphones convert SOUND energy into ELECTRICAL energy
MICROPHONES
THREE TYPES OF MICROPHONES:
– Dynamic

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

CABLES & CONNECTORS
TWO TYPES OF CABLES:
CABLES & CONNECTORS
TWO TYPES OF CABLES:
– Balanced
CABLES & CONNECTORS
TWO TYPES OF CABLES:
– Balanced
– Unbalanced
CABLES & CONNECTORS
BALANCED:
– Has 3 wires
CABLES & CONNECTORS
BALANCED:
– Has 3 wires: 2 conductors plus shield
CABLES & CONNECTORS
BALANCED:
– Has 3 wires: 2 conductors plus shield
XLR CONNECTORS
CABLES & CONNECTORS
BALANCED:
– 3 wire design rejects noise
XLR CONNECTORS
CABLES & CONNECTORS
BALANCED:
– Used in professional situations
XLR CONNECTORS
CABLES & CONNECTORS
UNBALANCED:
– Has 2 wires
CABLES & CONNECTORS
UNBALANCED:
– Has 2 wires
CABLES & CONNECTORS
UNBALANCED:
– Has 2 wires
RCA CONNECTOR
CABLES & CONNECTORS
UNBALANCED:
– Susceptible to noise
RCA CONNECTOR
CABLES & CONNECTORS
RCA CONNECTOR
UNBALANCED:– Non-professional use (home audio)– Sometimes called “phono” plug for its use with
phonographs
CABLES & CONNECTORS
UNBALANCED:
PHONE PLUG
Another type of unbalanced plug
CABLES & CONNECTORS
PHONE PLUG
UNBALANCED:Named for its origin as a telephone switchboard plug
CABLES & CONNECTORS
PHONE PLUG
UNBALANCED:
Used to connect electric
guitars and headphones
CABLES & CONNECTORSUNBALANCED:
Don’t confuse the “phone” plug . . .
. . . with the RCA
“phono” plug
