Training

frequency
Frequency
  • Frequency determines the pitch of a sound
  • Higher frequencies make higher notes
  • Frequency is measured in Hertz (Hz) or cycles per second
  • Common Frequency Bands:
  • Low: 20 Hz – 250 Hz center: 100 Hz
  • Mid: 250 Hz – 5 kHz center: 1 kHz
  • High: 5 kHz – 20 kHz center: 10 kHz
amplitude
Amplitude
  • Amplitude determines the volume or intensity of a sound wave
  • Sound intensity is measured in decibels (dB)
  • dB is a measurement relative to a reference sound level
  • A 10 dB sound is 10 times the intensity of the reference level
  • A 20 dB sound is 100 times the intensity of the reference level
  • A 30 dB sound is 1000 times the intensity of the reference level
  • A 0 dB sound has the same intensity as the reference level
input sources
Input Sources

Microphones

  • Types – dynamic, condenser
  • Patterns – omnidirectional, cardioid, supercardioid

Instruments

  • Guitar, piano, bass, drums

Other

  • CD player, iPod, computer

omnidirectional

supercardioid

cardioid

mixing console
Mixing Console
  • Mixes, tunes, and controls the destination and volume of audio signals
  • Combines input signals to form outputs for main and monitor speakers
power amplifier
Power Amplifier
  • Take signals and amplify them so they can drive speakers
  • Power of an amplifier is measured in Watts
  • Make sure that the amplifier matches the impedance of the speakers being used
  • Watch for clipping or distortion

Clipping

speakers
Speakers

Main Speakers

  • Provide sound for audience

Monitor Speakers

  • Provide sound for musicians on stage
  • Speakers are rated in terms of impedance. Common values are 2 Ohms, 4 Ohms, and 8 Ohms
cables and connectors

XLR

1/8” (mini-plug)

RCA

1/4”

Cables and Connectors
  • Connect all the different components of the sound system

Types of Cables

  • Unbalanced – Short cables connecting instruments to amps/snake
  • Balanced – Longer cables carrying line-level signals to and from mixer
  • Unshielded – Thicker cables carrying amplified signals from amp to speakers
