What is a Trough, and what is it also referred to as?
The lowest point of a sound wave; rarefaction
Define the term ‘Rarefaction’.
When the vibrating object moves inward, pulling the molecules farther apart; thinning them.
Define the term ‘Amplitude’.
How many molecules are set in motion by the vibrating body.
Define the term ‘Phase’.
The time relationship between two or more sound waves in their cycle.
What is Phase Cancellation?
Occurs when two sound waves are 180 degrees out of phase.
What is ADSR?
Attack
Decay
Sustain
Release
Define the term ‘Attack’.
The initial start of a sound.
Define the term ‘Decay’.
The softening after the attack.
Define the term ‘Sustain’.
The period that the sounds volume is maintained.
Define the term ‘Release’.
The time where the sound fades into silence.

What is Direct Sound?
When sound reaches the listener directly, without hitting any objects.
What is Indirect Sound?

What is a Dynamic Microphone?
Uses Electro Magnetic Induction to create an output signal.
What is a Condenser Microphone?
Uses Electrostatic principle; contains a capsule made up of two thin plates.
Define the terms ‘Phantom Power’.
48 Volts; supplied by console or preamp.
What is an Omnidirectional Microphone?
A microphone that picks up sound equally from all sides.
What is a Bi-Directional Polar Pattern?
Picks up sound from the front and back of the mic; rejects from the sides.
What is a Cardoid Polar Pattern?
Picks up sound from the front, and a little from the sides; rejects from the back.
What is a Uni-Directional Polar Pattern?
Picks up sound from only the front of the mic.
Define ‘Frequency Response’.
How microphones receive various frequencies, and at what levels.
Define the term ‘Max SPL’(Sound Pressure Level).
The level in which the microphone’s output signal begins to distort.
What is Proximity Effect?
When microphones are placed close to a sound source, bass frequencies increase.
What is a Parabolic Microphone?
A long distance pickup mic; used outdoors at sporting events.
What is a Shock Mount?
Helps to reduce vibrations from the floor or mic stand.
What does the Console Input Section contain?
EQ Phantom Power Preamp Volume Fader Pan Knob Aux Send
Describe the Inputs section.
XLR - Mic
Quarter Inch - Instruments
Quarter Inch - Inserts
What is the ‘Insert’ section used for?
A quarter inch insert for a y cable; used to route the output of that channel into a compressor, and then back to the channel.
What is ‘Aux Sends’ used for?
Used for time based effects, or monitored mixes (live instruments).
What is the ‘Pre’ Button used for?
When engaged, the level sent to the Aux is controlled by the Aux Send, and will not be affected by the Main Volume Fader.
What are Busses/Subgroups?
Routes channels to outputs; 98% of the time, the Bus relates to the channels on the MTR.
Describe the Output Section.
Contains Master Faders for all outputs; Routes signal from input section to MTR.
Describe the Monitor Section.
Controls what is heard through the speakers and the headphones; also contains the ‘Talk Back Mic’.
Define the term ‘DAW’.
Digital Audio Workstation; Protools, Logic
Define the term ‘MTR’.
Multi Track Recorder
