EQ
The name of the EQ that cuts low frequencies.
Low Cut/High Pass Filter
A loudspeaker component designed to reproduce very low bass frequencies.
Subwoofer
The final audible sound produced by a device, like a speaker or headphones, after processing an audio signal.
Output
Vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.
Sound

Audio Snake
The letter that represents making a bell EQ wider or narrower.
Q
A device that combines multiple audio sources, converts audio into digital data (0s and 1s) for manipulation.
Digital Sound Board (DMC)
The source of an audio signal, like a microphone or instrument, which is being fed into a recording device.
Input
The part of the sound spectrum audible to humans, generally held to range from around 20Hz-20kHz.
Audio Frequency
Relative levels of the left and right channels of a stereo recording. Also describes the relative levels of instruments and voices within a mix.
Balance
The EQ that gradually fades to a plateau.
Shelf EQ
A balanced cable that has three pins and sends signal from a microphone to a sound board.
XLR Cable
Audio that is recorded and played back through a single audio channel.
Mono

Equalizer
A microphone that is equally sensitive in all directions.
Omni

Fader
Indication of how many cycles of a repetitive waveform occur in the space of one second. A waveform which has a repetition cycle of once per second has a frequency of 1Hz.
Frequency
Severe form of distortion which occurs when a signal tries to exceed the highest level which a piece of equipment can handle.
Clipping
Draw a bell EQ.
Bell EQ
A device that uses analog sound transmission, or continuous electrical voltage to represent sound, maintaining a pure, natural signal path to adjust the volume and tone of audio signals.
Analog Sound Board
Common electrical signal path along which signals may travel. In a mixer, there are many several ______ carrying the stereo mix, the groups, etc.
Buss
A unit used to measure the intensity of sound, essentially how loud a sound is.
The safety margin in decibels between the highest peak signal being passed by a piece of equipment and the absolute maximum level the equipment can handle.
