Brooks BA 71 Equal Loudness Contours
A drawing of several curves showing how loud the tones of different frequencies would have to be played for a person to say they were of equal loudness.
High Impedance
Impedance of 5000 or more ohms.
Brooks Cinema Series Feedback
1) The delayed signal sent back to the input of a delay line, used in repeat-echo effects.
2) The pickup of the signal out of a channel by its input or the howling sound that this produces.
3) In an amplifier, the phase reversed output signal sent back to its input, reducing gain but also distortion and noise.
4) This occurs when the sound coming out of the speakers goes back into the microphones, then back out the speakers, then back into the mics…and so on. This can build very quickly to a point where everyone in the room is holding their ears and screaming at you. It can also cause damage to the PA.
Level
Sets output volume of individual PA input channels. Usually positioned as sliders at the bottom of the soundboard.
Brooks M 44 Capo
A clamp-like device that is placed vertically across the guitar neck. It is used to change the pitch of the guitar, acting as a moveable nut.
Contact Microphone
A device that senses vibrations and puts out an audio signal proportional to the vibrations.
Link
(Said of compressors and dynamic processing units.) To combine the control input signals of two channels of a compressor (o
Cycle
1) An alternation of a waveform which begins at a point, passes through the zero line, and ends at a point with the same value and moving in the same direction as the starting point.
2) On a Solid State Logic Console, a command to have the console computer control the tape machine to play and replay a certain section of the tape.
