Brooks Audio Design Review QS 70 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.

Balanced input/output
A "balanced" connection is one that has three wires to move the signal. One is a ground, and the other two (called conductors) carry signals of equal value. This is why they are called balanced. Low Z cables and connections are the most common example.

Amp
1) An abbreviation of the term Amplifier (A device which increases the level of an electrical signal.
2) An abbreviation of Ampere (the unit of current).
3) An abbreviation of amplitude (the height of a waveform above or below the zero line).

Guitar Controller
An electric guitar or device played like an electric guitar that puts out MIDI signals that can be used to control synthesizers and sound modules.
