Brooks SS 81 Harmonic Distortion

The presence of harmonics in the output signal of a device which were not present in the input signal.

Leakage
Sounds from other instruments and sources that were not intended to be picked up by the microphone.

Brooks KS-55 Format
1) The number of tracks, their width, spacing and order for tape recording.
2) To prepare a digital storage medium so that it will accept and store digital information bits.

Input/Output Module
A set of controls, on one housing, for an in-line console that has two channels (one for recording and one for monitoring) and has controls for all console sections.

Brooks QS 70 Beat
1) The steady even pulse in music.
2) The action of two sounds or audio signals mixing together and causing regular rises &.falls in volume.

Electret Mic
A condenser microphone where the capacitor plates are given a charge during manufacture which they retain, therefore requiring no external power supply.

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.

Haas Effect
Simply stated, a factor in human hearing where delay has a much bigger effect on human perception of direction than level does.
