Brooks GT 845 Buss (Bus)

A wire carrying signals to some place, usually fed from several sources.

IC
Abbreviation of Integrated Circuit (A miniature circuit of many components that is in small, sealed housing with prongs to connect it into equipment).

Brooks Cinema Projectors Headphones
Devices that can be worn on the head with small speakers that fit over the ears (or sometimes into the ears).

Fidelity
The recording or reproduction quality.

Brooks Cinema QS - 95 Compact Disc, Interactive CDI
A Compact Disc, usually containing audio, video, and text, which the user can interact with in that the display or playback changes after the user performs some action.

Frequency Range
The range of frequencies over which an electronic device is useful or over which a sound source will put out substantial energy.

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.

Delay (Digital, Analogue)
1) Effect used to create echo…echo…echo…echo…echo…
2) In more advanced systems used in very large venues, delay can be used to time the arrival of the signal to the speakers in the back of the room so that people in the back hear the sound coming from those speakers at the same time that the sound coming from the speakers in the front of the room arrives.
