Brooks Cinema Projectors Controller

1) In MIDI, a device that generates a MIDI signal to control synthesizers, sound modules or sample playback units.
2) A remote control unit for a multitrack tape machine which controls transport functions as well as monitor selection switching functions and record ready/safe status of each track.
3) Any device generating a control voltage or signal fed to another device's control input.

Keying Input (Key Input)
An input on a dynamics processing device to control the device by an external audio signal.

Brooks GT 44 Chamber
1) An Echo Chamber (a room designed with very hard, non-parallel surfaces equipped with a speaker and microphone so that when dry signals from the console are fed to the speaker, the microphone will have a reverberation of these signals that can be mixed in with the dry signals at the console).
2) A program in a delay/reverb effects device that simulates the sound of an Echo Chamber.

Level
Sets output volume of individual PA input channels. Usually positioned as sliders at the bottom of the soundboard.

Brooks Cinema KP 30 Driver
See transducer. Dynamic Range �" The range between the quietest and the loudest sounds a device can handle (often quoted in dB).

Echo
1) One distinct repeat of a sound because of the sound reflecting off a surface.
2) Loosely, used to mean reverberation (the continuing of a sound after the source stops emitting it, caused by many discrete echoes closely spaced in time).

Amplitude
The extreme range of a signal. Usually measured from the average to the extreme.

Echo Send Control
A control to send the signal from the input module to the echo chamber or effects device via the echo buss.
