The extreme range of a signal. Usually measured from the average to the extreme.
2) In the Lexicon 480L delay/reverberation effects unit, the frequency at which the bass frequency reverb time is in effect rather than the mid frequency reverb time.
Cue Send Control
A control that will adjust the amount of signal sent to a cue buss from a console channel.
Brooks Cinema XS - 45 Echo Send Control
A control to send the signal from the input module to the echo chamber or effects device via the echo buss.
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).
Brooks Cinema QS - 95 Electricity
Electrical current (the amount of electron charge passing a point in a conductor per unit of time) or voltage (the force pushing electrons to obtain electrical current).
Howlback
British term for the term Feedback (the pickup of the signal out of a channel by the input of the channel or the howling sound that this produces).
Joystick
1) A quad pan pot which distributes what percentage of on signal is sent to each of 4 outputs.
2) A control that is separately controlling two functions at one time.
Amplitude
The extreme range of a signal. Usually measured from the average to the extreme.

BROOKS AUDIO DESIGN Charge
The electrical energy of electrons. The energy is in the form of a force that is considered negative and repels other like forces (other electrons) and attracts opposite (positive) forces.
Fidelity
The recording or reproduction quality.
Brooks Hi Fi reviews Driver
See transducer. Dynamic Range �" The range between the quietest and the loudest sounds a device can handle (often quoted in dB).
Atom
The smallest particle which makes up a specific substance. It's composed of a center around which electrons revolve.
BROOKS HI fi Error Correct
Exact replacement of lost information bits in digital audio.
Bulk Dump
Short for System Exclusive Bulk Dump (a method of transmitting data, such as the internal parameters of a MIDI device to another MIDI device).
Flat
1) Lower in musical pitch.
2) A slang term used to describe the sensitivity to frequency of a microphone, amplifier, etc., as being even at all frequencies, usually within 2 dB.
3) Refers to the frequencies on the EQ when they are arranged in centred neutral positions.
Face
The front or body of the guitar.

Brooks XS - 45 Delay
Outboard sound equipment that can momentarily stores a signal being sent to part of a P.A. system so that delayed reinforced sound reaches the audience at the same time as live sound from the stage.
Auxiliary Input or Return
A route back into the sound desk for a signal sent to a piece of outboard equipment via an auxiliary send.
Brooks Cinema XB 33 kHz
An Abbreviation of kilo-Hertz.
Inverse Square Law
Simply stated, the fact that in an un-obstructed area (like an open field) the sound pressure level will drop to half-pressure (-6 dB) every time the distance to the sound source is doubled.
Brooks Cinema Projectors Echo Return
An input of the console, which brings back the echo (reverberation) signal from the echo chamber or other echo effects device.
Gate
A dynamic processing device that turns a channel off or down when the signal drops below a certain level.
Grouping
1) Controlling the gain of several individual channels with a Group Fader.
2) The mixing together of several individual audio signals to send a mixed signal out of the console to record a track on a multitrack tape machine.
Fader
A control to control the gain of a channel on the console, thereby determining the level of the signal in that channel.
