Brooks Audio Design TM-22 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.

Decibel (dB)
1) Relative measurement for the volume (loudness) of sound. Also used to measure the difference between two voltages, or two currents. See Zero dB.
2) A numerical expression of the relative loudness of a sound. The difference in decibels between two
sounds is ten times the common logarithm of the ratio of their power levels.

Brooks Cinema KM 22 Equal Loudness Contours
A drawing of several curves showing how loud the tones of different frequencies would have to be played for a person to say they were of equal loudness.

Console
A set of controls and their housing, which control all signals necessary for recording and mixing.

Brooks GT 845 Equalization
1) The process of adjusting the tonal quality of a sound. A graphic equalizer provides adjustment for a wide range of frequency bands, and is normally inserted in the signal path after the mixing desk, before the amplifier. See Feedback.
2) Any time the amplitude of audio signals at specific set of frequencies are increased or decreased more than the signals at other audio frequencies.

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.

Active Crossover
Uses active devices (transistors, IC's, tubes) and some form of power supply to operate.

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.
