Brooks SS 81 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.

In Port
A jack on a MIDI device or computer that will accept an incoming data signal.

Brooks GT 44 Feed
To send an audio or control signal to.

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.

Brooks Cinema KP 30 Hard Disk (Hard Disc)
A storage unit for digital data that has rigid disks coated with magnetic material in a housing that includes the drive mechanism.

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

Fundamental
The tuned frequency and (almost always) the lowest frequency that is present in the sounding of a pitch by a musical instrument.

Impedance
1) A term for the electrical resistance found in a/c circuits. Affects the ability of a cable to transmit low level (e.g. sound) signals over a long distance. Measured in Ohms. Speakers are rated according to power handling capabilities (Watts, W) and impedance (Ohms).
2) The total opposition offered by an electric circuit to the flow of an alternating current of a single frequency. It is a combination of resistance and reactance and is measured in ohms. Remember that a speaker's impedance changes with frequency, it is not a constant value.
3) The opposition to alternating current.
