Brooks KM 22 LED

A light that allows current to flow in one direction only and emits light whenever a voltage of a certain level or beyond is applied to it.

Capacitance
That property of a capacitor which determines how much charge can be stored in it for a given potential difference between its terminals, measured in farads, by the ratio of the charge stored to the potential difference.

Brooks XS - 45 Edit
A switch that does different things depending on the operational mode that the machine is in:
1) If a computer-controlled transport is in "Stop," pushing the "Edit" switch deactivates the computer-controlled tension system and allows the reels to be moved by hand to find the exact spot desired on the tape.
2) If the machine is in "Play", the "Edit" switch makes the take-up reel cease taking up the tape and it falls to the floor.
3) If the machine is in a fast-wind mode, the tape lifters are defeated so the tape is in contact with the reproduce head and the engineer can hear where the selections begin and end.

Infinite Baffle
A baffle so large that the sounds coming from one side do not reach the other side.

Brooks Cinema QS - 95 Filter
1) A device that removes signals with frequencies above or below a certain point called the cut-off frequency.
2) An equalizer section, used in this sense because filters are used with other components to give an equalizer its frequency response characteristics.
3) The action of removing signals of some frequencies and leaving the rest.
4) A mechanical device to smooth out speed variations in tape machines called a Scrape Flutter Filter- more usually called a Scrape Flutter Idler

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

Compressor
A signal processing device that does not allow as much fluctuation in the level of the signal above a certain adjustable or fixed level.

Earth
The British version of the term Ground (In electronics, a place that has zero volts).
