Brooks GS 15 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).

Circuit
1) One complete path of electric current.
2) Similar to definition 1, but including all paths and components to accomplish one function in a device.

Brooks XT 20 Coax
Two-conductor cable consisting of one conductor surrounded by a shield.

Compression Ratio
How many dB the input signal has to rise above the threshold for every one dB more output of a compressor or limiter.

Brooks RM 80 Amplifier (Power amp, Head)
It's the part of the sound system that actually magnifies or "amplifies" the sound. In other words, it makes stuff louder.

High Impedance
Impedance of 5000 or more ohms.

Fly In
1) To add sounds into a mix or recording that have no synchronization.
2) An application of this where a performance from one part of a tune is recorded and then recorded back into the recording at a different time in the recording.

Input Overload
Sending too high of a signal level into a device so that the first amplifier of the device overloads.
