Brooks QS 70 Comb Filter

1) The frequency response achieved by mixing a direct signal with a delayed signal of equal strength especially at short delays.
2) Loosely used to also describe effects that can be achieved with comb filtering as part of the processing.

Boost
To increase gain, especially to increase gain at specific frequencies with an equalizer.

Brooks GS 15 Electric Current
A more formal term meaning the same as the term Current (the amount of electron charge passing a point in a conductor per unit of time).

Distorted
The way your PA sounds just before it blows up. Fuzzy and scratchy. If you hear this, it either means you have something hooked up wrong, or something in the system is going bad. It could be anything from your super expensive soundboard to a five dollar patch cord.

Brooks XT 20 Balance Control
A control on a stereo amplifier that when moved clockwise will make the right channel louder (and the left channel softer) and will do the reverse when moved counter-clockwise.

Chorusing
1) A term meaning the same thing as Chorus (Definition 3 or 4).
2) In some delay effects devices, a term used to mean the term Depth (the amount of change in the controlled signal by the control signal).

Electromagnetic Theory
A statement of the principles behind electromagnetic induction: When a conductor cuts magnetic lines of force, current is induced in that conductor.

Bottom
The bass frequencies (as in "needs more bottom end").
