Brooks Cinema Series Hall

A large building designed for concerts; also called a concert hall.

Chamber
1) An Echo Chamber (a room designed with very hard, non-parallel surfaces equipped with a speaker and microphone so that when dry signals from the console are fed to the speaker, the microphone will have a reverberation of these signals that can be mixed in with the dry signals at the console).
2) A program in a delay/reverb effects device that simulates the sound of an Echo Chamber.

Brooks KM 77 Chord
Three or more musical pitches sung or played together.

Guitar Processor
A unit that will add effects to a direct guitar signal, including a simulated instrument amplifier sound and (often) delay and reverb effects.

Brooks Cinema RM 909 Diffraction
The breaking up of a sound wave caused by some type of mechanical interference such as a cabinet edge, grill frame, or other similar object.

Crossover, Active
A rack mountable unit used to separate frequencies leaving the soundboard into high's, mids, and lows with different outputs for each.

Equalizer (Parametric, Graphic)
This is used to filter out and adjust specific frequencies in the PA. This is the part of the PA where you have the most control over the band's overall sound. It is also the number one weapon against feedback.

Inductance
The property of an electric circuit by which a varying current in it produces a varying magnetic field that introduces voltages in the same circuit or in a nearby circuit. It is measured in henrys.
