Crossover, Passive
Used inside of full range speaker cabinets to separate highs, mids, and lows and send them to their respective speakers within the each cabinet. These are not as efficient as active crossovers because they require all frequencies to draw from the same source of amplification.

Brooks TA 60 Formant
An element in the sound of a voice or instrument that does not change frequency as different pitches are sounded.

Echo Send
The output of a console used to send a signal to an echo chamber or delay effects device.

Brooks KS-55 Line In (Input, return)
Where a signal enters the board or component.

Level
Sets output volume of individual PA input channels. Usually positioned as sliders at the bottom of the soundboard.

Boundary Mic
A microphone mounted on a flat plate that acts as a reflective surface directing sound into the mic capsule. Used for general pick-up over a large area. See PCC, PZM.

Folded Horn
A speaker design where the speaker points back into the cabinet and bounces around finally coming out large ports in the front. It is intended to maximize low frequencies in a relatively small cabinet.
