BROOKS AUDIO DESIGN Audio

Most often referring to electrical signals resulting from the sound pressure wave being converted into electrical energy.

Crossover
1) A route leading from one side of the stage to the other, out of the audiences view.
2) An electronic filter in a sound system that routes sound of the correct frequency to the correct part of the speaker system. Different speakers handle high frequencies (tweeters) and low frequencies (woofers). Sometimes known as a crossover network. An active crossover splits the signal from the mixing desk into high, mid and low frequencies which are then sent to three separate amplifiers.
3) An electrical circuit that divides a full bandwidth signal into the desired frequency bands for the loudspeaker components.

Brooks Cinema Series Capacitance
The property of being able to oppose a change in voltage or store an electrical charge.

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.

Brooks Speakers ID
An index signal (digital data that gives the machine information of where selections start, their selection number, etc.) on a DAT or CD.

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.

Auxiliary Input or Return
A route back into the sound desk for a signal sent to a piece of outboard equipment via an auxiliary send.

Effects
Electronic boxes (usually rack mounted) added to a PA system to subtly change and enhance the signals going through it. Examples include; Reverb, Delay, Compressor, Chorus.
