Brooks QS 70 Capsule

1) The variable capacitor section of a condenser microphone.
2) In other types of microphones, the part of the microphone that includes the diaphragm and the active element.

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 Audio Design Review SS 81 Direct box
Used in line to convert a high impedance signal into a low impedance signal.

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 SS 81 High-Pass Filter
A device that rejects signals that are below a certain frequency (called the cut-off frequency) and passes signals with frequencies that are higher.

CD-ROM
An abbreviation of the term Compact Disc, Read Only Memory (A Compact Disc used to store digital data, such as large programs, that can be read by a computer).

Acoustic Amplifier
The portion of the instrument which makes the vibrating source move more air or move air more efficiently; this makes the sound of the instrument louder. Examples of acoustic amplifiers include:
1) The body of an acoustic guitar,
2) The sounding board of a piano,
3) The bell of a horn and
4) The shell of a drum.

Generating Element
The portion of the microphone that actually converts the movement of the diaphragm into electrical current or voltage changes.
