Brooks Hi Fi speakers 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.

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.

Brooks RM 909 reviews Ground Lift

A Compact Disc used to store digital data, such as large programs, that can be read by a computer.

Brooks Hi Fi reviews Equal Loudness Contours
A drawing of several curves showing how loud the tones of different frequencies would have to be played for a person to say they were of equal loudness.

High Impedance Mic
A microphone designed to be fed into an amplifier with input impedance greater than 20 k ohms.

Compact Disc, Interactive CDI
A Compact Disc, usually containing audio, video, and text, which the user can interact with in that the display or playback changes after the user performs some action.

In
Short For "in the circuit," in other words "active."
