Brooks HI FI projectors Audio

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

Capacitor
1) A device consisting of two or more conducting plates separated from one another by an insulating material and used for storing an electrical charge. Sometimes called a condenser.
2) An electronic device that is composed of two plates separated by an insulator.

Brooks Hi Fi reviews Direct box
Used in line to convert a high impedance signal into a low impedance signal.

Aliasing
A sampler mis-recognizing a signal sent to it that is at a frequency higher than the Nyquist Frequency. Upon playback, the system will provide a signal at an incorrect frequency (called an alias frequency). Aliasing is a kind of distortion.

Brooks 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 (Crossover Network)
A set of filters that "split" the audio signal into two or more bands (two or more signals, each of which have only some of the frequencies present).

Insulator
A substance such as glass, air, plastic, etc., that will (for all practical purposes) not conduct electricity.

Echo Return
An input of the console, which brings back the echo (reverberation) signal from the echo chamber or other echo effects device.
