Amplifier

crossover

Consumer electronics; Amplifier

A circuit that divides a signal into two or more bands of selected frequencies; often used in biamping or triamping.

crossover distortion

Consumer electronics; Amplifier

Distortion caused by a slight delay in amplification at the crossing-over point between the top and bottom devices in a push-pull amplifier circuit.

current

Consumer electronics; Amplifier

The term given to electron flow. The unit of current is the "amp", or "ampere", and indicates a current flow of one coulomb per second. A coulomb is a unit of electron charge.

cutoff frequency

Consumer electronics; Amplifier

The "corner point" of a filter, usually the point where the response is down -3dB compared to the midband signal level.

dB (decibel)

Consumer electronics; Amplifier

A unit of measurement for expressing the ratios of various quantities including sound level, power, and voltage.

DC (direct current)

Consumer electronics; Amplifier

Electric current that has constant and uniform polarity (flows in one direction). Batteries and small power sources for effects provide a source for DC.

The process of seperating one stage of an amplifier from another. Decoupling prevents oscillations and other noises that may occur due to unwanted feedback through the power supply connections. It ...
