amplifier (amp)

Consumer electronics; Amplifier

An electronic device that increases the level of an audio signal, usually for the purpose of driving one or more loudspeakers, or for maintaining proper levels in long signal chains (multiple ...

anode

Consumer electronics; Amplifier

The "current collecting" element of an electron tube, also called the "plate". The anode usually has a large positive voltage connected to it in order to attract the negatively-charged electrons ...

attenuator

Consumer electronics; Amplifier

A passive network designed to reduce the voltage or power of a signal. Typically, this is accomplished with two resistors, one in series with the signal and the other from the output of the first ...

A method of obtaining a negative bias voltage by means of a resistor or zener diode in the center tap of a full-wave rectifier circuit. The current in the center tap flows in the same direction for ...

balanced connector

Consumer electronics; Amplifier

A 3-conductor connector - commonly referred to as an XLR or Cannon connector that terminates a cord carrying a signal over three wires. One wire acts as a ground, while the others carry the signal in ...

bass control

Consumer electronics; Amplifier

A tone control that affects low audio frequencies (typically below 500Hz).

biamping

Consumer electronics; Amplifier

The utilization of two amplifiers in a given sound system in order to separately amplify different frequency ranges and thereby reduces distortion. Usually, a full-range audio signal is divided by ...
