Amplifier

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 centre tap of a full-wave rectifier circuit. The current in the centre 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 utilisation 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 ...

Biassing

Consumer electronics; Amplifier

The term commonly used for the practise of setting the idle current in an output tube. Preamp tubes are biassed as well, but they are biassed only during the initial design of the amplifier and use ...

Bridge rectifier

Consumer electronics; Amplifier

A set of four rectifiers arranged in a square shape. The four diodes allow full-wave rectification without the need for a center-tap on the transformer.
