Amplifier

Footswitch

Consumer electronics; Amplifier

A foot-triggered switch used to activate an amp’s reverb, vibrato, or other feature, as well as effects devices.

Frequency response

Consumer electronics; Amplifier

The range of frequencies over which a device or audio system will perform.

A rectifier that conducts on both positive and negative halves of the incoming sinusoidal signal. It produces a "pulsating" DC composed of single-polarity "humps" at twice the incoming AC frequency. ...

Capacitor

Consumer electronics; Amplifier

A device consisting of two parallel plates separated by an insulator, called the "dielectric". Capacitors are used to block DC while passing AC. They are frequency-dependent devices, which means ...

Cascading

Consumer electronics; Amplifier

Switching or wiring in extra preamplifier stages in series to achieve higher gain.

Cathode

Consumer electronics; Amplifier

The "current generating" element of an electron tube. The heater heats the cathode to a very high temperature, causing it to emit electrons, which are then collected by the anode, or plate, which ...

Cathode biassing

Consumer electronics; Amplifier

A method of biassing a tube where the bias is generated by the voltage drop across a resistor in the cathode. The grid is referred to ground through a resistor, and the current flow through the ...
