Converts sound signals of line level (approx 1 volt) into tens of volts, with currents of around 1 Amp to drive speakers
An amplifier which provides high power gain to a wireless transmitter Typical figures of merit include gain, efficiency and linearity (in amplitude and phase modulated systems) and stability *
An amplifier that delivers a certain amount of alternating-current power to a load Used in audio-frequency and radio-frequency applications
The amplification device which boosts the level of a line-level signal in order to supply sufficient power to directly drive a speaker
Takes the low powered output from a Pre Amplifier (see below) and drives the speakers By separating the Pre amplifier stage from the Power amplifier stage, normally contained within the same box in a stereo integrated amplifier, the internal interference is reduced giving a stronger, higher quality sound The Power amp takes the variable signal and amplifies it by a fixed amount - the volume is controlled by the Pre amplifier
A class of amplifiers that have the primary purpose of delivering high output power (usually accompanied by significant dissipated power)
An electronic device that increases the volume of a signal A basic unit of all sound systems Power amps are typically connected to a preamp which provides controls for individual functions: level, tone, etc
A component, or part of a component, that strengthens the audio signal from a pre-amplifier so that it can drive speakers
The final stage of amplification (e g , You must use a power amplifier to drive your speakers )
An amplifier that takes line level audio signals and make them strong enough to power a speaker
As opposed to a pre-amplifier, the power amplifier can produce am audio signal with enough energy to drive for example a speaker or a pair of headphones The amount of output signal power is normally measured in Watts (W) A power amplifier (or "power amp" for short) is by nature an analogue device, by the way
