speakers have a low impedance, typically 8-Ohm. Even for a low-power 0.5W audio amplifier, PIR 2 /2 requires that the amplifier must be able to source a peak AC current of around 350 mA with an 8-Ohm load. This is a lot more than a typical op-amp is designed to provide. For example, the LM358 and LF353 (two op-amps used in this lab) can source

An amp is only supposed to amplify an audio signal without adding, deleting, or changing the signal in any way other than to make it louder. Virtually all decent amps (both medium and high end) amplify sound without audible distortion. Therefore when I see amps listed as bright sounding I can't help but wonder why. ... They even have the gall ...

Amplifiers. The task of an audio amplifier is to take a small signal and make it bigger without making any other changes in it. This is a demanding task, because. a musical sound usually contains several frequencies, all of which must be amplified by the same factor to avoid changing the waveform and hence the quality of the sound. An amplifier ...
