The Jazz Chorus is one of the most famous and successful combo amplifiers from its period and its earliest users included Albert King, Andy Summers (), Chuck Hammer (), Larry Coryell, Robert Smith (of The Cure, although he used the rarer 160 Watt JC-160 with 4 x 10" speakers), Billy Duffy (The Cult, Theatre of Hate), Roger Hodgson of Supertramp, Joe Strummer, John Sebastian of The Lovin ...
An '84 dB' source would require a 400-watt amplifier to produce the same acoustical power (perceived loudness) as a '90 dB' source being driven by a 100-watt amplifier, or a '100 dB' source being driven by a 10 watt amplifier. A good measure of the 'power' of a system is therefore a plot of maximum loudness before clipping of the amplifier and ...
Audio stereo power amplifier made by McIntosh The internal view of a Mission Cyrus 1 Hi Fi integrated audio amplifier (1984) [1]. An audio power amplifier (or power amp) amplifies low-power electronic audio signals, such as the signal from a radio receiver or an electric guitar pickup, to a level that is high enough for driving loudspeakers or headphones.
The solution is to use fill-in speakers to obtain good coverage, using a delay to ensure that the audience does not hear the same reinforced sound at different times. The number of subwoofer speaker cabinets and power amplifiers dedicated to low-frequency sounds used in a club depends on the type of club, the genres of music played there, and ...
The gain of a good quality full-range audio amplifier will be essentially flat between 20 Hz to about 20 kHz (the range of normal human hearing). In ultra-high-fidelity amplifier design, the amplifier's frequency response should extend considerably beyond this (one or more octaves either side) and might have −3 dB points < 10 Hz and > 65 kHz.
Driving an amplifier to 1% distortion levels will yield a higher rating than driving it to 0.01% distortion levels. [14] Similarly, testing an amplifier at a single mid-range frequency, or testing just one channel of a two-channel amplifier, will yield a higher rating than if it is tested throughout its intended frequency range with both ...

The human ear perceives a 5-watt amplifier as half as loud as a 50-watt amplifier (a tenfold increase in power), and a half-watt amplifier is a quarter as loud as a 50-watt amp. Doubling the output power of an amplifier results in a just noticeable increase in volume, so a 100-watt amplifier is only just noticeably louder than a 50-watt amplifier.
