The Roland Micro Cube, left, a small and portable digital modeling amplifier. Digital amp modelers Standalone modeling devices such as the Line 6 POD and Fractal Axe-FX digitize the input signal and use a DSP, a dedicated microprocessor, to process the signal with digital computation, attempting to achieve the sound of expensive professional amplifiers in a much less costly and more compact ...
Audison is one of the brands of the Italian company Elettromedia s.r.l., a manufacturer of car audio products. The company was founded in 1979, but Audison name (born from Latin words Audio and Sonus) was registered in 1984. Currently Audison has different kinds of mobile audio products: amplifiers, audio processors, speakers and subwoofers.
Many electric guitar players intentionally overdrive their amplifiers (or insert a "fuzz box") to cause clipping in order to get a desired sound (see guitar distortion).. Some audiophiles believe that the clipping behavior of vacuum tubes with little or no negative feedback is superior to that of transistors, in that vacuum tubes clip more gradually than transistors (i.e. soft clipping, and ...

Since the development of digital signal processing (DSP), there have been many pieces of equipment and computer software designed to shift the bulk of the work of system calibration from human auditory interpretation to software algorithms that run on microprocessors. One tool for calibrating a sound system is a real-time analyzer (RTA).
QSC is an American manufacturer of audio, video and control products such as amplifiers, loudspeakers, cameras, video endpoints, and digital signal processors including the Q-SYS networked audio, video and control platform. QSC and Q-SYS products are used by audio and video professionals for commercial applications, including corporate, higher ...
Class-D amplifiers use switching technology to achieve high efficiency, often exceeding 90%, thereby requiring less power to operate, compared with that of other amplifier types. Because of the digital train used to drive the amplifier, many do not consider the Class-D amplifier a linear amplifier, yet many audio and radio manufacturers have ...
A lock-in amplifier is a type of amplifier that can extract a signal with a known carrier wave from an extremely noisy environment. Depending on the dynamic reserve of the instrument, signals up to a million times smaller than noise components, potentially fairly close by in frequency, can still be reliably detected.
