The primary role of an enclosure is to prevent sound waves generated by the rearward-facing surface of the diaphragm of an open speaker driver interacting with sound waves generated at the front of the speaker driver. Because the forward- and rearward-generated sounds are out of phase with each other, any interaction between the two in the ...
Funktion-One Russia supplied and installed a permanent state of the art sound system for Volgograd Arena — one of the Russian World Cup 2018 stadia. Working closely with the Funktion-One design team in the UK, the company specified a system that features 638 Funktion-One loudspeakers and 50 MC2 Audio amplifiers.
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude (magnitude of the voltage or current) of a signal applied to its input ...
A sound reinforcement system for a rock concert in a stadium may be very complex, including hundreds of microphones, complex live sound mixing and signal processing systems, tens of thousands of watts of amplifier power, and multiple loudspeaker arrays, all overseen by a team of audio engineers and technicians.
The electrical signal generated by the coil travels back along the speaker cable to the amplifier. Well-designed amplifiers have low output impedance so that this generated signal has minimal effect on the amplifier. Characteristically, solid state amplifiers have had much lower output impedances than tube amplifiers. So much so, that ...
It is known that it is the 'brilliant' model (or top boost) and it was Edge's earliest amp used to record every U2 album Since the higher output AC30/4 shared its preamplifier design with the lower powered AC15, Vox discovered the high-gain EF86 tube was susceptible to microphonics, or even failure, when exposed to the increased vibration ...

In 1994 Karsten Nielsen began to write a Ph.D. dissertation "Audio Power Amplifiers Techniques Based on Efficient Power Conversion" [2] at the Technical University of Denmark as part of a project in collaboration with Bang & Olufsen; his findings were applied in the Beolab 1 active loudspeakers in 1997, and he was awarded a Ph.D. in 1998.
