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.
600 watt transformers are widely available for contractors needing high power loudspeakers in constant-voltage installations. [12] Special-purpose transformers capable of handling 1250 watts down as low as 50 Hz are available. [4] One problem with high power, high current transformers is that fewer can be used on a single constant-voltage line.

The 3000 Xtra system was first released in 1999, but in many ways was a continuation of previous Reuters products that included Equities 2000 (released in 1987), Dealing 2000-2 (released in 1992), 3000 Series (released in 1996) and "Advanced Reuters Terminal" (released in 1986).
Sound power or acoustic power is the rate at which sound energy is emitted, reflected, transmitted or received, per unit time. [1] It is defined [2] as "through a surface, the product of the sound pressure, and the component of the particle velocity, at a point on the surface in the direction normal to the surface, integrated over that surface."
For example, a subwoofer rated at 100 watts may be able to handle 100 watts of power at 80 hertz, but at 25 hertz it might not be able to handle nearly as much power since such frequencies would, for some drivers in some enclosures, force the driver beyond its mechanical limits much before reaching 100 watts from the amplifier.

The triode was a three-terminal device with a control grid that can modulate the flow of electrons from the filament to the plate. The triode vacuum amplifier was used to make the first AM radio. [2] Early audio power amplifiers were based on vacuum tubes and some of these achieved notably high audio quality (e.g., the Williamson amplifier of ...
A large club may use several power amplifiers to provide 1000 to 2000 watts of power to the main speakers. An outdoor rock concert may use large racks of a number of power amplifiers to provide 10,000 or more watts. The monitor system in a coffeehouse or singer-songwriter stage for a small bar may be a single 100 watt powered monitor wedge.
