Amp Rack Units

Amp rack units refer to an assortment of rack-mounted or rack-protected PA amplification or sound reinforcement equipment that is set up to work with a mixer and loudspeakers. An amplifier, also called a power amplifier, is a basic signal processing unit that increases the power of an audio signal to make the sound from a human voice or music louder. A pro audio amplifier is used in professional sound systems as the last active component in the signal chain because it receives input from mixers or other signal processing units, increases the power of the signal, and sends the output to speakers. There are other types of amplifiers also referred to as amp rack units. A touring amplifier is simply a power amplifier that is designed to withstand conditions that touring musicians are exposed to especially being on the road most of the time. Live power amplifiers are used to support the audio demands of live performances. These amps make help create the unique experience of sound in live concerts. Some amp rack units are built by combining or adding amplifier modules with other parts. These are amplifier sub-units or parts designed to meet certain specifications. To have a whole amplification unit you may need a transformer, bridge rectifiers and filter capacitors, speaker connectors, input connectors, volume control, heatsink and a suitable rack mount case.
