Title: Part No. STK463
Introduction:
An audio or stereo amplifier (or power amp) is an electronic amplifier that amplifies low-power electronic signals such as a signal from a radio receiver or electric guitar pickup to a high enough level by driving through audio speakers or headphones. Audio Power amplifiers are available in all types of audio equipment including audio stabilizers, public address and home audio systems and musical instruments such as guitar amplifiers. It is the last normal electronic stage to play before the signal is sent.
Core Parameters:
Bandwidth between two signals
Efficiency
Distortion
Impedance
Working:
While the input signal of an audio amplifier, such as a signal from an electric pipe, can measure a few hundred microwatts, its output can be a few miles of consumer electronics devices, such as clock radios, tens or hundreds of watts of a home stereo system, thousands of watts a few of the nightclub sound systems or tens of thousands of watts of a massive rock concert sound system. While power amplifiers are available in standalone unit units, usually aimed at the hi-fi audiophile (niche market) for audio lovers and sound system professionals, many electronic audio products, such as clock radios etc An absolute or ideal amplifier will give us a good rating of 100% or at least “IN” power equal to “OUT” power. However, in reality this does not happen at all as some energy is lost in the form of heat and again, the amplifier itself uses energy during the amplification process.
Applications:
In home theatres
Radios
Guitars
Home cinemas
