Introduction:
An audio amplifier (or power amp) is an electronic amplifier that amplifies low-power electronic signals such as 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 final electronic stage of audio playback before the signal is sent to the speakers.
Core Parameters:
● Hybrid ic design
● Compatible output from 80w to 150w
● Output load design 6ohm
● Available load shorted time 0.3 sec
● Mute circuits standby

Working:
Crucial model factors for audio amplifiers are frequency response, gain, noise, and distortion. This depends; increased profitability often leads to undesirable noise increases and distortion. While negative feedback decreases profitability, it also reduces distortion. Most audio amplifiers are direct amplifiers operating in the classroom AB. It is the final electronic stage of audio playback before the signal is sent to the speakers.
Applications:
● Aim of this module for the audio amplification of the signals
● It is used for high power amplification of the circuit
● Amplifier design circuits
● For cascade audio speakers
