STK402-071 is 2 Channel AF Power Amplifier. An AF (audio frequency) power amplifier is an electronic amplifier designed to amplify audio signals in the audible frequency range, typically from 20 Hz to 20,000 Hz. These amplifiers are used to increase the power of audio signals, making them suitable for driving speakers or other audio transducers. AF power amplifiers are a critical component in audio systems, including stereo systems, home theaters, public address systems, musical instrument amplifiers, and more.
