A Class AB Quad Channels Audio Power Amplifier is an electronic device or integrated circuit (IC) designed to amplify audio signals, typically for driving speakers or other audio output devices. The term “quad channels” indicates that it has four separate amplification channels, allowing it to amplify and output audio to four different speakers or audio channels.
