That is an audio energy amplifier board that strengthens low-power, inaudible digital audio indicators such because the sign from radio receiver or electrical guitar pickup to a stage that’s sturdy sufficient for driving loudspeakers or headphones. Energy amplifiers make the sign audible to listeners. It’s the last digital stage in a typical audio playback chain earlier than the sign is shipped to the loudspeakers and speaker enclosures.
