The MCB2400 board includes a speaker controlled by the output of the on-chip D/A converter, and the volume control (R71). The LM386M low voltage power amplifier (U15) amplifies the D/A output to drive the speaker.
The D/A output (Port 0, pin 26, P0.26/AOUT) is connected to the input of the LM386M amplifier.
