In this project, we'll use analog control since it's the easiest way to get going with the amplifier board. By default, the amplifier breakout is in digital mode. To put it in analog mode we need to close the three solder jumpers labeled Analog, AD1 and AD2.
The terminal blocks will be used to connect the two speakers to the audio output of the MAX9744. Follow the negative and positive symbols and insert them appropriately. Solder them in to place for a solid connection.
Insert the capacitor with the longer lead going into the pad marked + Push it in all the way and bend the leads to keep it in place while you solder it in.
We're using a panel mount style potentiometer which is a bit bigger than the 1k pot that comes with the kit. Solder three strands of wrapping wire to the pin outs labeled Pot. Vol. Line up the leads of the pot with the pins to ensure turning it to the right will increase the values. Solder the far right lead of the pot to Pot. Vol. pin 3
