Hi - I am using several of the Audio FX Mini-Sound Boards (product ID 2342) to create a series of tones that I want to mix into a single output to a speaker. My thinking is to use 10K resistors at the outputs of the Mini-Sound BDs & join them at the input to the 20W Class D Amplifier 9722.
See attached sketch - can I mix the inputs to the Amplifier like this?
Thanks for any help that you can give me.
