Order #698185-9006499639
I have soldered the unit together and tested it. The volume control is totally dysfunctional and has no effect. There is one volume level and it is significantly less then 10 Watts as compared to the 10 Watt TV I have
I verified the pot soldering. Connections are good (tested with ohmmeter)
I tested with 2 sources and the result is identical. Output is at one level and volume control has no effect.
My best guess is that amplification is about 5 watts :-(
I believe this is a defective board. Please advise and or send another unit to replace this one

Re: 20W Class D audio amplifier
f you want to control the volume with a pot, you have to put the module into analog mode. See the instructions on the back of the module. You need to close the Analog, AD1, and AD2 jumpers.
