I just received a remote volume control kit with switchable inputs from DIY Club (MV-01). However there are no instructions or even a schematic for it.
Some of the connections are easy, even for me such as things labeled 12V, 5V or Gnd. I'm assuming the 'a b c' connector is for the IR receiver but which pin is which?
The input switching relay board has a 6 pin connector that looks the same as one on the volume control board so it would be a decent guess they get hooked together- but... pin 1 to pin 1 or reversed? It appears the inputs should be soldered to the through-hole pads but maybe they go the the 7 pin connector?
As you can see I'm confused! If anyone here has ever used one of these I'd appreciate any help!
