Hi
I am trying to combine four amplified (about 3W RMS into 8 Ohms) outputs to feed one speaker only. This is not a HiFi setup, one voice and 3 beeping inputs. I have found some schematics, but they generally deal with line level sources. This is not possible in this case as I cannot get to the line level signals. I am looking for the simplest unpowered solution if it exists. One of the most important considerations is not to damage the originating equipment.
Any help greatly appreciated.
