Hi,
I have built 2 LM3886 amps using the datasheet from national semiconductor. I want to be able to select normal 2-channel 68W, bridged 220W 1 channel, or parallel 68W 1 channel. The normal mode is to operate stereo speakers, the bridged is for driving an 8-ohm speaker, possibly a subwoofer, and the parallel is for driving a low efficiancy 4-ohm speaker, or normal 2-ohm speaker. How do I connect the two amps together. If anybody could tell me what to connect, I could figure out the switches to select the modes.
Thanks, Mike
