Hifisonix Speaker Protection PCB

This PCB uses the Unisonic uPC1237 and provides DC offset protection and switch ON/OFF muting.  Rather than use a relay to connect the loudspeaker to the amplifier, the Hifisonix Speaker Protection Board uses mosfets which do not suffer from arcing or any other wear out mechanisms.  Additionally, there is a short circuit input provided that can be triggered by a user circuit.  The board will work on voltages from 20V through to 75V (requires some resistor changes – all details provided in the write-up).
