Hi there
I have a electronic schematic that I am trying to get my head around without much luck
As you can see (picture below) the circuit is a differential amplifier being fed from a 3 pin DIN connector
On the input to the amplifier are two resistors that are connected together (R101 and R102) and also joining the amplifier inputs together, I am struggling to understand the purpose of these resistors. As far as I can make out these are to balance the input to the amplifier, but this is a very strange way of doing it. Has anybody seen this configuration before and is able to explain to me how it works?
I have looked up a lot on input balancing to an op amp and can't see it being done this way anywhere at all.
Many thanks in advance
