You probably have needed to match impedances and levels from time to time. Perhaps you want to connect a consumer computer’s sound card to your console; or you need to lower a balanced output level to ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
