The audio bridge is to connect form the back of a base interface module (BIM) which is 4-wire audio Tx & Rx (ear to mouth this is a communications term used with telecom & microwave)
The 4 wire audio would connect into the bridge in needs to be 600 ohms the output with matching resistors to allow equipment of board on the other side.
I need help designing the audio bridge which needs to be a balance circuit to match the impedance of 600 ohms The 600 ohms is the 4 - wire audio impedance.
