5. Audio Connection

To transmit a preamplified signal (OUTPUT connector on the PSUT), use a balanced microphone cable with the following pin assignment:

pin 1 = shielding; pin 2 = +; pin 3 = -. Since your PSUT features gold-plated contact points, we recommend that you use only microphone cables with gold-plated connectors.
