To transmit a preamplified signal (OUTPUT connector on the PSU-T),
use a balanced microphone cable with the following pin assignment:
pin 1 = shielding; pin 2 = +; pin 3 = -. Since your PSU-T features gold-plated
contact points, we recommend that you use only microphone cables with
gold-plated connectors.
