2.1.2 LEFT/RIGHT connectors
N. 5 Rear panel (XLR type - female)
The input impedance is 10 kOhm (default), 600 ohm selectable with jumpers on the
card.
If you have an unbalanced signal, connect the signal at the positive, the common
ground and the negative input to ground (optional if Zin = 10 kOhm, required if Zin =
600 ohms).
