CX233 I NSTALLATION AND OPERATION MANUAL 7
10 Unbalanced Mode
If the zone outputs are required to operate in the unbalanced mode, it is suggested that
the unused pin of the XLR connector is not connected. The nominal output signal in this
mode is -6dBu and a small amount of extra gain may be required.
