QSC Audio PL230A - Manual (Page 8)

DATAPORT INPUT SIGNAL- This switch selects the regular inputs or the
DataPort inputs, and allows the DataPort to enter before or after the analog
processing. WARNING: There is no DataPort “flag” for this setting, so the appropriate
setting must be confirmed manually.
FEATURES & SETUP- REAR PANEL SWITCHES: DATAPORT INPUT SIGNAL
OFF: If the DATAPORT CONNECTION is not being used, set to the OFF position. The
DataPort MONITOR SIGNALS and STANDBY are still active, but the DataPort input signals
will not reach the amplifier.
PRE PROC: This setting will insert the DATAPORT signals ahead of the amplifier’s signal
processor. If you are using external processing on the DATAPORT input signal, be aware that
additional internal processing will be added to the signal. This may cause unexpected overall
results.
POST PROC: This selection inserts the DATAPORT signals after the amplifier’s processor.
The subaudio filters and clip limiting remain functional, but all other processing is
bypassed. See the Block Diagram for more detailed signal flow information.
