Trigger
When a trigger cable is connected to the Trigger Input (on the rear panel), and a trigger signal is
received (between 5-20 V - AC or DC), the XPA-2 will switch from Standby to On; when the trigger
signal ceases, the XPA-2 will return to Off.
The trigger is typically connected to the preamp or pre/pro that provides a signal source for the
XPA-2, and set to turn the XPA-2 on when the preamp or pre/pro is turned on.
Whenever the XPA-2 is On, the Trigger Output will assert a 12 VDC signal, which may be used to
turn on other trigger-enabled equipment.
