Great question.  I am repairing one at the moment and have just realised there is no external trigger input.  There are a few sockets with nothing plugged into it, SWEEP OUT, MTB GATE,DTB GATE.  The external trigger section does not have a socket installed.  I can't seem to find any info on the options and whats entailed.   Does anyone have any info on this?
