4.8.5.5.2 Ext Rear (Trigger In)
Selects the rear panel external trigger input connector as the gate source and sets the
voltage level at which the gate will trigger. Changes made to the trigger level setting with
this key will also change the setting in the
Trig menu.
This key also defines the voltage level at which the gate will trigger.
NOTE Be careful about selecting trigger level values too far away from the trigger
signal’s midpoint. If the signal has ringing, it can cause multiple triggers.
