20.1.3 Exceedance SLM thresholds (Exc_slm_threshold)
User input of two level values Max and Min is required: start threshold or stop threshold depending on
the selected mode (POS, NEG, IN, OUT).
Trigger start threshold: the threshold for triggering on the level reached by the selected parameter.
Trigger stop threshold: a separate deactivation threshold for triggering on the level reached by the
selected parameter.
20.1.4 SLM exceedance duration filter (Exc_slm_duration)
A duration filter is available to eliminate false triggers. An event is only triggered if the over level condi-
tion persists for a number of seconds at least equal to this parameter (parameter value 0-10s).
20.1.5 Enabling SLM exceedances (Exc_slm_enable)
Enables or disables the use of exceedance on SLM (Trigger Input) parameters
Red bell = ON
Grey bell = OFF
20.2 Setup trigger
(EDIT APP > TRIGGER > SETUP or SETTINGS > TRIGGER > SETUP)
General trigger parameters are available for setting on SETUP menu
20.2.1 Pre-trigger
This is the time interval before the trigger occurrence. The event generated by the trigger activation
will also include the configurable time interval before the trigger activation. The function makes it pos-
sible to also detect or include in the calculations the level increase phase of a sound event or particular-
ly fast events whose phase before the trigger is triggered. (parameter value 0-10s)
20.2.2 Post-trigger duration
After the deactivation threshold is reached, the trigger remains active for a user-settable time. It is pos-
sible in this way, for example, to encode the 'tail' of a sound event (parameter value 0-3600s).
