Wohler Alarm Profile Editor Installation and Operation
Section 2: Operation
Stereo: Alarm Profile Editor Screen (Continued)
Each Alarm Profile consists of five parameters:
Loss Amplitude:
A threshold in dB (with respect to
Digital Full Scale
) below which
Silence
is deemed to be active.
Loss Duration:
A qualifying period that the
Loss Amplitude
criteria has been met. When
Loss Amplitude
has been met for
Loss Duration
then a
Loss of Audio
alarm condition has been met. The unit will then trip into and report that alarm.
Over(load) Amplitude:
A threshold in dB (below
Digital Full Scale
) above which
Over
is deemed to be active.
Over(load) Duration:
A qualifying period that the
Over Amplitude
criteria has been met. When
Over Amplitude
has been
met for
Over Duration
then an
Overload Audio
alarm condition has been met. The unit will then trip into and report that alarm.
Phase Duration:
A period that average signal out of phase has to be met to trip an
Audio Phase
alarm condition.
Notice that the odd and even channels are "ganged together" for
Stereo
operation. By selecting profile
2
for channel
3
, channel
4
also has that profile assigned to it.
