.
If loudspeaker line
surveillance is required,
tick the check box
(7)
.
Select an
AUDIBLE
frequency for
surveillance (8)
. Use
the sliding controls
(9)
and
(10)
to set the
precision of line
surveillance detection.
The closer the control is
moved to 1%, the more
accurate detection is. We
recommend a setting of
20% (default value).
Select a
NO AUDIBLE
frequency for
surveillance (11)
. Use
the sliding controls
(12)
and
(13)
to set the
precision of line
surveillance detection.
The closer the control is moved to 1%, the more accurate the detection is. We recommend a setting of
20% (default value).
ATTENTION: Excessive precision can lead to the detection of “false” errors, since the
behaviour of the loudspeaker lines is often affected by environmental factors that are not
related with the Public Address system (noise captured by the loudspeakers, temperature,
humidity, magnetic fields…).
Select the
Options
tab
(14).
Configure whether upon detection of
a line error you wish to stop the
music to perform surveillance of this
line again.
Configure the interval of time
between two consecutive line
surveillance sessions, using
NONAUDIBLE frequencies. Enter a
value between 0 and 1440 minutes
(Select the value “0” for continuous
surveillance; Select Off to deactivate
surveillance at intervals of time).
Then click on
Next (1).
