B. Loudspeaker Line Surveillance.
If loudspeaker line surveillance is not required in this zone, click on Next (16).
If loudspeaker line surveillance is required, tick the check box (17).
Select an AUDIBLE frequency for surveillance (18). Use the sliding controls (19) and (20) 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 an NO AUDIBLE frequency for
surveillance (21). Use the sliding
controls (22) and (23) 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).
N.B.: Excessive precision can lead
to the detection of "false" errors,
since
the
behaviour
loudspeaker lines is often affected
by
environmental
related with the public address
system
(noise
captured
loudspeakers,
humidity, magnetic fields...).
Click on Next (16).
Click on the Check Spk. line button
(24). In this way, a check is made that
there are no short circuits between the
various loudspeaker lines.
If the result is not correct, check the
loudspeaker line and once the problem
has been resolved, check the line once
again.
If the result is correct (OK), click on
the Start Adjustment button (25).
