Audio SI (Stereo Imbalance)
This page allows the user to set mainly the audio imbalancement between channel Left and Channel Right threshold and
timing, for Stereo Signal. Stereo Imbalance alarm and about 18 new Oids in the Audio Module branches and two new
traps. This new alarm rise
s up when the audio levels if the unbalance “abs(RmsLeft-RmsRight)” averaged in the “AVG”
time is greater than the threshold value more than validation time. The AVG is calculated using a single pole IIR filter with
the constant time equal to the AVG time. That means that the AVG time is the time required to reach about the 70% of
the final value. The measurement value is available with all input sources, but the alarms and traps are available for the
Tun1 e Tun2 sources only. MIB L4-0 is required.
NAME DESCRIPTION NOTE
Chan
Channel Number
Chan Label
Mnemonic name that can be applied to the Channel / Frequency
Frequency
Frequency corresponding to the Channel, expressed in MHz
Preset
String used by the configurator
Scan Time
This value represents the time in s that the tuner remain on this frequency.
Chan Mask
This control allow (or not) the channel to be under control.
Avg
This is the Average time considered for the Threshold and generate an alarm in
case of Stereo Audio Imbalancement
Validation
This parameter is related to Avg, after this <Validation> the incoming audio is
considered “Imbalanced” and an alarm will be delibered
Hold
is the time between the cessation of the alarm condition and alarm signaling finished
Mask
It is possible to set, for each single parameter: unmasked, masked, severity-1,
severity-2, severity-3, RFL2 mask.
Email
In case the alarm/error raise up, the Wolf 2MS sends an email if <enable>.
If is <disable> no action are taken.
Trap
In case the alarm/error raise up, the Wolf 2MS sends a trap if <enable>.
If is <disable> no action are taken.
Label
This is the label/content that the user can choose to shows via email or in the trap in
