The display shows all important values like system time, current sound level in different values
(dBA, dBC, Leq and line level) and the current reduction.
3. Timeslots:
these LED's indicate the current active timeslot. Each timeslot can be configured with it's own
time and maximum sound pressure level.
4. Status LED's:
•
AUDIO PRESENT indicates active audio detected on the audio inputs of the limiter (detects
at -24dB),
•
REDUCE LED indicates the limiter is actively reducing the audio signal,
•
OVERLOAD LED indicates an overloaded signal present at the line or microphone input
(12dB above threshold level),
•
SANCTION LED indicates the limiter in sanction state. On fraud detection the limiter will also
go into sanction state. The sanction LED will blink. Reset by timer or reset key.
1. Reduction LED's:
The reducion is indicated in the percentage of the maximum allowed limiter reduction. Default
this is set to 30dB that results in 6dB/LED.
•
All off: no reduction

5 LED's on: 80-100% reduction
2. Bypass switch:
This switch puts the limiter fully in bypass. The limiter will no longer act as limiter, but will only
record measured sound levels.
3. USB:
USB connection for reading historic sound levels and changing the limiter settings.
4. Bypass LED:
Indicates the limiter is in bypass mode. The bypass switch or bypass callander is active.
5. Key switch:
After removing the cover lid, the key needs to be set to the blue position to reactivate the
limiter. After reactivating the key needs to be returned to the red position. The key switch also
resets sanction.
