Operation
1. Power on/ off switch
2. Display: This contains all important data, like the time, actual sound pressure level (dBA value
and peak value). Furthermore it contains the following notifications:
Warning: The limiter has encountered an error. This can vary from a hardware failure to a
•
possible sabotage attempt. The volume will be reduced drastically until the problem is
solved. Establish a connection with the computer get a more detailed problem description.
The active TimeSlot LED will start blinking, indicating a reduced output level. The sanction
LED will blink to indicate the type of error message:
80% on/ 20% off: A problem with the power supply
20% on/ 80% off: Measuring microphone disconnected of defective
50% on/ 50% off 1x per sec.: Illegal configuration or cover removed
50% on/ 50% off 2x per sec: Memory full
Level: The current sound pressure is exceeding the maximum allowed sound pressure.
•
Muted: The outputs of the limiter are disabled, this occurs when booting the limiter.
•
Calibr.: The limiter needs calibration.
•
Live: The limiter is functioning in live-mode. This means that the measured audio is not
•
produced by the limiter and the power amplifiers, but by a live-band. The limiter will not
correct the sound pressure level. When the maximum sound level is exceeded a sanction
will follow. The stage equipment can be switched off if desired.
3. Timeslot LEDs: These LEDs indicate the active time-slots. Each time-slot has it's own
maximum sound pressure level. When the LED is blinking the maximum audio level is reduced.
Possible reasons are:
When switching between TimeSlots,
•
During an error status of the limiter,
•
When the external attenuator is active.
•
4. Status LEDs:
Audio-present LED indicates the detection of audio signal on the line-in input (activated at
•
-24dB),
Audio-reduction LED indicates the attenuation of the sound pressure level,
•
Overload indicates that one of the inputs (line or microphone) is overloaded,
•
Sanction LED indicates a sanction status of the limiter (LED lights up without blinking) or the
•
limiter is in error mode (LED is blinking; see above).
