Level Adjustment - Johansson Profiler Lite 6601 Mode D'emploi

LEVEL ADJUSTMENT

Levels are manually set for each input and / or automatically for the UHF clusters.
Automatic level setting
The levels of BI-II / BIII are not processed in the Auto Level function.
- Turn the button to choose the Auto Level.
- Push the rotary button for more than 3 seconds to start the Auto Level function.
The level of each cluster is set automatically.
This procedure will take about 1 to 2 minutes, depending on the number of channels and clusters
to be equalized.
- When the LED is GREEN, the procedure is finished.
- Each cluster's LED shows the status of equalization.
Notes :
- The automatic level adjustment set the output level of the clusters at 90 dBμV
(for an input level between 50 to 80 dBμV).
If the input level is less than 50 dBμV, the LED will blink slowly after the automatic level adjustment.
If the input level is higher than 80 dBμV, the LED will blink rapidly after the automatic level adjustment.
Adjust the input level (attenuation or amplification) if necessary.
- The general attenuator is fixed to 0 after the automatic level adjustment. It can be adjusted from -9 to +10
to get a level between 81 to 100 dBμV (see "General UHF level setting").
- The level of each cluster can be adjusted independently (see "manually level setting).
IMPORTANT : the 10 LEDs indication will not be changed after setting the levels manually.
