All parameters are set with the rotary button.
Each function and parameters are shown on 2 digits display and different LEDs.
Programming
OPERATION
Enter programming mode
- Make all the necessary connections and connect the equalizer to the mains.
The software version is displayed
followed by a dot.
- Push on the rotary button for more than 3 seconds to enter into programming
mode.
‐Turn the button to select the desired mode.
‐Push the rotary button to enter the selected mode.
The LED is now RED colored
‐Inside the mode, turn the button to select the parameter (input, cluster, level,…)
Display
‐Push the button to confirm the parameter setting.
LED returns to a GREEN color.
Repeatthisselectiontosetallparameters.

Note : the equalizer will go in ‘stand-by’ and will display a dot after 1 minute if the rotary /
push button is not activated.
Setting clusters / UHF Input
The equalizer has 2 UHF inputs which are splitted over 8 clusters.
There are three possible configurations :
Input UHF 1 UHF 2
Number of
Cluster (s) 8 0
7 1
5 3
Exit programming mode
- Turn the button to select Exit mode.
The LED is green.
- Push the button to confirm.
A dot is displayed.
CLUSTER PROGRAMMING
UHF 1 clusters are indicated by the RED LEDs
n°. 1, 2, 3, 4, 5, 6, 7 and 8.
UHF 2 clusters are indicated by the GREEN LEDs n° 6, 7 and 8
