4. SET-UP
Pushing the rear encoder, it is possible to select the following three functions:
INPUT GAIN REDUCTION
SPEAKER DELAY SETTING
SELECTION OF A SPEAKER PRESET
Pushing once the rear encoder the GAIN REDUCTION LED will light up� Now rotating the encoder counter clockwise, it will be possible to reduce
the input gain� The gain reduction will be in steps of 0,1 dB for the first 10 dB and then in 1 dB steps� The maximum reduction is 99 dB�
Pushing a second time the rear encoder the DELAY LED will light up� Now rotating the encoder clockwise it will be possible to delay the signal
output of the speaker� The delay is expressed in meter� The delay will be in steps of 0,1 m for the first 10 m and then in 1 m steps� The maximum
delay will be 20 meter�
Pushing a third time the rear encoder the PRESET LED will light up� Now rotating the encoder clockwise it will be possible to select a preset:
EXTENDED LOW PRESETS (more extended and linear frequency response):
L1 30 Hz – 60 Hz L2 30 Hz – 80 Hz
L3 30 Hz – 100 Hz L4 30 Hz – 125 Hz
HARD PRESETS (less extended frequency response, more pressure at 50-60 Hz):
H1 40 Hz – 60 Hz H2 40 Hz – 80 Hz
H3 40 Hz – 100 Hz H4 40 Hz – 125 Hz
CARDIOID PRESETS (in combination with L presets)
C1 30 Hz – 60 Hz C2 30 Hz – 80 Hz
C3 30 Hz – 100 Hz C4 30 Hz – 125 Hz
SAVING A SPEAKER PRESET
After the parameter settings the two digits display will flash one time� This represent saving all the preset values in the speaker memory� Once saved,
all the speaker settings are permanent� It is possible to turn off and turn on; the speaker will remember the last settings�
CARDIOID SET-UP
It is possible to create subwoofer cardioid systems using groups of two or three modules�
A group of two modules shall be made as follow:
- Only use one of the L presets (30 Hz High Pass filter)
- 1 modules pointing in forward direction
- 1 module pointing in backward direction, correspondent cardioid preset
- The modules shall have the same settings (system delay, sensitivity, preset)
A group of three modules shall be made as follow:
- Only use one of the L presets (30 Hz High Pass filter)
- 2 modules pointing in forward direction
- 1 module pointing in backward direction, correspondent cardioid preset
- The modules shall have the same settings (system delay, preset)
- The 2 front modules shall have -1�5 dB gain less than the rear module�
