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
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.
