Ecler DP 300 Manuel Utilisateur page 28

The adjustment range goes from 15Hz to 16kHz, in 1/6 octave steps. If you try to introduce a value
above 16kHz, the text "Off" will appear, while if you try to set i below 15Hz, the text shown is "OUT".
You should consider that if you set the high-pass cut-off frequency above 16kHz, the output of this
channel will be muted, as this frequency is too high.
To adjust the cut-off frequency of the filter, use the encoder wheel or the ◄ and ► keys.
10. Upper filter slope shape (Hi shape)
From this screen, the upper filter slope shape can be chosen. Following options are available:
Butterworth 6dB/octave (But 6)
Butterworth 12dB/octave (But 12)
Butterworth 18dB/octave (But 18)
Butterworth 24dB/octave (But 24)
Linkwitz-Riley 12dB/octave (L-R 12)
Linkwitz-Riley 24dB/octave (L-R 24)
Linkwitz-Riley 48dB/octave (L-R 48)
Bessel 12dB/octave (Bes 12)
Bessel 24dB/octave (Bes 24)
OUT 1
Hi Shape
In this example a Linkwitz-Riley filter with a slope of 24dB/oct is applied to OUT1.
To select the desired filter shape, use the encoder wheel or the ◄ and ► keys.
11. Upper cut-off frequency (Lo pass)
From this screen, the upper cut-off frequency of the low-pass filter can be adjusted.
OUT 1
Hi pass
The adjustment range goes from 15Hz to 16kHz, in 1/6 octave steps. If you try to introduce a value
above 16kHz, the text "OUT" will appear.
To adjust the cut-off frequency of the filter, use the encoder wheel or the ◄ and ► keys.
