7. Polarity
The polarity of each output can be set to either "Normal" or "Invert".
OUT 1
Polarity
If a certain output is stereo linked, modifying the polarity of one output will also change the polarity of the
paired output.
To change the polarity setting, use the encoder wheel or the ◄ and ► keys.
8. Lower filter slope shape (Lo shape)
The DP300 offers the possibility to apply band-pass filters to each output. Each filter has a lower and an
upper cut-off frequency, with a specific filter slope shape which determines the filter shape.
Depending on the application, each user can choose the filter type and slope shape which best suits the
particular specifications of the sound system.
In this screen, the lower 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
Lo Shape
In this example a Linkwitz-Riley filter with a slope of 24dB/oct is applied to OUT 1.
To select the desired filter shape, use the encoder wheel or the ◄ and ► keys.
9. Lower cut-off frequency (Hi pass)
From this screen, the lower cut-off frequency of the high-pass filter can be adjusted.
