Filter
Notation
Definition
All-pass filter
apf [Q<q>] [< frequency>Hz|kHz ]
Defines an all-pass filter. When Q is set, an all-pass filter
2
nd
order is implemented
Bank
bank "<labeling>"
Defines the preset bank. For each bank the same number
of presets must be programmed
Preset
preset "<labeling>"
Defines a preset which includes the loudspeaker data for
the two outputs
Channel selection
out 1|out 2
Selects the DSP- and amp channel Out 1 or Out 2
Comment
# <text>
The text following the pound sign is ignored by the DSP
Delay
delay <time>ms
Sets the time delay in milliseconds
Level
gain <value>dB
Increase or decrease of the level of the channel
High-pass filter
hpf [characteristic] [< frequency>Hz|kHz]
Defines a high-pass filter with selectable characteristic
(Butterworth, Bessel or Linkwitz-Riley with different
selectable slew rate) at a certain frequency
Low-pass filter
lpf [characteristic] [< frequency>Hz|kHz]
Defines a low-pass filter with selectable characteristic
(Butterworth, Bessel or Linkwitz-Riley with different
selectable slew rate) at a certain frequency
High-Shelf
hshelf [6/12] [< frequency>Hz|kHz] [<gain>dB]
Defines a high frequency shelving filter. The frequency
defines the middle of the filter
Low-Shelf
lshelf [6/12] [< frequency>Hz|kHz] [<gain>dB]
Defines a low frequency shelving filter. The frequency
defines the middle of the filter
Parametric EQ
Peq [Q<q>] [< frequency>Hz|kHz] [<gain>dB]
Defines a parametric EQ with frequency, Q factor and
gain
Polarity
phase nor / rev
Defines the polarity of the channel
Limiter
power [<impedance>R] [<thermal power>W]
[<peak power>W] [<amp-gain>dB]
Sets limiter values for the selected DSP channel
Release time
releasetime <time>ms
Sets the release time of the limiters
RMS time
rmstime <time>ms
Sets the averaging time of the RMS measurement for the
limiter
Peak time
peaktime <time>ms
Sets the averaging time of the peak measurement for the
limiter
Volume-Control
volcontrol
Defines the DSP- or amp channel which whose volume
can be set on the operation panel
