8. Operation
All these software parameters must be set directly on the hardware device in the first
instance. The names of the menu points refer to the user navigation on the device.

Preset:
Delay
[adjust delay from 0 – 400m for each channel, in 1 cm steps]
Output Phase
[adjust output phase for each channel; choose between 0° or 180°]
Equalizer 1+6
[adjust equalizer per channel]
Frequency
Q
(bandwidth)
Gain
Shape
Parametric / Shelf
[fully parametrical EQ or Shelf-function]
With this digital filter you can affect the frequency range by making adjustments of filter
frequency (center frequency), the gain (boost resp. cut) and the Q-factor (bandwidth). If you
adjust the sensitivity (gain) to 0 dB you deactivate this filter. If you choose the type “Low Shelf or
High Shelf” the bandwidth is not activated (you can enter a value for the Q-factor but it is
ignored)!
You can use the equalizer 1 as a fully parametrical equalizer or as „Low Shelf“and the equalizer
6 also as fully parametrical equalizer or as „High Shelf“.
Equalizer 2- 5
[adjust equalizer per channel]
Frequency
Q
(bandwidth)
Gain
With this digital filter you can affect the frequency range by making adjustments of filter
frequency (center frequency), the gain (boost resp. cut) and the Q-factor (bandwidth). If you
adjust the sensitivity (gain) to 0 dB you deactivate this filter.
Crossover
(high pass- / low pass filter)
[crossover function per channel]
HP Frequency
Type
(subsonic-filter 12 dB Q=1,2 or 12 dB/octave or 24 dB/octave)
LP Frequency
Type
(off or 12 dB/octave or 24 dB/octave)
These digital filters (crossover) limit the frequency range. The high pass filter can not be
deactivated. When you need a full-range audio signal on the output you have to set the
frequency to 35 Hz and choose a type of the high pass filter.
Dynamics
[adjust dynamics per channel]
Threshold
Attack
Release
Post Gain
This dynamic processor is working when the audio signal exceeds the entered threshold-value.
The two time constants attack and release time draw the speed of the gain regulation
mechanism and are dependent to the program material. With the post gain you can adjust your
audio signal level.
Routing
[routing possibilities for each channel]
A/d1(L), B/d2(L), C/d1(R), D/d2(R), C always, D always,
A+B/d1(L+R), C+D/d2(L+R), C+D always, B+C+D, A+B+C+D/d1+d2
The routing of the DA 428 offers comprehensive possibilities for controlling the audio signal.
You will find detailed information in the table on page 11.
