Navigation and Designing Crossovers
The DNA SC48 has 50 Drive Module preset locations. These can be stored and recalled from the
< INPUT > pages, for the channel being viewed. To design a new crossover, press the desired < INPUT >
or < OUTPUT > button to enter the pages where the parameters for each of the channels are shown.
Once in these pages the up <

> and down <

> buttons will scroll through the processing
parameters for the selected input/output. Pressing the < INPUT > or < OUTPUT > button repeatedly
will scroll through the channels. This allows the user to enter all the parameters for each of the
channels in the signal chain or enter each parameter for each channel one after another. A
parameter may be adjusted when it is displayed by turning one of the three parameter encoders
“
A
”, “
B
” or “
C
”.
Each of the three parameter encoders is associated with a zone on the display. Adjusting the
leftmost parameter encoder
“
A
”
will change the value of the parameter showing in the leftmost
zone of
the display above the “
A
” and so on. Turning an encoder clockwise will increase the value of
a parameter, or anticlockwise will decrease it. The encoders are velocity-sensitive so turning an
encoder rapidly will cause the action to ‘accelerate’, so th
e value changes more rapidly.
Note that the presence of an active overlay on one of these parameters is indicated by “[]” being
appended to the displayed parameter value
– e.g. “+2.6dB[]”.

Factory Module Presets
The device may contain a library of
Factory Presets
designed to suit a range of enclosures.
Factory Presets
may contain some parameters that are fixed and hidden from view; the remainder of
the parameters are available for user manipulation. The number and type of hidden parameters is
dependent on the Factory Preset, typically crossover frequencies, output delay and some EQs are
hidden; those settings that are a function of the loudspeaker cabinet design and should not require
adjustment for different applications.
Factory Presets
are locked (as indicated by a ‘box’ symbol after
the Preset name) so they cannot be over-written. The user can, however, store an edited version of
a Factory Preset in any free preset location.
In addition to the Factory Presets
the device may have further ‘
Skeleton Presets
’ which will help to
create new presets. They can be used to develop settings for any loudspeaker combination and are
recalled in the same way as the
Factory Presets
described above. These Presets are also usually
locked but the user can name and store their own edited versions in any free preset location.
