Use the 

EDIT

 keys on each output channel with the 

BACK

 and 

NEXT 

keys to select the high 

pass filters, low pass filters, parametric equalisers etc.  Note that when designing a new 
crossover, the high and low pass filters will be set to default values.     
 
Use the 

EDIT

 keys on each input channel with the 

BACK

 and 

NEXT

 keys to select the gain, 

delay and parametric equalisers available on each input. 
 
Note that if no action is taken in menu mode, the unit will return to normal ‘default’ mode after 
about twenty seconds.  Repeat the above directions to return to menu mode.

13)  Routing Options and Processing Blocks

Due to the completely new DSP platform, the routing possibilities within the DX1.5 have been 
made completely flexible, with a matrix available allowing any combination of inputs to be 
routed to any output.  The additional DSP power has permitted the inclusion of more 
processing blocks, even considering the extra inputs and outputs, and the doubling of sample 
rate. 
 
To reduce set-up time and aid usability, several standard configurations are available as 
described in a later section. 
 
This section will outline the processing blocks available in relation to the signal path, and 
explain the various options for routing, including the “Free Assign” mode, which opens up 
completely flexible channel routing. 
 
The diagrams below show the processing available on inputs and outputs – ignoring matrix 
routing.

Preset Routing Configurations 

In addition to the ability to assign any combination of inputs to any output, a number of preset 
configurations are provided, for use when designing a crossover from scratch.  

These have the advantage of suggested settings for the high and low pass filters to useful 
basic starting points, to filter the different outputs as appropriate for the chosen configuration.  
These may be freely modified afterwards should they not suit the requirements exactly.
