Routing Options and Processing Blocks

Due to the completely new DSP platform, the routing possibilities within the 

DSP-2040

 has 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.

Input Channel Makeup

The diagram below shows the processing available on each of the four input channels, before routing to the 
matrix.

Output Channel Makeup

The diagram below shows the processing available on each of the eight output channels, after routing 

from the matrix.

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, of course, be freely modified afterwards 
should they not suit the requirements exactly.

The diagrams on the following pages show the connections made between inputs and outputs, and the 

suggested values chosen for the high and low pass filters.
