Routing Options and Processing Blocks
Due to the completely new DSP platform, the routing possibilities within the DSP-4080 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.
