The crossover filters and EQs share DSP resources between two DSP chips. There are certain

assignment constraints, the table below summarizes how the resources are allocated.

* The EQ for outputs 3-6 may come from either DSP 1 or DSP 2, but DSP 2 filters are used first,

until all DSP 2 resources are allocated.

Summing this up in words:

 There are 18 filters in DSP 1, and 20 in DSP 2.

 All of the crossover filters for Outputs 1 & 2 come from DSP 1.

 All of the crossover filters for Outputs 3-6 come from DSP 2.

 All of the Input EQ comes from DSP 1.

 All of the Output EQ for Outputs 1 & 2 comes from DSP 1.

 Output EQ for Outputs 3-6 may come from either DSP.

Other notes:

 12dB/Octave crossovers use 1 filter per edge, except Linkwitz-Riley that uses 2.

 18, 24 & 36dB/Octave crossovers use 2 filters per edge.

 48 & 52dB/Octave crossovers use 4 filters per edge.

 Stereo EQs use 2 filters each.

For example, a stereo 3 way 12dB/octave crossover would use DSP resources as follows:

 4 filters are used in DSP 1 for Output 1 & 2 crossovers high edge crossovers. (2 per 12dB/

Octave Slope)

 12 filters used in DSP 2 for Output 3-6 crossovers. (1 per 12dB/Octave Slope)

 There is a total of (18-4)= 14 filters left in DSP 1 for either Input EQ or Outputs 1 & 2 EQ.

 There is a total of (20-12)= 8 filters left in DSP 2 for any Output EQ.
