Signal flow

The diagram below is a simplified representation of the signal flow through the miniDSP SHD Power:

The audio signal in the diagram flows from left to right:

  1. One of the five stereo input sources is selected by the user.

  2. The selected input signal is passed through stereo Dirac Live processing.

  3. The processed input channels are fed into a 2-in 4-out routing matrix that routes/mixes the two processed input channels to the four output channels.

  4. Each output channel runs a comprehensive set of DSP functions: parametric EQ, crossovers, level metering, delay, output gain and compressor.

  5. Output channels 1 and 2 are passed through the internal power amplifier.


When using Dirac Live, first set up the matrix mixer and the output channel crossovers using the miniDSP Device Console. Then in the Dirac Live app, export the generated filters into the same-numbered slot. For example, if you set up preset 2 in DC, export the filter in Dirac Live to slot 2.
