Signal flow¶
The diagram below is a simplified representation of the signal flow through the miniDSP SHD:
The audio signal in the diagram flows from left to right:
-
One of the seven stereo input sources is selected by the user. The per-input volume offset gains are applied to the input channels at this stage.
-
The selected input signal is passed through stereo Dirac Live processing.
-
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.
-
Each output channel runs a comprehensive set of DSP functions: parametric EQ, crossovers, delay, output gain and compressor.
-
Finally, the master volume control is applied and output levels are captured for display in Device Console.
The combination of the routing matrix and the crossover blocks on the output channels is what gives the miniDSP SHD the ability to be used in many different system configurations.
Tip
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.
