To understand how the Harmony DSP
8x12 combines Dirac Live with miniDSP’s audio processing, refer to
3. Each of the blue labels at the top of the diagram corresponds to a tab accessible in the plugin user interface.
From left to right:
•
Eight digital input channels are passed through bass management, to extract a subwoofer channel (optional)
•
A matrix mixer routes nine channels through to eight channels of Dirac Live processing.
•
The signals from Dirac Live are routed through an 8x12 matrix mixer to the 12 output channels.
•
Each output channel is processed with crossovers, parametric EQ, and gain and delay.
The signal processing is configured by two different programs
–
the
DiracLive
application for Dirac Live and the
C-DSP 8x12 DL plugin
for the processing on the input and output side of Dirac Live. Each program loads its
configuration into one of four presets or “slots”
. When a preset is selected, the configurations from both
programs are loaded into the working DSP memory.
Because of the way these two “halves” of the
Harmony DSP 8x12
work together, it’s usual to configure the
system from the outputs back to the inputs.
For the sections configured by the C-DSP 8x12 DL plugin, acoustic measurement with a separate program like
Room EQ Wizard (REW) will give the best results. (See the
