IGNAL FLOW
To understand how the C-
DSP 8x12 combines Dirac Live with miniDSP’s audio processing, refer to
Figure 5. Each
of the blue labels at the top of the diagram corresponds to a tab accessible in the plugin user interface.
The flow diagram represents:
•
Six analog input channels and one stereo digital pair are passed through bass management, to extract a
subwoofer channel (optional)
•
The signal is passed through a matrix mixer to route to eight channels of Dirac Live processing.
•
The Dirac Live outputs are fed into an 8-in 12-out matrix mixer.
•
The outputs from the mixer are processed via crossovers, parametric EQ, and gain and delay.
The signal processing is configured by two different programs
–
DLCT 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, both configurations are loaded into the working DSP memory.
Because of the way these two “halves” of the C
-
DSP 8x12 DL 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 plugin, acoustic measurement with a separate program like Room
EQ Wizard (REW) will give the best results. If you wish to use the advanced features of the C-DSP 8x12 DL and
are not familiar with acoustic measurement software, see Acoustic Measurement Primer on page 73.
