Once the DDRC-88D has been configured, the plugin is no longer required, as source and preset selection can be
done with the front panel or a remote control (see pages 38 and 39). If desired, however, the user interface can
remain online during use for real-
time (“live”)
adjustment of the settings.

IGNAL FLOW
The signal flow diagram of the DDRC-88BM when in enhanced/bass management mode is shown in the diagram
below.
LFE Mgt
The eight input channels are each routed to a low pass filter and summed to provide the
subwoofer signal. In addition, each channel is optionally high pass filtered.
Routing (pre-Dirac)
The eight high pass filtered channels and the subwoofer signal are routed into a 9-into-8 matrix
mixer. Each input signal to this block can be mixed at any level to each output.
Dirac
The DRC block implements the Dirac Live room correction algorithm. Dirac Live is configured
with the separate program
Dirac Live Calibration Tool for miniDSP
. This tab will show the level
and delay that Dirac Live has assigned to each channel. See page 18.
Mixer (post-Dirac)
A second matrix mixer (8-into-8) routes the Dirac Live output signals to the output channels. This
enables arbitrary mixing of room-corrected signals to output channels.
Outputs
Each output channel has a full suite of miniDSP’s audio processing functionality, including
parametric EQ, high/low (crossover) filters, gain and delay.
