The volume control on the Subwoofer signal also allows monitoring adjustments relative to
the L/C/R volume.
NOTE: You should start by matching the AMP and PROC overall volume levels on the screen
channels. Then match the surrounds and sub level to this reference to allow accurate A/B
comparisons.
4. Crossover
i. Screen DSP Settings
Left, Center and Right input channels are processed by a state-of-the-art DSP digital cros-
sover. All of the parameter settings are highly accurate, do not drift, and are repeatable from
unit to unit. These settings can be modified and stored in Configuration files and activated
using the Communications | Write Configuration to DCM command.
a Screen Signal Path
This shows a block diagram of the signal path through the different filters, delays, and
gain blocks. Select which channel you would like to view (L,LC,C,RC,R). Clicking on any
of the function blocks will cause the screen to jump directly to the appropriate area on
the Screen window. This is an easy method of finding the correct parameter to edit.
NOTE: There is no signal processing of the surround signal in a standard DCM, howev-
er, the DCM-2 & DCM-3 are "Active Surround Ready". Contact QSC if you need this
feature.
