The diagram below shows the signal paths for a multitimbral setup or song. The rst two zones
(or tracks in Song Mode) are diagramed as an example (represented by dark lines.) The 14
additional available zones (or tracks in Song mode) are represented by gray lines (labeled as Etc.)
Notice that each Program has its own Insert Chain, but all Programs share the same two Aux
Chains:
DSP Units - Manage and Distribute Processor Power for Effects
Each Eect Chain is composed of an eect-box or a series of eect-boxes. Each eect-box uses a
certain amount of the PC3A’s eects processing power, represented as a number of “DSP units.”
The number of DSP units used by an eect-box or Chain reects how complex the eect’s
algorithm is—more complex eects require more processing power. You can use up to 16 DSP
units at a time shared between all eects (except Master eects, which don’t use any DSP units.)
See TheEectsEnablePage on page 9-4 for details on how the PC3A automatically manages the
usage of DSP units (the default behavior,) and how you can override this behavior and manually
manage usage of DSP units.
Aux Override
Normally, in Program mode the Aux Eects Chains are specied by the program on the current
channel—or, in Setup mode and Song mode, by the program on the specied Aux Eects
channel. Aux override allows you to audition and select a new Aux chain without editing a
program. In Eects mode, the Setup Editor, or Song mode, press the AUXFX1 or AUXFX2 soft
buttons to set overrides for Aux Chain selection and other Aux Eects parameters. The Chain
specied for the Aux override is used instead of the chain of the current channel (or instead of the
specied Aux Eects channel in Setup and Song mode.) Also, send levels and other parameters
normally specied within individual programs can be set to xed values on the Aux Override
pages. See The Aux 1 Override and Aux 2 Override Pages on page 9-5 for details.
