The Algorithms and Their Parameters
• The main stereo inputs are sent into the Rvb block.
• The stereo output of the Rvb block is sent into the stereo inputs of the FX block.
• The stereo output of the FX block is sent to the main left and right outputs.

Routing
Useful Configurations
The Routing parameter provides continuously variable control of the FX and Rvb
effect routing: Rvb and FX in parallel, Rvb into FX (series) and FX into Rvb
(reverse series). This parameter has a range of 0–400. The value of this
parameter determines the routing/ordering of the stereo Rvb and FX effects. The
values 0, 100, 150, 200, 300, 400 correspond to specific configurations and are
labeled with text instead of numbers.
Routing Value Effects Routing
Parallel (0) Rvb and FX are parallel
Rvb into FX (100) Rvb outputs into FX inputs (series 1)
Parallel (200) Rvb and FX are parallel
FX into Rvb (300) FX outputs into Rvb inputs (series 2)
Parallel (400) Rvb and FX are parallel
Note that the routing value takes precedence over the Sends and Returns
values. For example, if Routing is set to Rvb into FX (100), no input signal is
routed directly to the FX inputs — and the Rvb outputs aren’t sent directly to the
PCM 81’s main outputs.
It is possible to arrange the stereo Rvb and FX inputs and outputs into a variety
of useful configurations by simply adjusting the Sends, Returns and Routing
parameters. The following illustrations show several of these configurations.
Each illustration contains a block diagram showing signal flow through the
Submixer, as well as the displayed values for the Sends, Returns, and Routing
parameters that will produce the configuration.
