Signal Routing Between Units
Depending of the current Config, the four units can be connected to each other in one of five
different ways, which are depicted with five different symbols. The routing symbols (shown
between each algorithm in Select Mode) are:

-7 -
Indicates a serial connection from the unit on the left into the unit on the right (our display
shows
Unit A
into
Unit B).
+ -
Indicates a parallel connection between the unit on the left and the unit on the right (our
display shows this between Unit B and Unit C).
.:..
"' = " - Indicates a feedback connection from the unit on the right back into the unit on the left
(our display shows Unit D back into Unit C).
* -
Indicates that the two units are" ganged together" using an algorithm that requires more
than one unit of processing power (for instance the Pitch Shift 2U algorithm). The routing
between units cannot be modified as long as such a "ganged" 2 Unit algorithm is active.
(blank space) - Indicates that there is no connection between units, and that they are routed
separately (the blank space will not appear in a 1 Source Config, because all four units are
always connected together).
Understanding Serial and Parallel Signal Routing
28
When we speak of connecting units together using the DP / 4's internal digital "patch bay," we are
usually referring to one of two types of signal routing, serial or parallel. To get the most out of the
DP / 4, it is
very
important to understand the difference between these two concepts.
• Serial routing means the input signal is routed through the first unit before being sent to the
input of the second unit.
This is
serial
signal routing between two units:

Signal
,.
If, for example,
the first unit is a chorus, and the second a reverb, you have the signal first
going through the chorus, then into the reverb. As a result you would hear the chorused
sound with reverb applied to it.
In the DP / 4, wherever units (or pairs of units) are connected together in series, the display
will show a
-7
symbol between the units.
