Section 2 - Getting Started
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:
nn
uu
Your
NaMe
Here
c

p~REU+ddl#fla
-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:
Output
..
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.
