Signal Routing: Using Send and Return
The internal signal routing of the DLD and its normal connections provide a good set of capabilities of many uses. Variations
on the internal routing can be accomplished with simple patches at the front panel as well.
The
Send
and
Return
jacks of each of the two delay channels are simple in function, but offer a wealth of possibilities for
creative patching.
•
Send A and Send B:
The two
Send
outputs simply carry the delayed signal, unmixed with the input. It’s the same as
the main
Out
jacks if the
Mix
control is set fully clockwise — except that it’s always that way!
•
Return A and Return B:
The Return inputs are summed with the corresponding main
In
(A or B). However, they do
not appear in the “Dry” signal and are not attenuated by the
Delay Feed
knob and CV. This provides a rudimentary
input mix capability and a flexible signal routing for both external patching and variations on the unit’s basic signal
paths.
Cascading Delay
If you want to route the delays in series (cascade) with the output of Channel A
feeding the input of delay B, simply connect a single patch cord between
Send A
and
In B
as shown on the left. Controls of Channels A and B can be set
independently for a variety of effects. You can also monitor the
Out A
jack and use
the
Mix A
knob to blend between the dry signal and Channel A's delay.
Reverb-y echo room
Patch as shown on the left. Try setting one channel's
Time
to a fast delay such as
“1” with the
Time switch
flipped to 1/8. Set the other
Time
to a slow delay such as
“8”. Set both channel's feedback amounts to around 75%-90%. Take the output from
Out B
. Tap a very fast tempo (as fast as your finger will go!)
While this is not a true reverb effect, the combination of two delay speeds plus high
feedback results in a similar effect. Try modulating the
Time A
or
B
with CV, and try
pushing
Feedback
right to the edge!
Dual-input Cascading Delay
A variant on the previous patch is to connect
Send A
into
Return B
. The
principal advantage of this is that you can input another signal into the main
In B
while also taking feed from a separate source in
In A
. In the case that no
plug is inserted in
In B
, all you will be doing is adding an additional portion of
Channel A out in the input mix of Channel B. See the patch above (the input
and output signals are made explicit). In this configuration, both channels will
process
In A,
while
In B
is processed only by Channel B.
Feedback from Channel B to A
You can incorporate feedback from Channel
B back to A and thus through the whole chain
by putting a patch cord between
Send B
and
Return A
, as shown on the right. This
configuration is generally stable, but high
levels of feedback on both delays at the same
time could run out of control.
