Internal Design of the DTX700
In this reference section, you will find a description of
what takes place within the DTX700 between striking
of a pad and the output of sound from speakers.
Understanding how signals flow and are processed
internally will allow you to utilize the powerful func-
tions of this versatile instrument to their maximum
potential.
Pads & Trigger Signals
Whenever you strike a pad, a trigger signal containing various
items of performance data will be produced. These signals typi-
cally reflect the strength with which the pad was struck, the actual
location of the strike, and the like; furthermore, they are delivered
via a cable and a trigger input jack to the DTX700’s internal tone
generator, which outputs the appropriate drum sounds in response.
If a pad is set up to generate just one sound, there will be a one-to-
one relationship between the trigger signal type and the drum voice
output. With certain types of pad, however, it is possible to produce
a range of different types of trigger signal that reflect the location
of the strike, the drumming technique being used, and other factors.
[Terminology]
Zone:
The term “zone” is used to refer to specific areas of the pad,
such as the rim, cup, and head. Pads with multiple zones (such
as two- and three-zone pads) can produce a different trigger sig-
nal for each. As their name suggests, one-zone pads produce
only one signal irrespective of where they are struck.
Trigger input source:
Trigger input sources are named in accordance with the way in
which the corresponding pad or pedal is struck or operated.
One-zone pads (producing a single trigger sig-
nal)
A mono pad such as the TP65 Single Zone Drum Pad or
PCY65 Single Zone Cymbal Pad transmits only one type of
trigger signal to the DTX700, irrespective of where it is struck.
Two- and three-zone pads (producing multiple
trigger signals)
In contrast to the PCY65 Single Zone Cymbal Pad and other
mono pads, multi-zone pads such as the PCY65S Double Zone
Cymbal Pad can produce two different types of trigger signal
depending on the zone that is struck, while the PCY135 Triple
Zone Cymbal Pad can produce three. In specific terms, multi-
zone pads come in either the two-zone or three-zone variety.
For instance, the PCY135 Triple Zone Cymbal Pad illustrated
below comprises three trigger input sources – the bow, the
edge, and the cup – each of which generates a trigger input sig-
nal when struck.
