is
adopted
to
obtain

@Provided
with
three
output
jacks,
two
kinds
of
stereo
effects
are
selectable.
®The
Rhythm

function
makes
it
possible
to
synchronize
the
DE-200
with
any
rhythm
machine
featuring
a
trigger
out,
such
as
the
TR-606,

etc.
Also,
it
can
be
used
as
a
sampler.

Important Notes
®Be sure to use the voltage shown on the Name
Plate on the rear panel.
e@The DE-200 may genrate heat during operation,
this is quite a normal situation caused by AC power,
so there is nothing to worry about it.
Please never disassemble the DE-200 even if it
breaks down.
@\lf the DE-200 is not to be used for a tong period
of time, unpiug the cord from the socket.
Fixing to the 19”’ Rack
Use 5mm screws
®Please do not pull ,the cord but hold the plug when
unplugging.
@Piease avoid placing or dropping anything heavy on
the Power Cahel.
®Operating
the
DE-200
near
a
nean
or
fluorescent
lamp
may
cause
noise
interference.
If
so,
change
the
angle
of
the
DE-200.
®@Avoid using the DE-200 in extreme heat, humidity
or where it may be affected by dust.

@ Input Jack
Through this jack, signal is fed
from an external device such as a
musical instrument and mixer.
* This Input Jack has priority to another
input jack on the rear panel.
@ Bypass Switch with Bypass indicator
When the DE-200 is turned to the
Bypass mode, only direct sound is
sent out.
* This Bypass Switch is not mechanical,
therefore does not function when
the unit is turned off.
@ Input Level Control with the Input
Level indicator
This adjusts the input level
@ Delay Time Range Control
This switch selects any delay time
range among 9 options of 25 to
640ms,
© Delay Time Fine Control
This knob is to delicately change
the delay time set with the Delay
Time Range Control. !t is continuous-
ly variable from 0.5 to 1.0 times,
*By using above two controls @ and
© , it is possible to continuously alter
the delay time from 1.25 to 640 ms.
@ Mode Switch with Mode Indicator
This switch can double the delay
time which is set with the Delay Time
Range and the Delay Time Fine

5 Adjust the LFO frequency for modulation with
the Modulation Rate Control, and its depth
with the Depth Control.
*if the Depth Control is set to MAX, the Delay
Time set with the Delay Time Range Controi will
change between 0.5 to 7.0 times.
Adjust the feedback level with the Feedback Level
Control. {f it is set to MIN, single delay effect
will be obtained.
* if the Delay Time is set long {echo}, the repeat
number can be changed, and if it is short (flanger),
the resonance can be changed with this same knob.
*With the Feedback Phase Switch, feedback signal
can be inverted, therefore the flanger effect will
be emphasized.
7 Adjust the volume of the direct and the delay
sounds by the OUTPUT MIXER section.
* Usually, the Direct Level is to be set to MAX,
and only the Delay Level Control is to be changed.
{if the DE-200 is set up between the Echo Send
and Return of a mixer, or if the stereo effect of
2-@ is desired, set the Direct Level Cantroi to MIN
This is to obtain only Delay output.
*Both Output Jacks on the front and rear panel
can be simultaneously used.

Sample Note

Application
The DE-200 features a unique function called ‘’Rhy-
thym Sync” that is to start or resume the delay effect
by external trigger signal. This enables delay effect
finely synchronizing with the rhythum machine
you use. Also, by holding the sound you like, it can
be used as external sound source for the rhythm
machine.
A Synchronization with a Rhythm machine
You can obtain the Delay effect that finely matches
the programmed rhythm.
@
Connect
the
Rhythm
Sync
Jack
to
the
Trigger
Out
Jack
of
the
rhythm
machine.
Then
the
internal
systern
will
automatically
set
the
range
to
MAX
(640
ms)
regardless
of
the
position
of
the
Delay
Time
Range
Control
on
the
front
Panel.
® Set the Delay Time Fine Control to MAX {x 1.0).
®
If
you
are
to
play
quick
tempo
quarter
notes
or
eighth
to
16th
notes,
set
the
Mode
Switch
to
x
1,
and
for
slow
tempo
quarter
notes
or
half
to
whole
notes,
set
it
to
x
2.
Be
sure
that
the
trigger
cycle
does
not
exceed
the
maximum
delay
time.
@® | the feedback level is set ta MIN, you obtain the
single delay that is one note slower than the trigger
note set in the rhythm machine. {If the feedback
level is set to higher, echoes will be repeated at
the same timing as the set note. (If it is set to
quarter
note,
echoes
will
be
repeated
in
quarter
note interval, and if set to eighth note, in such
an interval.)
© Irregular repetition of echo effects can be obtain-
ed by setting irregular rhythm in the rhythm
machine. Also, if you have written rhythm
patterns in a programmable rhythm machine, the
echo effect can be automatically varied. (Preset
Memory of Delay Time}
Examples
B S. 0. §. (sound on sound) play by synchroniza-
tion with a rhythm machine
@ Repeat the same procedures as A @ 10@.
® Connect the Pedal Switch DP-2 to the Hold Jack
on the DE-200's rear panel. Then the Foot Switch
will work as the Hold Switch.
@ Set the Feedback Level Control to MAX. (lf
you wish to reduce the volume of the previous
sound, lower the same control).
®
While
pressing
the
Hold
Switch
down,
start
the
rhythm
machine.
© Releasing the DP-2 will start recording and press-
ing
it
will
playback
the
recorded
sound.
So
you
can
overdub
the
sounds
by
pressing
or
releasing
the
pedal.
The
previous
sound
will
remain
because
of
the
raised
feedback
Jevel.
If
you
are
to
start
all
over
again,
set
the
Feedback
to
MIN
to
erase
the previous sound.

Cc Using the DE-200 as an external sound source
for a rhythm machine.
Connect a rhythm machine (Trigger Out Jack}
and the OP-2 to the Rhythm Sync Jacks of the
DE-200.
Set the Delay Time Fine Contro! and Mode
Switch to appropriate position and mode. e.g.
for short time recording, set the Mode Switch
to "x1" (MAX 640ms). If you like a raised pitch
in playback, set the Fine Control to '’x1.0"' and
the Mode Switch to “x2” in recording, and to
lower the pitch, set the Fine Control! to “’x0.5”
and the Mode Switch to ‘x1’ in recording. (That
is, you Can move an octave up or down by change-
ing the Mode Switch.)
Set the Feedback Level Control to MIN if record-
ing just once, and set to MAX for overdubbing.
During sampling (recording), stop the rhythm
machine. The Foot Switch serves as a recording
start switch, so press the peda! to the sound to
be recorded in a right timing. (If you press it too
late, the head of the sound will be missed out,
and if too early, silence will be interfered, there-
fore there will be no rhythm synchronization
possible.) Repeat the same procedure for over-
dubbing.
If recording has been completed, turn on the
Hold Switch on the front pane! of the DE-200.
(Now it is turned to the playback mode.) Press-
ing the Foot Switch once again will playback
the recorded sound. If the recording is proved
unsatisfactory, turn the Hold Switch off and
strat fram the beginning.
f the recording is done satisfactory, start the
thythm machine, the recorded sound source will
play along with the programmed rhythm pattern.
With the Delay Time Fine Contro! and the Mode
and Modulation Switches, you can alter the
pitch and the tone color, and put vibrato effect.
< Notes for Rhythm Sync >
* Basically, the trigger cycle should be set within
the maximum delay time, but if it happens to
exceed it, it sounds like the delay time of such
jength.
* Plugging into the Rhythm Syne Jack will auto-
matically turn the DE-200 to the Rhythm Syne
mode. Thus, delay effect is not obtained unies
trigger signal is input.
*in the Rhythm Sync made, Delay Time Range is
automatically set to 640ms, therefore, the Delay
Range Switch in the front panel does not work.
The Delay Time Fine Control, however, works
as usual.
*The DE-200 does not adopt Battery Backup but
Dynamic Memory, so the sound you have recorded
will be retained only while the unit is turned on,
but erased on turning it off.
