Important notes
•Be sure to use the voltage shown on the Name Plate
on the rear panel.
•The SDE-1000 may generate heat during operation,
this is quite anormal situation caused by AC power,
so there is nothing to worry about it.
•Please never disassemble the SDE-1000 even if it
breaks down.
•if the SDE-1000 is not to be used for along period of
time, unplug the cord from the socket.
•Please do not puii the cord but hold the plug when
unplugging.
•Please avoid placing or dropping anything heavy on
the Power Cabie.
•Operating the SDE-1000 near aneon or fluorescent
lamp may cause noise interference. If so, change the
angle of the SDE-1000.
•Avoid using the SDE-1000 in extreme heat, humidity
or where it may be affected by dust.

lights up at its peak. (Distortion will start at
+12dB.) Even this knob is turned fully counter-
clockwise, the input fevel will not be zero.

(Note)
The SDE-1000 features battery back up system to
retain the memory even when switched off. The bat-

years. In this case, please have your local Roland
dealer do the job. (The first replacement might be
required before five years.)

(fj) Memory Channel Selector Switches with Memory
Channel Indicators
Four different panel settings can be written into
Memory. You can select any of the four Channels
just by pressing the switch. Delay Time, as well as
whether the Delay Range, DELAY PHASE, Modu-
lation and FEEDBACK Switches are on or off are
included in the panel setting to be written into
memory.
*Simply keep pressing arelevant Channel Switch for
about two seconds, and the Indicator of that
Channel Switch wii! flash showing that writing is
completed. If you just touch the switch, the existing
panel setting will be recalled.

©DELAY PHASE Switch with Delay Phase Indicator
With this switch, the Phase of the delay sound can
be inverted.

*The SDE-1000 remains muted for about seven
seconds even after turned on. Neither the direct or

(§: DELAY TIME Expanding Knob
Witn this knob, Delay Time can be increased up to
1.5 times (Normally, this should be set to "x 1"}.
*lf you use the instrument other than electric guitar
or bass, a beat may be caused. If so, rotate the
DELAY TIME Expanding Knob counterclockwise
until the beat stops.
*lf the Feedback Level is high, the SDE-1000 may
start oscillating at ahigh pitch. (If so, reduce the
-levei or rotate the DELAY TIME Expanding knob
counterclockwise until the oscillation stops.}
"When writing apanel setting or recalling it, set this
switch to the same level.
*ff setting such along delay that is impossible to set
in the "x 1"mode, the delay time later in use in the
"x 1" mode will not be longer than the maximum
deiay time of the "x 1"mode.
"When the Modulation Switch is set to on, rotating
the Delay Time Expanding Knob does not affect
the Delay Time Display,
*To see the current delay time, simply set the Modu-
lation Switch to the OFF position once.
(0> MODULATION FOOT CONTROL Jack
By connecting the Foot Control such as FV-200to
this jack, delay time can be controlled with the foot
pedal. Be sure to turn the Modulation Switch 1/
on, before starting control. The depth of the modu-
lation can be controlled with the MODULATION
DEPTH Knob©
SPreset Shift Jack
By connecting the Pedal Switch (DP-2) to this jack,
four preset panel settings can be sequencially called.
(2f PLAY MATE Jack
This is to connect to the Pedai Switch (DP-2). You
can set a Delay Time of any length just by pressing
the Pedai. The following shows the way to do that.
1.Connect the DP-2 to the PLAY MATE Jack.
2. Press the pedai, and the Delay Time Display will
show "0.0.0.0." (Stand-by mode}, and the Delay
Time Indicator remains dark (the Delay effect is
off).
3. Press the DP-2 twice, and the built-in computer sets
the Delay Time according to the interval between
the first pressing and the second.
4. If you press the Pedal once again, the DELAY TIME
Display shows "0.0.0.6." and the SDE-1000 is in
the Stand-by mode again.
•Please do not touch the MODULATION Switch or
DELAY TIME Expanding Knob during above pro-
cedures. Otherwise the accurate delay time may not
be obtained.
*The longest Delay Time you can set in the SDE-
1000 is 750ms, so if you happen to set the Delay
Tfme exceeding 750ms, the DELAY TIME Display
flashes showing the maximum Delay Time (750). In
such acase, press the DP-2 and set the Delay Time
again.
@HOLD Remote Jack
You can turn the Delay Hold function on or off by
connecting the Pedal Switch DP-2 to this jack. While
the Pedai is depressed, the sound will be repeated.
'This effect cannot be obtained if the delay time is
shorter than 20ms. When this function is being used,
the Memory Channel Selector (IT, the Deiay Time
Button @or Preset Shift Jack yfo': do not work.

(Notes)
In the following cases, delay sound is completely
muted, therefore, oniy the direct sound is heard.
1.When you change the deiay time;
The delay sound is muted as long as the DELAY
TIME Button is depressed, and still muted even
after the button is released until the SDE-1000 get
the stand-by mode.
*Here, the DELAY TIME Indicator does not light.
2. When recalling from Memory;
The delay sound is muted as long as the Delay Time
shown on the Display.
3. When the DELAY RANGE Switch is set to the "x

The delay sound is muted as long as the delay time
of the "x 1"mode.

-20dBm and -35dBm, i.e. it is designed to have
UNITY Gain (Input level: Output level =1:1). There-

devices whose rated input levels are equally —20dBm
