GETTING STARTED
1. Check the AC voltage before connecting the
plug. Choose the main supply for the sound sys-
tem with care. Do not share sockets or earthing
with light dimmers.
2. Run audio cables separately from dimmer wir-
ing, using balanced lines wherever possible. If
necessary, cross audio and lighting cables at 90o
right angles to minimize the possibility of inter-
ference. Keep unbalanced cabling as short as
possible.
3. Check your cables regularly and label each end
for easy identication.
4. Before switching on the main power, keep all
output rotary faders all the way down to prevent
damage or excessive noise caused by bad level
adjustment, wrong wiring, defective cables, or
bad connections.
5. Always turn on the DFX256 PRO before the
power amplier; turn off the DFX256 after turn-
ing off the amplier.
6. Always turn off the unit before connecting or dis-
connecting the unit to the power source.
7. Never use any solvents to clean the unit. Clean
it with a soft, dry cloth.

FRONT-PANEL DESCRIPTION
1. INPUT LEVEL CONTROL
The input level control sets the level going into the
DFX256. You should set the level so that Peak indi-
cators only ash RED occasionally.
2. MIX (DRY / WET) CONTROL
This control sets the balance between the unaffect-
ed signal coming through the inputs and the effects
being generated by the DFX256 i.e. the balance of
wet (effect) and dry (no effect) sounds. By keeping
the Mix somewhere in the center, a blend of dry and
wet signal can be achieved.
3. EFFECT MODES CHART
This chart shows you what 256 effect modes are in
the DFX256.
4. LED DISPLAY
This 7-segment display indicates the current effect
program in Program mode. When the display shows
the letter “C” ashing, this means either the right
or left input signals are too high and should be re-
duced.
5. PROGRAM SELECT KNOB
Turning this control will allow users to ‘preview’ the
different digital effects. Pushing it in will load the pre-
set. If this control is not pushed within a few seconds
of changing the effect, the DFX256 will automatically
revert back to the previously loaded effect. When
this control is held down for a few seconds, the digi-
tal effects b will be bypassed. Holding it down again
will reactivate the effects. When selecting the Tap
Delay effect (T1 - T6), pushing the Program Select
control will allow users to adjust the delay time. The
time between the nal two presses will be calculated
and used as the delay time.
6. OUTPUT LEVEL CONTROL
This rotary control sets the level going to the amplier
or mixer from the output of the DFX256.
7. POWER SWITCH
This switch turns the power of the DFX256 on/off.
When the power is off, the DFX256 will be in signal
bypass position automatically i.e. this feature allows
the direct signal to pass through the DFX256 even
when the power is not switched on.
8. SIGNAL INDICATORS
These 2 small LED indicators, located within the digital
effect display, show when either the left or right inputs
are receiving a signal (the left LED indicates when the
left input is receiving a signal, the right indicates when
the right receives a signal). When the LCD display
(above these indicators) ashes “C”, the signal in the
left or right channel is excessive (ie. clip), and should
be reduced to keep the audio’s integrity.
9. LOAD INDICATOR
This small LED indicator, located within the digital ef-
fect display, will ash when users are previewing dif-
ferent effects (when turning the program select knob).
When a new program is loaded, this LED will stop
ashing.

connected to this jack, you can use your foot to
switch the effect mute on/off (bypass).
12. OUTPUT (LEFT & RIGHT)

es such as the effects returns on a mixing console
or power amplier inputs.
13. INPUT (LEFT/MONO & RIGHT)
There are 1/4” phone jacks which connect to sourc-
es such as the effects sends of mixing consoles. For
