DO NOT REMOVE COVER (OR BACK)

NO USER SERVICEABLE PARTS INSIDE

REFER SERVICING TO QUALIFIED PERSONNEL

The lightning flash with arrowhead symbol, within an

equilateral triangle, is intended to alert the user to the

presence of uninsulated “dangerous voltage” within the

product’s enclosure that may be of sufficient

magnitude to constitute a risk of electric shock to persons

.

The

exclamation point within an equilateral triangle is in-

tended

to alert the user to the presence of important operat-

ing and maintenance (servicing) instructions in the literature

accompanying the appliance.

WARNING: To reduce the risk of fire or electric shock, do

not expose this apparatus to rain or moisture.

CAUTION: Use

of controls or adjustments or performance

of procedures other than those specified may result in

hazardous radiation exposure.

The apparatus shall not be exposed to dripping or splashing and that no objects filled with liquids, such as vases,
shall be placed on the apparatus. The MAINS plug is used as the disconnect device, the disconnect device shall
remain readily operable.

GETTING STARTED

1. Check the AC voltage before connecting the
plug. Choose the main supply for the sound sys­tem with care. Do not share sockets or earthing
with light dimmers.

2. Run audio cables separately from dimmer wir­ing, using balanced lines wherever possible. If
necessary, cross audio and lighting cables at 90o
right angles to minimize the possibility of inter­ference. 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 turn­ing off the amplier.

6. Always turn off the unit before connecting or dis­connecting 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 unaffect­ed 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 re­duced.

5. PROGRAM SELECT KNOB

Turning this control will allow users to ‘preview’ the
different digital effects. Pushing it in will load the pre­set. 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 digi­tal 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 ef­fect display, will ash when users are previewing dif­ferent effects (when turning the program select knob).
When a new program is loaded, this LED will stop

ashing.

REAR-PANEL DESCRIPTION

10. AC 10V IN INLET

The supplied AC Adapter is plugged into this con­nector.

11. FOOTSWITCH

This is a 1/4” stereo phone jack. If a foot switch is
connected to this jack, you can use your foot to
switch the effect mute on/off (bypass).

11

12. OUTPUT (LEFT & RIGHT)

There are 1/4” phone jacks which connect to devic­es 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 sourc­es such as the effects sends of mixing consoles. For
mono application, use the “Left/Mono” input.
