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 90oright angles to mini-
mize the possibility of interference. Keep
unbalanced cabling as short as possible.
3. Check your cables regularly and label each
end for easy identification.
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 before the
power amplifier; turn off the DFX256 after
turning off the amplifier.
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.

2 PEAK (L/R) INDICATORS
They are bi-color LEDs. In most cases, they light up
green as “signal” LEDs, and will turn red when the
DFX256 is receiving a peak level signal. In general, a
few red flashes every now and then will not be a
problem. If the LEDs flash red very often or remain on
red, then reduce the input level control (1).

3 MIX (DRY / WET) CONTROL
This control sets the balance between the unaf-
fected 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.
4 LED DISPLAY
This 7-segment display indicates the current ef-
fect program in Program mode.
5 EFFECT MODES CHART
This chart shows you what 16 effect modes are
in the DFX256.
