Thank you for showing your confidence in us by purchasing the BEHRINGER DYNAMIC WAH
DW400. This effects pedal delivers a variety of wah effects including a Human Voice mode
creating an unbelievable “talking” sound. Experience exciting new sounds!
Select the effect mode via the MODE switch:
UP: Creates a Wah effect. The filter moves
upwards (from low to high frequencies).
DOWN: Creates a Wah effect. The filter
moves downwards.
SYNTH: A stronger upward Wah effect with
a synth-like resonance filter sound.
HUMAN VOICE: Turns your instrument
signal into the sound of a human voice. The
sound alters between 2 selectable vowel
sounds and adds slight overdrive.
TEMPO: Auto Wah. Tap in the tempo via foot
or external foot switch.
SENS determines the effect sensitivity,
depending on the input level. In HUMAN
VOICE mode, it selects the first vowel. In
TEMPO mode, this control has no function.
The MANUAL control determines the wah
effects’ lowest frequency. In HUMAN
VOICE mode, it selects the second vowel.
In TEMPO mode, this control has no function.
The DECAY control determines how quickly
the filter is shifted. In TEMPO mode, you
can shape the LFO waveform from Sine
(MIN) to Square wave (MAX).

*Connect an expression pedal (e.g. the FCV100) to the EXP/CTL connector
The ¼" TRS EXP/CTL connector can be used to connect two different types of pedals:
Use an expression pedal for Wah pedal functionality (for all modes).
Use an external foot switch instead of the pedal foot switch (
(in TEMPO mode only).
) to tap in the effect time
Use the ¼" TS GTR IN connector to plug in a guitar. Use either input
Use the ¼" TS BASS IN connector to plug in a bass guitar. If you use this input, the filter
parameters are optimized for bass signals. With a cable in input
, this input has no function.
The ¼" TS OUT connector sends the signal to your amp or other effects devices.
The ON/BATT LED illuminates when the effect is activated. It also serves as a battery level
indicator. If the Tap function is active, the LED flashes.
Use the foot switch to activate/deactivate the effect. When pressing the foot switch 2 seconds
or longer, you can tap in the Auto Wah effect time (ON/BATT LED flashes).
Use the DC IN connection at the front of the unit to plug in a 9 V power supply (not included).
The BATTERY COMPARTMENT is located underneath the pedal cover. To install or replace the 9 V
battery (not included), press the hinges with a ballpoint pen and remove the pedal cover. Be careful
not to scratch the unit.
The DW400 has no On/Off switch. It is operable as soon as you insert a plug into the IN
connector. Disconnect the plug, if you don’t use the DW400. In doing so, you can
extend the life time of the battery.
The SERIAL NUMBER is located on the underside.
In rare cases interferences of the normal function may appear by external influence (e.g.
electrostatic discharge), as for example sound disturbances or malfunctions. If this
occurs, please turn down the volume on subsequent amplifiers and disconnect the
input connector briefly to restart the application.
