Behringer Dynamic WAH DW400 User Manual

Thank you for showing your condence in us by purchasing the BEHRINGER DYNAMIC WAH DW400.
This eects pedal delivers a variety of wah eects including a Human Voice mode creating an
unbelievable “talking” sound. Experience exciting new sounds!
1. Controls
(1) Select the eect mode via the MODE switch:
UP: Creates a Wah eect. The lter moves
upwards (from low to high frequencies).
DOWN: Creates a Wah eect. The lter
moves downwards.
SYNTH: A stronger upward Wah eect with
a synth-like resonance lter 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 switch (10) or external foot switch.
(2) SENS determines the eect sensitivity,
depending on the input level. In HUMAN
VOICE mode, it selects the rst vowel.
In TEMPO mode, this control has
no function.
(3) The MANUAL control determines the wah
eects’ lowest frequency. In HUMAN VOICE mode, it selects the second vowel. In TEMPO mode,
this control has no function.
(4) The DECAY control determines how quickly the lter is shifted. In TEMPO mode, you can shape the
LFO wave form from Sine (min) to Square wave (max).
(5) The ¼" TRS EXP/CTL connector can be used to connect two dierent 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 ((10)) to tap in the eect time
(in Tempo mode only).
(6) Use the ¼" TS GTR IN connector to plug in a guitar. Use either input (6) or (7).
(7) Use the ¼" TS BASS IN connector to plug in a bass guitar. If you use this input, the lter parameters
are optimized for bass signals. With a cable in input (6), this input has no function.
(8) The ¼" TS OUT connector sends the signal to your amp or other eects devices.
