The Behringer DW400 Dynamic Wah Pedal User Manual explains functions, controls, technical specs, safety and warranty information.
This manual introduces the BEHRINGER DYNAMIC WAH DW400 digital delay effect pedal, describing its various wah modes, human‑voice mode, and tempo‑auto‑wah function. It details the operation controls such as MODE, SENS, MANUAL, DECAY, and the EXP/CTL expression pedal input, as well as the input and output jacks for guitar, bass, and external footswitches.
The document also provides technical specifications (impedances, power requirements, dimensions, weight), safety guidelines, battery information, and warranty instructions. It notes that the pedal has no dedicated on/off switch—plugging into the IN jack powers the unit—and offers guidance for battery replacement and troubleshooting. This manual is written in Chinese.

Press and hold the footswitch for about 2 seconds; the LED will flash and the tempo mode becomes active, allowing you to set the auto‑wah speed with the footswitch.
