Behringer Ultra Flanger UF300 User Manual

2-Mode Flanger Effects Pedal

Thank you for showing your confidence in us by purchasing the BEHRINGER ULTRA FLANGER UF300. 

This high-quality effects pedal delivers two flangers in one—from jet-plane thick chorus, vibrato to 

short delay effects. Thanks to its high-performance features you can choose between classic and detuned 

flanger effects with extensive parameter controls for awesome sound shaping.
Originally, the flanger effect was generated with two tape recorders running synchronously. The same audio 

signal was recorded on both machines. If you put a finger on the left spool of one of the machines, the spool 

and the playback speed are slowed down. The generated delay results in phase shifting of the signals. 

(1) 

The MODE switch lets you choose between negative feedback (Mode 1) or positive feedback 

(Mode 2) flanger modes. Negative feedback means that the delayed signal is inverted before it is 

fed back to the original signal. In positive feedback mode the delayed signal is not inverted. In this 

case the effect has a more detuned character perfect for vibrato effects.

(2) 

With the MANUAL control you can adjust the flanger delay time. Longer delay times produce a 

sharper, more detuned sound, very close to a chorus effect.

(3) 

Turn up the DEPTH control to achieve a fuller and deeper effect sound.

(4) 

The RATE control determines the speed of the flanger effect.

(5) 

The RES(onance) control determines the amount of output signal fed back to the flanger input to 

increase the resonance frequency. That way the flanger effect gets more intensive.

(6) 

The ON/BATT LED illuminates when the effect is activated. It also serves as a battery level indicator.

(7) 

Use the footswitch to activate/deactivate the effect.

(8) 

Use this ¼" TS IN connector to plug in the instrument cable.

(9) 

The ¼" TS OUT connector sends the signal to your amp.

Use the DC IN connection at the front of the unit to plug in a 9 V power supply (not included).
