1. Einleitung
The Behringer DUAL-PHASE is an authentic analog dual-phase shifter pedal designed to recreate the classic 70s phaser sound. Utilizing 12 optocouplers, this pedal delivers a rich, intense, and natural phasing effect. It features two independent sweep generators and two phaser sections (A and B), offering extensive control over your sound. With CV control capabilities and a robust metal chassis, the DUAL-PHASE is a versatile addition to any musician's setup.
2. Sicherheitshinweise
- Stromversorgung: Use only a 9V DC, center-negative power adapter. Ensure the adapter provides sufficient current (at least 670mA, 1A recommended). Using an incorrect power supply can damage the unit and void the warranty.
- Feuchtigkeit: Do not expose the unit to rain, moisture, or any liquids.
- Belüftung: Sorgen Sie für ausreichende Belüftung rund um das Gerät. Blockieren Sie keine Belüftungsöffnungen.
- Reinigung: Clean the unit only with a dry, soft cloth. Do not use liquid cleaners or solvents.
- Platzierung: Place the unit on a stable, flat surface. Avoid extreme temperatures or direct sunlight.
- Wartung: Versuchen Sie nicht, dieses Gerät selbst zu reparieren. Überlassen Sie alle Wartungsarbeiten qualifiziertem Fachpersonal.

The DUAL-PHASE pedal features a comprehensive set of controls for shaping your phaser effects. Below is an overview of the front panel controls and rear panel connections.
3.1 Bedienelemente auf der Vorderseite

Figure 1: Behringer DUAL-PHASE Analog Phaser Pedal - Front Panel Overview
- 1. SWEEP GENERATOR 1: Controls for the first sweep generator.
- RATE: Adjusts the speed of the phaser sweep for Generator 1.
- FORM: Selects the waveform shape for the sweep (e.g., sine, triangle).
- LEBENSLAUF: Switch to enable external Control Voltage input for Generator 1 rate control.

Figure 2: Close-up of Sweep Generator 1 controls (RATE, SHAPE, CV switch).
- 2. PHASOR A: Controls for the first phaser section.
- TIEFE: Adjusts the intensity or range of the phasing effect for Phasor A.
- RÜCKMELDUNG: Controls the amount of phased signal fed back into the input, creating more resonant and intense effects.
- 3. SWEEP GENERATOR 2: Controls for the second sweep generator.
- RATE: Adjusts the speed of the phaser sweep for Generator 2.
- FORM: Selects the waveform shape for the sweep.
- 4. PHASOR B: Controls for the second phaser section.
- TIEFE: Adjusts the intensity or range of the phasing effect for Phasor B.
- RÜCKMELDUNG: Controls the amount of phased signal fed back into the input for Phasor B.
- 5. SWEEP SYNC: Controls for synchronizing and blending the sweep generators.
- NORM/REV Switch: Changes the phase relationship between the two sweep generators.
- GEN 1/GEN 2 Switch: Selects which generator controls the overall sweep.
- SWEEP Knob: Blends the output of the two sweep generators.
- 6. PHASOR B INPUT (IN A/D Switch): Determines the input source for Phasor B. When set to 'IN A', Phasor B receives its input from the output of Phasor A, creating a series effect. When set to 'D', Phasor B receives a direct input, allowing for parallel processing or dual-channel use.
- 7. Footswitches (A & B): Engage or bypass the respective phaser sections.
3.2 Anschlüsse auf der Rückseite
The rear panel typically includes the following connections:
- EINGANG: 1/4" TS jack for connecting your instrument or audio source.
- AUSGABE: 1/4" TS jack for connecting to an ampVerstärker oder nächstes Effektpedal.
- LEISTUNGSEINGANG: 9V DC input for connecting the power adapter.
- CV INPUT: 1/4" TS jack for external 5V Control Voltage input to modulate parameters.
4. Einrichtung
- Stromanschluss: Connect a 9V DC, center-negative power adapter (minimum 670mA, 1A recommended) to the POWER INPUT jack on the rear panel.
- Audioeingang: Connect your instrument (e.g., guitar) or audio source to the INPUT jack using a standard 1/4" TS instrument cable.
- Audioausgang: Verbinden Sie die OUTPUT-Buchse mit Ihrem amplifier, mixer, or the input of another effect pedal using a standard 1/4" TS instrument cable.
- CV Control (Optional): If using external CV control, connect a 5V Control Voltage source to the CV INPUT jack. Ensure the CV switch for the desired sweep generator is engaged.
- Anfangseinstellungen: For a basic phaser effect, set all DEPTH and FEEDBACK knobs to mid-range (5), and adjust the RATE and SHAPE knobs on Sweep Generator 1 to your preference. Ensure the PHASOR B INPUT switch is set to 'IN A' for a combined effect, or 'D' for independent operation.
5. Bedienungsanleitung
The DUAL-PHASE offers a wide range of phasing effects. Experiment with the controls to discover its full potential.
- Den Effekt aktivieren: Press the A footswitch to engage Phasor A. Press the B footswitch to engage Phasor B. The corresponding LED will illuminate when active.
- Adjusting Sweep Speed: Use the RATE knobs on SWEEP GENERATOR 1 and SWEEP GENERATOR 2 to control the speed of the phaser sweep.
- Changing Sweep Shape: The SHAPE switches allow you to select different waveform shapes for the sweep, altering the character of the modulation.
- Controlling Effect Intensity: The DEPTH knobs for PHASOR A and PHASOR B adjust how pronounced the phasing effect is. Higher settings result in a deeper, more dramatic sweep.
- Adding Resonance: The FEEDBACK knobs for PHASOR A and PHASOR B introduce a portion of the output signal back into the input, creating a more resonant,
