Behringer OSCILLATOR MODULE 1004 Dual Core VCO Module

Bring classic analog tone into your Eurorack with the Behringer OSCILLATOR MODULE 1004 Dual Core VCO Module. Based on the legendary 2500 series from the 1970s, this dual-core analog VCO delivers rich, musical waveforms with authentic discrete circuitry and versatile modulation options—perfect for building complex tones or foundational synth voices in your modular rig.

CLASSIC TONE GENERATION

The 1004 VCO features five waveform types—sine, triangle, square, sawtooth, and pulse—each accessible via three-position switches that allow for inverted, off, or normal phase output. Combine and shape multiple waveforms simultaneously for layered textures and evolving timbres.

WIDE FREQUENCY RANGE

Covering an impressive range from 0.03 Hz to 16 kHz, the oscillator can function as both a low-frequency modulator (LFO) or a high-frequency audio source, with selectable Low/High range settings. The coarse frequency control spans 10 octaves, while the fine-tune knob adjusts ±1 octave, giving you detailed control over tuning and modulation.

DYNAMIC MODULATION CONTROL

With two FM inputs (1V/Octave compatible) and pulse width modulation input, the 1004 is designed for expressive sound design. The pulse waveform width can be set manually or modulated dynamically—ideal for morphing textures or creating rhythmic interest.

EURORACK READY

The OSCILLATOR MODULE 1004 slots seamlessly into your Eurorack system. It occupies 16 HP of space and draws 60 mA at +12 V and 50 mA at -12 V. Just mount it with the included screws, connect the power cable, and start exploring everything from warm vintage leads to complex modulation signals.
