Behringer 1004 OSCILLATOR MODULE – Analog Dual VCO Module for Eurorack

The Behringer 1004 OSCILLATOR MODULE is an authentic recreation of the legendary 2500 series VCO module from the 1970s, designed for modern Eurorack users. This dual-core analog oscillator delivers the warmth and character that defined the golden era of electronic music. With its wide frequency range, multiple waveforms, and extensive modulation capabilities, it’s an essential module for musicians, producers, and modular synthesis enthusiasts.

Key Features

✅ Classic dual-core analog VCO inspired by the ARP 2500 series from the 1970s.
✅ Authentic reproduction of discrete transistor circuitry delivering true vintage sound.
✅ Five selectable waveforms: sine, triangle, square, sawtooth, and pulse – mixable and reversible.
✅ Frequency range from 0.03 Hz to 16 kHz with switchable Low (LFO) and High (Audio) modes.
✅ Coarse and fine tuning with ±1 octave precision.
✅ Frequency and pulse width modulation with dedicated 1 V / octave inputs.
✅ Eurorack compatible – 16 HP width, easy to install and integrate with other modular components.

Analog Power and Creative Expression

The Behringer 1004 is not just a faithful recreation of the original but a versatile sound-shaping tool. With dual-core architecture and waveform switches, you can combine multiple shapes to produce harmonically rich tones and complex modulations. The discrete transistor design adds warmth and depth, reminiscent of classic synth tones by artists like Vangelis, Jean Michel Jarre, and Kraftwerk. Combine it with other 2500 series modules to craft immersive analog soundscapes or experimental modular setups.

Applications

The Behringer 1004 OSCILLATOR MODULE is ideal for professional Eurorack systems, home studios, and live performance rigs. It can function as both an audio oscillator and an LFO, enabling a wide range of sounds – from deep basses and rich leads to evolving textures and rhythmic modulations.
