The Behringer 1004 oscillator Eurorack module brings back the classic analog sound of the 1970s in a compact format designed for today's Eurorack modular synths. With discrete transistor circuitry that replicates the original "System 2500" modules, it adds vintage character to your modular rig. The 1004 features dual oscillator cores to mix and match waveforms, creating complex and evolving sounds. Whether you're just starting out or looking to add an iconic analog voice, the 1004 oscillator module inspires sound design creativity.

Classic Discrete Transistor Circuitry for Vintage Analog Tone

The 1004 oscillator module uses discrete transistors rather than integrated circuits, replicating the design of early modular synths. This gives it a vibrant, organic sound with rich harmonics that brings back the classic analog tone of the first modular synths. The all-analog signal path and components add vintage character without the need for modeling. From warm, smooth tones to searing leads, the 1004 delivers the big, bold sound of the synthesizer legends.

Dual Oscillator Cores Allow Complex Waveform Mixing

Within the 1004 module, you'll find two independent oscillator cores. Using the three-position switches, you can invert the waveforms or turn them off entirely. With both oscillators active, you can mix and match waveforms to create more complex evolving tones. Having separate oscillators opens up creative options for modulation too. The 1004 makes it easy to design sounds with interest and depth.

Create Your Sound With Extensive Controls

The 1004 oscillator puts sound design control at your fingertips. Coarse and fine tuning knobs allow precise frequency adjustments over a wide range. Modulate pitch with the 1V/octave input or the two control voltage inputs. Adjust pulse width or mix amounts of the individual waveforms. You can even sync oscillator frequencies for effects. With its versatile controls, the 1004 brings out the modular advantage of creating patches to customize your own signature sounds.

Standard Eurorack Size Plays Well With Other Modules

Designed for Eurorack modular synth systems, the 1004 oscillator has the standard size for easy integration. Its power connector draws the needed electricity from your modular power supply. The 1004 provides two audio outputs to send its oscillators wherever you want in your system signal chain. Modulation inputs allow interfacing with other modules like envelopes and LFOs. Whether starting fresh or adding to an existing setup, the 1004 slots right in to become the vintage-flavored oscillator your modular rig needs.
