Behringer 2600 VCO Eurorack Analog Oscillator Module

The Behringer 2600-VCO is a Eurorack-format analog oscillator module based on the classic oscillator design used in the legendary ARP 2600 synthesizer. Designed for modular synthesizer systems, it provides authentic vintage oscillator behavior while integrating seamlessly into modern Eurorack setups. With multiple simultaneous waveform outputs and extensive control options, the module enables a wide range of sound design possibilities.

The oscillator generates four simultaneous waveforms including sine, triangle, saw, and pulse, each available through dedicated outputs for flexible patching. The module supports wide frequency ranges covering both audio-rate and low-frequency operation, making it suitable for both tone generation and modulation duties within modular systems.

Multiple CV inputs allow precise pitch control and pulse-width modulation, while manual controls provide immediate access to core parameters. With its compact Eurorack format and faithful circuit design, the Behringer 2600-VCO is ideal for musicians and modular enthusiasts seeking classic analog oscillator performance in a modern modular environment.
