Behringer DUAL ENVELOPE GENERATOR MODULE 1003 – precise Eurorack envelope module inspired by the legendary System 2500

The Behringer DUAL ENVELOPE GENERATOR MODULE 1003 is an authentic recreation of the classic “System 2500” module from the 1970s, redesigned for modern Eurorack systems. Featuring two independent ADSR envelope generators, it enables the creation of deeply contoured sound shapes – from sharp percussive attacks to slowly evolving ambient textures. A must-have tool for electronic musicians, sound designers, and modular enthusiasts seeking analog expression and total creative control.

Product Features

• Two fully independent ADSR envelope generators in one module
• Authentic circuit design inspired by the original ARP 2500 system
• Full control over Attack, Decay, Sustain, and Release parameters
• Single and Multi Trigger modes for versatile performance
• Four outputs with selectable positive or negative polarity (±10V)
• Manual Gate buttons for hands-on envelope triggering
• TS 3.5 mm connectors compatible with all Eurorack systems
• Compact and lightweight – only 0.16 kg

Dynamic and expressive sound shaping

Each of the two envelope generators provides independent control over Attack, Decay, Sustain, and Release. This allows precise shaping of amplitude or modulation signals for any type of sound. Create punchy, percussive tones or long, evolving drones – the Behringer 1003 delivers flexibility and analog warmth in every setting. Its wide control range makes it ideal for electronic, ambient, cinematic, and experimental music production.

Flexible integration in any modular setup

The module fits perfectly into any Eurorack environment. It features Gate and Trigger inputs (TS 3.5 mm) for easy connection with external sources such as sequencers, keyboards, or other modules. Whether in studio setups or live performance rigs, the Behringer 1003 ensures precise synchronization and modulation control within your modular system.

Materials and build quality

Built into a compact and durable metal enclosure with the classic System 2500-style front panel, this module is both reliable and visually consistent with other Behringer modules. Measuring 42 x 81 x 129 mm (16HP width), it consumes just 40 mA (+12V) and 20 mA (-12V), ensuring efficient operation even in large modular setups.
