Behringer 130 DUAL VCA - Legendary Analog Dual ...

Behringer 130 DUAL VCA - the legendary dual VCA module for Eurorack modular synthesizers The Behringer 130 DUAL VCA is a dual-channel voltage-controlled amplifier (VCA) module designed for the Eurorack system. It is an authentic reproduction of the original circuitry from the System 100M synthesizer of the 1980s, adapted for installation in a standard Eurorack case. Product Features The module offers a range of professional features that distinguish it from other VCA modules available on the market: Two independent VCA channels - each with its own set of inputs, outputs, and controls Three signal inputs (Sig In) per VCA (3.5 mm jack) with individual gain controls and a built-in three-channel mixer Manual gain control (initial gain) - useful when working with bidirectional modulation signals, such as LFOs Dual outputs - Low and High - Low output for connecting guitar amplifiers and mixers; High output for line-level inputs Signal and clip indicators - allow for real-time level monitoring Linear or exponential characteristic switch - enables precise matching of the amplifier's response to envelope generators and volume controls Mod In inputs with dedicated controls - allow shaping the waveforms of Sig In signals using signals from other modules Faithful reproduction of System 100M circuitry from the 1980s Eurorack format - compatible with any standard modular case Professional Sound Shaping Capabilities The Behringer 130 DUAL VCA module is an incredibly versatile tool in the arsenal of every modular synthesizer user. Thanks to two fully independent VCA sections, each channel can operate completely separately, allowing simultaneous processing of two independent audio signals. Each VCA is equipped with three Sig In signal inputs with individual gain controls, enabling the mixing of up to three sound sources directly within the module. This eliminates the need for an additional mixer to combine oscillators or other signal sources. A key advantage of this module is the ability to switch the output characteristic between linear and exponential modes. The linear characteristic ensures a proportional response to control voltage changes, making it ideal for working with constant-amplitude control signals. The exponential characteristic, on the other hand, works perfectly with envelope generators, providing more natural and organic responses to voltage changes—particularly useful for shaping sound dynamics and controlling volume. The Behringer 130 DUAL VCA module also features a unique initial gain function, which allows the amplifier to be opened independently of the control signal. This is extremely useful when working with bidirectional modulation signals, such as low-frequency oscillators (LFOs), which oscillate across both positive and negative voltage values. Built-in signal and clip indicators enable precise level monitoring, preventing unwanted sound distortion. The Mod In inputs, equipped with their own modulation depth controls, open up additional creative possibilities. They allow signals from other synthesizer modules—such as waveform generators, LFOs, or envelopes—to be introduced for dynamic shaping of Sig In waveforms. This transforms the module from a simple amplifier into a powerful tool for modulation and creating complex sounds. Applications Volume and dynamics control of audio signals in a modular synthesizer Mixing up to three signal sources in each of the two independent channels Envelope control for shaping sound dynamics Waveform modulation using LFOs and other control signals Connecting the Low output to guitar amplifiers, mixers, and effect pedals Connecting the High output to line inputs of mixers, audio interfaces, and active monitors Expanding an existing Eurorack module setup Starting your journey with a modular synthesizer Detailed Technical Specifications Format: Eurorack Type: Dual VCA (dual-channel voltage-controlled amplifier) Signal Inputs: 3x Sig In per VCA (3.5 mm jack) Modulation Inputs: Mod In with dedicated depth controls (3.5 mm jack) Outputs: Low output and High output per channel Output Characteristic Switch: Linear / Exponential Indicators: Signal and Clip Dimensions: 129 x 81 x 44 mm (5.08 x 3.19 x 1.73 inches) Case Material: Metal Color: Black, Gray Materials and Construction The Behringer 130 DUAL VCA module is constructed from durable metal materials, ensuring structural solidity and resistance to mechanical damage during installation in a Eurorack case. The front panel features precise craftsmanship with clear labeling of all controls and jacks. The ergonomic placement of knobs, switches, and jacks ensures comfortable operation even in densely packed modular systems. The metal construction also provides effective shielding against electromagnetic interference, resulting in a clean processed signal.
