Modular Synth Module Behringer 130 DUAL VCA — dual voltage-controlled amplifiers

Behringer 130 DUAL VCA is a compact Eurorack-format module that provides two independent voltage-controlled amplifiers (VCAs) for precise level control of audio and control signals. Each channel accepts input and control voltage to shape amplitude dynamically, allowing envelope-following, modulation routing and mixing within modular synthesizer setups. The module is designed for integration into modular patches for both studio and live contexts, offering straightforward operation and reliable signal handling.

Advantages

The dual VCA design gives independent control over two channels, enabling parallel processing or stereo configurations without additional modules. The module supports both audio and CV signals, so the same controls can be used for dynamic amplitude shaping and modulation depth control. Its compact Eurorack form factor conserves rack space while maintaining standard control interfaces for fast patching and consistent signal behavior.

Suitable for

• Envelope-controlled amplitude shaping for synth voices
• Voltage-controlled mixing of audio and CV signals
• Stereo VCA chains and parallel processing in Eurorack systems
• Live performance patches requiring reliable level control
• Studio sound design and modulation routing

Key specifications

• Two independent voltage-controlled amplifier channels
• Eurorack-compatible module width and power requirements (standard format)
• Accepts both audio and control voltage inputs per channel
• Individual level control for each channel
• Signal mixing capability by summing outputs or using control voltages

How to use

Patch signal sources into the input jacks and route envelope generators or LFOs to the CV inputs to control amplitude. Adjust each channel's level control to set the baseline gain, then use incoming control voltages to modulate amplitude in real time. Combine outputs for mixing or route channels into further processing modules such as filters, effects, or mixers. The module operates as a flexible utility in both signal and control paths.

Usage recommendations

For consistent results, calibrate control voltages and check signal levels to avoid clipping. Use dedicated envelope generators for per-voice dynamics and reserve one channel for stereo panning or parallel processing when building more complex patches.
