The Behringer FOUR PLAY is a high-performance quad Voltage Controlled Amplifier (VCA) and mixer module for Eurorack systems. Designed to be the "bread and butter" of any modular setup, it offers four independent channels that can process both audio and control voltage (CV) signals. With its cascaded inputs and outputs, it is as much a flexible utility mixer as it is a set of precision amplifiers.

• Four Independent VCAs: Each channel features a dedicated manual level control, CV attenuator, and bi-color LED for visual feedback on signal activity and polarity.

• Continuously Variable Response: Every channel includes a Curve control, allowing you to dial in the perfect response curve anywhere from fully exponential to fully linear.

• Cascaded I/O for Mixing: The module uses "normalled" connections, meaning that if you only patch into the final "4/MIX" output, the unit functions as a 4-channel voltage-controlled mixer.

• Integrated Boost Switches: Each VCA includes a dedicated +6 dB boost switch, ideal for bringing low-level signals up to Eurorack standard levels.

• DC-Coupled Circuitry: Fully capable of handling both audio signals and slow-moving CV signals (like LFOs or Envelopes) without signal degradation.
