Behringer 921A Oscillator Driver Eurorack Module

Description

Behringer 921A Oscillator Driver Eurorack Module

Behringer 921A Oscillator Driver is an analog control module designed for Eurorack modular synthesizer systems. It enables centralized frequency and pulse width control for multiple oscillator modules within a modular setup. This makes it ideal for Eurorack systems where coordinated control of several oscillators is required.

The module operates as a control driver that distributes control voltage signals to connected oscillator modules. It provides summed control voltage inputs and high current outputs for frequency and pulse width modulation routing.

Within a modular system, it can manage multiple oscillator modules operating in parallel. Its switching and control functions allow tuning adjustments and pulse width management across connected oscillators in a patch.
