Befaco Atte Quad AttenuaTor/Inverter Module

Gain precise control over audio and control voltage signals with this compact four-channel Eurorack utility module. Each channel can attenuate an incoming signal from unity gain down to zero or invert it for negative attenuation, making it useful for adjusting modulation depth, changing signal polarity, scaling audio levels, and creating custom control voltages.

The cascaded input design automatically routes a signal from one channel to the next when the following inputs are left unpatched, allowing a single source to be distributed across multiple independently controlled outputs. With no signal connected, the first channel receives a normalized 10V source, letting the module operate as a flexible offset and manual voltage generator.

Individual inversion switches provide fast polarity changes, while four LEDs display the level and polarity of each output. Its precise zero position and compact 4HP format make it a practical addition to almost any Eurorack system.
