Noise Engineering Sinc Defero
Buffered quad attenuator with LED signal indication
4 HP Eurorack module
Sinc Defero is a buffered quad attenuator with circular normaling, designed to solve the voltage drop issues of passive attenuators while providing visual feedback via bicolor LEDs. It allows a single CV or audio signal to be distributed and scaled across up to four independent buffered outputs, making it an essential utility for CV routing and level management in a modular system.
Features
- Quad buffered attenuator with four independent channels
- Circular normaling: Input 1 feeds all outputs unless overridden by plugging into subsequent inputs
- Bicolor LED indicators per channel showing incoming (In) and outgoing (Out) signal levels
- Green LED for positive voltage, red LED for negative voltage
- Fully counterclockwise attenuator position mutes the signal
- Rated for -10V to +10V input and output voltages
- Active buffered outputs prevent voltage drop present in passive attenuators
- 4HP compact form factor
- Reverse power protection
