## Description

The **AttenuVerter** is a dual-channel CV processor for Eurorack modular systems. It allows you to attenuate, invert, and offset two independent control voltages — all in a compact 4 HP front panel.

Each channel features a dedicated offset potentiometer, giving you precise control over your CVs. A bi-color LED per channel provides instant visual feedback: green for a positive signal, red for a negative one, with brightness reflecting the signal strength. When the LED is off, the output is near 0 V.

##### Typical use cases:

* Scale the amount of CV sent to a VCF cutoff or VCA — from full pass-through (×1, fully clockwise) to full inversion (×−1, fully counter-clockwise)
* Reverse an LFO waveform (e.g. turn a rising ramp into a falling one)
* Add a DC offset to shift a CV up or down

##### What's in the box?
The PCB comes with all SMD components **pre-assembled**. You only need to solder a handful of through-hole parts:

* Power connector
* 2 bi-color LEDs
* Potentiometers
* Jack sockets

Assembly is straightforward and suitable for beginners.
