Opal Eurorack Triple Switched Attenuverter Module

Nekyia Circuits Opal: Three Channels of Pure Control

The Opal is a high-utility module designed to significantly expand the control potential of your Eurorack system. Each of its three independent channels can attenuate, pass-thru, or invert an incoming signal with extreme precision. The integrated toggle switches allow for rapid mode changes—perfect for live performance—while the high-quality potentiometers ensure smooth voltage transitions. When no input is present, each channel normalizes to a stable DC offset, providing manual control for modules lacking onboard knobs. Opal is the ultimate solution for keeping your modulation organized and your signal paths optimized.

Key Features:

• Triple Attenuverter Architecture: Three separate processing paths for maximum utility in just 8HP.

• Switched Versatility: Dedicated switches for instant phase inversion or signal muting.

   

• Internal DC Offsetting: Generate reliable control voltages for biasing external parameters.

• Bipolar Signal Path: Precision handling of both unipolar and bipolar CV, as well as audio signals.

   

• Visual Monitoring: Tri-color LEDs provide real-time feedback on signal intensity and polarity.
