The Noise Engineering Lapsus Os Silver is a 10HP Attenuator/Attenuverter & Off-Set Eurorack Module, with an LED Disaply. Each Channel can operate either Unipolar or Bipolar. If nothing is plugged into an Input, an Off-Set of +/- 5V is generated depending on the Fader position, which is output at 2x Outputs in parallel. If a signal is fed into the circuit via the X Socket, it is Attenuated or Inverted depending on the Fader position and Switch setting.
