  • Page 3 Introduction The Centaur’s Gates is a fully analog signal path dual multitype gate. Each of its two channels can take many forms : a smooth and warm two-pole filter, a ready to ping low-pass gate (LPG), a VCA with a distorting feedback loop, or an aggressive filter reminiscent of the infamous Korg MS20.
  • Page 4: Installation

    Installation The Centaur’s Gates requires a standard 2x8 pin eurorack power cable. Make sure that the red stripe on the cable matches the -12V side of the Centaur’s Gates power header. Basics Both channels of the Centaur’s Gates have an audio input and output. Those inputs and outputs are normalized as described in the serial/pa- rallel chapter of this guide.
  • Page 5 Frequency/Level The frequency/level parameter adjusts the frequency of the filter or the level of the LPG/VCA. This parameter can be controlled with the frequency/level potentiometer and via the frequency/level CV input [J]. Additionaly, a dedicated CV input and potentio- meter allow for attenuation of the CV signal.
  • Page 6 CV Normalization & Link By default, CV2 input is normalized to CV1 input [M1]. This [M2] means that the signal received into CV1 input is sent to CV2 [M1] input when nothing is inserted into it. The Centaur’s Gates has [M2] a link function which allows the first channel controls to be added to the controls of the second channel.
  • Page 7 Gain The input gain LEDs and buttons set the input gain to one of the 3 values: -5dB, 0dB and drive. Reducing the gain to -5dB changes the filter's sounds, and gives the green style filters a softer and more liquid sound.
  • Page 8: Options Menu

    Options Menu The options menu allows to enable (or disable) Select Bus, clickless type switching, and sets the LPG frequency response. To enter the option menu, press in 1 & in 2 buttons together for 4 seconds. [I1&I2] To exit the options menu and save changes, press the in 1 button [I1]. To exit the options menu without saving, press the in 2 button [I2].
  • Page 9 Applications & Patch Examples Low-pass filter and VCA This is an obvious application using the two channels unlinked and in serial configuration. The first channel is set to low-pass filter, the second channel is set to VCA. Both channels are controlled from a single CV connection to CV1 input.
  • Page 10 Variable bandwidth four-pole band-pass filter The first channel is set to the green hi-pass filter, the second channel is set to the green low-pass filter, serial configuration and the link function are activated. The first channel’s frequency/level potentiome- ter controls the band-pass cut-off frequency, the second channel’s frequency/potentiometer controls the bandwidth (this potentiometer should be set at noon or higher).
  • Page 11 Notch filtering Set the first channel in low-pass filter mode and the second one in hi-pass filter mode. Turn on the link function, activate the parallel configuration and use only the second channel’s output while sending the signal into the first channel’s input. This configuration sums a low-pass filter and a hi-pass filter, resulting in a notch.
