XAOC Devices Mińsk

M/S stereo width sculptor with dimension and depth

6 HP Eurorack module

Mińsk is a hybrid digital/analog stereo image processor for Eurorack that performs Mid/Side encoding and decoding, allowing independent treatment of the center and width components of a stereo signal. It offers manual and CV-controlled stereo width, two dimension enhancement effects based on the Haas effect and early reflections, a side high-pass filter for vinyl preparation, and a send/return loop for external M/S processing. Its musical character ranges from subtle stereo glue and width control to dramatic spatial manipulation and faux stereo creation.

Features

  • Hybrid digital and analog Mid/Side stereo image processing
  • L/R to M/S encoding with precision sum/difference matrix
  • M/S to L/R decoding (fully analog conversion stage)
  • IMAGE knob for manual stereo width control (CCW: mono, center: unity, CW: wide to 2xSide)
  • CV input for voltage-controlled stereo width (0-10V range, knob acts as offset)
  • Dimension A effect based on Haas effect with slowly varying inter-channel delay
  • Dimension B effect based on early reflections ER network for spaciousness
  • Mono to faux stereo conversion via Left/Mono input with Dimension effects
  • Side HPF with 300Hz/12dB-oct and 50Hz/24dB-oct settings for vinyl and PA prep
  • Mid Send and Side Send jacks for external M/S processing
  • Mid Return and Side Return jacks with internal send-to-return normalization
  • POSITION knob for L/R output balance trim (+2/-12dB range)

Controls & Jacks (18)

  • Dimension— 3-position slider switch selecting dimension effect: off, dimension a (Haas effect with slowly varying delay), or dimension b (early reflect
  • Side HPF— High-pass filter on side component with three settings: off, 50Hz (24dB/oct), or 300Hz (12dB/oct) for eliminating off-axis low end.
  • Image— Controls the width of the stereo image by applying variable gain to M and S components. Center position (mid+side) does not affect signal. C
  • Position— Adjusts left and right output balance with range limited to +2/-12dB for precision.
  • Goniometer LED M— Goniometer display LED indicating signal strength along vertical axis (channels in phase).
  • Goniometer LED S Left— Goniometer display LED indicating signal strength along horizontal axis (stereo width/side component).
  • Goniometer LED S Right— Goniometer display LED indicating signal strength along diagonal axis.
  • Goniometer LED L Out— Goniometer display LED (yellow) indicating left output signal strength after symmetry adjustment.
  • Goniometer LED R Out— Goniometer display LED (yellow) indicating right output signal strength after symmetry adjustment.
  • Left In— Left channel audio input (AC-coupled). Accepts up to 20Vpp, recommended 10Vpp.
  • Right In— Right channel audio input (AC-coupled). Accepts up to 20Vpp, recommended 10Vpp.
  • Mid Send— Mid component (scaled sum of L and R) available for external processing.
  • Side Send— Side component (scaled difference of L and R) available for external processing.
  • Mid Return— Mid component return path. If unpatched, internally normalized from Mid Send.
  • Side Return— Side component return path. If unpatched, internally normalized from Side Send.
  • Left Out— Left channel audio output from M/S to L/R conversion.
  • Right Out— Right channel audio output from M/S to L/R conversion.
  • Image— Controls the width of the stereo image by applying variable gain to M and S components. Center position (mid+side) does not affect signal. C
