About This Listing

Shelves brings to Eurorack modular systems something we are all very familiar with: the 4-band parametric EQ typically found in console channel strips. But this time, thereメs CV control! The first band is a low-pass shelving filter, the fourth band a high-pass shelving filter, and band #2 and #3 have full-blown parametric controls with bandwidth (Q) adjustment. All analog.

Shelves will provide a subtler spectral shaping & coloring than standard multimode filters. It is particularly useful in the feedback loop of effects or more generally in feedback patches in which the slightest tonal change has drastic consequences. Or as a novel way of shaping sounds obtained by west-coast techniques. Or as a formant-ish filter. Or to emulate the body of instruments in the context of physical modelling patchesナ

Unlike console EQs, each band is not restricted to a narrow range of frequencies: it can be swept across the entire audio range, from 20 Hz to 20kHz ヨ with unexpected phase cancellations or reinforcements when corrections compete in the same frequency range. All parameters have direct CV control. Global frequency and cut/boost CV inputs allow simultaneous CV control of all channels.

Expander 
Shelves two parametric sections are, behind the scenes, full-blown 12-dB multimode filters. The expander panel gives you access to their low-pass, band-pass, and high-pass outputs.

Voltage controlled EQ with sweepable low-shelf, high-shelf, and two parametric sections.

I/O
  • Scales: all frequency CV inputs: 1V/Oct. All cut/boost CV inputs: 3dB/V.
  • Low-shelf frequency and cut/boost CV.
  • High-shelf frequency and cut/boost CV.
  • Parametric 1&2 frequency, cut/boost and Q CV.
  • Global frequency offset and cut/boost CV.
  • vSignal input.
  • Signal output.
Controls
  • Low-shelf/Parametric/High-shelf correction frequency, 20 Hz to 20kHz.
  • Low-shelf/Parametric/High-shelf cut/boost, -15dB to 15dB.
  • Parametric correction Q, 0.5 to 20 (up to 1000 with external CV offset).
Expansion
  • The parametric sections are realized with state-variable filters, whose high-pass, band-pass, and low-pass outputs are available on a header on the back of the module or through an expander.
Technical characteristics
  • Analog signal path.
  • All inputs DC-coupled.
  • Input impedance 100k (25k for the global frequency and gain CV inputs).
  • Open-source hardware.
  • 16-HP.
  • Current consumption: +12V: 75mA ; -12V: 75mA.
