Shelves

OVERVIEW

Shelves is a voltage-controlled signal processor inspired by the EQ section of console channel strips. Just
like many sought-after equalizers, it provides low-shelf, high-shelf, and two parametric tone controls.
Unlike an equalizer, each of these four tone controllers can be swept over the entire audio range; and their
parameters can be freely modulated with control voltages.
Shelves occupies a space between tone-controllers and filters, sometimes achieving sounds reminiscent
of a filter bank. It provides a subtler and less cliché'd way of spectrally altering complex drones or
feedback patches.

INSTALLATION

Shelves is designed for Eurorack synthesizer systems and occupies 16 HP of space. It requires a -12V /
+12V supply (2x5 connector), consuming 75mA from the -12V rail and 75mA from the +12V rail. The red
stripe of the ribbon cable must be oriented on the same side as the "Red stripe" marking on the printed
circuit board.
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired
operation.
This device meets the requirements of the following standards: EN55032, EN55103-2,
EN61000-3-2, EN61000-3-3, EN62311.
