Intellijel Quadratt 1U

Name: Quadratt 1U
Brand: Intellijel

Quad attenuverter, summing mixer and DC source (1U)

28 HP Eurorack module

Quadratt 1U is a four-channel active/buffered attenuverter and summing mixer in Intellijel's 1U tile format. Each channel has a knob and a two-position switch that sets the knob to act as a unipolar attenuator (UNI) or a bipolar attenuverter (-/+). Each input is normalled to a precision +5 V DC source, so with nothing patched a channel becomes a 0-to-+5 V or -5-to-+5 V offset/voltage source. The outputs are normalled to cascade rightward (A into B, B into C, C into D) for instant submixes of two, three or all four channels.

Features

Four active/buffered attenuator-attenuverter channels
Per-channel UNI / -/+ polarity switch
Each input normalled to a precision +5 V DC source
Acts as a quad DC voltage/offset source when inputs are unpatched
Outputs cascade-normalled rightward for instant submixes
OUT B = A+B, OUT C = A+B+C, OUT D = A+B+C+D when downstream jacks are free
Patching an output removes that channel from the downstream sum
Handles audio and CV (audio is a voltage too)
Linear attenuation taper
Intellijel 1U tile format, 28 HP wide
24 mA @ +12V, 23 mA @ -12V, 25 mm deep
