The Intellijel Quadratt 1U is a four-channel utility tile for the Intellijel-format 1U row. It combines attenuators, attenuverters, a cascading mixer and manual DC voltage sources in 28 hp. Intellijel describes it as a shorter, wider relative of its Triatt module. It suits Eurorack users who want quick hands-on control over levels, offsets and polarity without giving up 3U space.
-
Four channels with switchable modes: a two-position switch above each knob sets it as an active unipolar attenuator or a bipolar attenuverter.
-
Normalled +5V source: with no cable in an input, the knob sets a fixed voltage of 0 to +5V or -5V to +5V.
-
Cascading outputs: each output is normalled into the next channel to the right, giving submixes of two, three or all four channels.
-
Active, buffered processing: it attenuates, inverts and mixes external audio or CV.
-
Intellijel 1U format: it is built for Intellijel-standard 1U rows, such as those in Intellijel's 4U and 7U cases.
In a patch, the Quadratt handles routine jobs such as mixing envelopes or LFOs, scaling modulation depth, flipping polarity or adding an offset. Because the inputs are normalled to the internal +5V source, one channel can work as a manual voltage. Sent to several destinations, it becomes a performance macro that moves a group of parameters at once. The manual gives one example: leave Channel A unpatched, set it to the bipolar position, and use it to shift a sequence's note range down into the bass register.
