Intellijel Triatt

Triple attenuator, attenuverter, inverter, and DC source

6 HP Eurorack module

The Triatt is a compact triple attenuator/attenuverter utility module that provides three independent channels of signal scaling with selectable polarity, doubling as a DC voltage source when no input is connected. Its musical character is utilitarian and essential — taming modulation depths, inverting control voltages, and mixing signals with precision.

Features

  • Skiff friendly single PCB design
  • Three independent channels: A, B, and C
  • 3-position polarity switch per channel: attenuator, attenuverter, inverting attenuator
  • Linear attenuation
  • Inputs normalled to DC voltage (5V or 10V selectable per channel via rear jumper)
  • Usable as manually variable DC voltage source without any input signal
  • OUT A and OUT B are normalized into C/SUM when unplugged
  • C/SUM output mixes all three channels when OUT A and OUT B are unpatched
  • Plugging into OUT A or OUT B removes that channel from the SUM mix
  • Active/buffered signal processing

Controls & Jacks (12)

  • Channel C Attenuator— Sets the amount of attenuation for the IN A input. Behavior depends on the polarity switch position. Linear attenuation.
  • C/SUM— With no cables connected to OUT A or OUT B, this output is a sum of the outputs of channels A, B, and C. Connecting a cable to OUT A or OUT
  • IN B— Input for channel B. When no cable is plugged in, the input is 5V or 10V depending on the corresponding rear jumper setting.
  • OUT B— Output for channel B. Plugging a cable into this jack removes the output from the SUM mix.
  • OUT A— Output for channel A. Plugging a cable into this jack removes the output from the SUM mix.
  • Channel B Attenuator— Sets the amount of attenuation for the IN B input. Behavior depends on the polarity switch position. Linear attenuation.
  • IN C— Input for channel C. When no cable is plugged in, the input is 5V or 10V depending on the corresponding rear jumper setting.
  • IN A— Input for channel A. When no cable is plugged in, the input is 5V or 10V depending on the corresponding rear jumper setting.
  • Channel A Attenuator— Sets the amount of attenuation for the IN C input. Behavior depends on the polarity switch position. Linear attenuation.
  • Channel A Polarity— 3-position switch: right = attenuator (0V to full signal), middle = bipolar attenuverter (inverted to normal), left = inverting attenuator (
  • Channel B Polarity— Selects attenuator (+) or attenuverter (-) mode for channel B
  • Channel C Polarity— Selects attenuator (+) or attenuverter (-) mode for channel C
