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
