FET Filter Saturating EQ Colour

$79.00

The FET Filter module couples transistor saturation with two tone-shaping equalization circuits. A gentle high-pass filter feeds into a variable mid-range cut/boost. Both EQ stages as well as the FET saturation can be set with jumpers, so you can tailor the curves and texture to your needs.

The unique FET input stage can be set to "Clean" for just a touch of analog flavor, "Dirty" for thicker saturation and transient rounding, or bypassed altogether for clean equalizing.

Features

  1. Discrete FET input
    1. Two bias settings: Clean and Dirty
    2. Bypass via jumper
  2. 6 dB/oct high pass filter: OFF, 72 Hz, 160 Hz, 340 Hz
  3. +/-12 dB variable midrange boost/cut EQ: 330 Hz, 500 Hz, 800 Hz, 1.6 kHz
  4. Class-A biased audiophile grade op pamps
  5. Can be configured as:
    1. FET saturator (no EQ)
    2. High pass filter (no saturation)
    3. Mid boost EQ for warmth or presence
    4. Mid cut EQ for clarity or resonance removal
    5. Filtered distortion device

    Fully assembled, calibrated, and tested by Louder Than Liftoff.

    Colour is a new format for analog audio gear designed for and by the DIY community. We took our favorite sounding analog circuits and put them on modules that are small, affordable, and swappable.

    The Colour format consists of Colours and Palettes:

    Colours are ultra-compact, pluggable analog circuit blocks that impart various types of analog color. Check out our ever-growing selection of Colours. Colours can be designed and released by anyone.

    Palettes provide controls, power, and support circuitry for Colours. We currently offer the Colour 500 Palette and CP5 Mic Preamp with Colour.
