1U Shades /// Mutable Instruments Eurorack Module /// Shades Clone /// Black Panel

1U Shades is a redisign of the Mutable Instruments Shades.

Shades is a multifunction module combines a three-channel active attenuator/polariser, offset generator and small mixer in one unit.

It works with both audio and CV signals. Shades has three channels that can be used as active attenuators or bipolar attenuators. The polarity of each signal is indicated by two-colour LEDs. The inputs are normalised to fixed voltages (0-5V or 0-10V, adjustable with jumpers on the back), so that the channels can be used as offset generators. If no cables are plugged into the individual outputs, the signals are normalised and the module can be used as a mixer.

Audio signals can be mixed, but due to the inverting attenuators, it is ideal for mixing control voltages. The Shades uses low-noise and low-distortion operational amplifiers and resistors with 0.1% tolerances, making it useful for transposing pitch CVs.

The 2020 version has been expanded to include one LED per channel to display the negative portion of the waveform and is visually adapted to the newer modules from Mutable Instruments.
