The 1U Duatt from Intellijel is a two-channel mixer, attenuator and attenuator for audio and CV signals. Since the two inputs are normalized to each other, the module is perfectly suited as a mixer, for this purpose each input can be levelled normally or mixed inverted. The Duatt also functions as a dual attenuator/attenuator- i.e. an attenuator or polarizer. Which function is executed is determined by the toggle switch "Uni _ -/+". The third main function is that each channel can act as a manual CV source. The toggle switch determines whether you generate values from 0-5 volts or -5 to +5 volts. This handy feature is useful when you want to move multiple parameters at once in conjunction with a multiple. Activating the middle toggle switch doubles the voltage or level of channel A to be output. Very useful if you want to "translate" for modules that expect 10V control voltage.
