Duatt 1U is a versatile tool for managing signal levels and offsets within a 1U row. Each channel features a polarity switch that determines how the knob behaves: in unipolar mode, it acts as a standard attenuator (0 to +5V); in bipolar mode, it functions as an attenuverter (-5V to +5V). With no input patched, the module generates a precision DC voltage, allowing you to use the knobs to manually control parameters or provide fixed offsets to other modules.

Channel A includes a dedicated 2x multiplier switch, which doubles the gain of the incoming signal or the internal DC voltage. This is particularly useful for boosting weak modulation sources or reaching higher voltage ranges. Because Channel A is internally summed into Channel B, the module also serves as a two-channel mixer. If you patch into Output A, the signal is removed from the mix, allowing the two channels to operate independently.
