Half a Quadratt (and a little bit more)

A super compact Dual Attenuator, Inverter, Attenuverter, Multiplier, Mixer and DC Voltage Source. The little brother of the mighty Quadratt 1U module with added gain multiplier switch and half the size.

The perfect complement to any module.

Duatt is a dual-channel active/buffered attenuverter and summing mixer. Each channel has a knob, which can function as a unipolar attenuator or a bipolar attenuverter, depending on the setting of its corresponding two-position polarity switch. It’s a versatile and super handy utility module that will find its way into almost any patch you make!

Each input is normalled to a built-in +5V DC voltage source. With nothing plugged into the jacks, each knob controls a voltage range of 0 to +5 V or -5 to +5 V depending on the position of the channel polarity switch.

Channel A’s output is normalled into the output of channel B for mixing duties, and channel A has has a 2x voltage multiplier switch, allowing you to double the voltage sent into Channel A.
