The u3A is a three channel attenuverter useful for scale, add offset, invert or sum signals. As each input is normalled to +5V, with nothing plugged into the jacks, each knob controls a voltage range from -5V to +5V. Each output is also summed to the adjacent channel on the right when no cable is connected.

Technical specifications:

• 18HP, Intellijel 1U size.
• 30 mm depth.
• Consumption: 30mA +12V; 30mA -12V.
