Description

Doepfer A-183-2 Offset/Polarizer/Attenuator Eurorack Module

The Doepfer A-183-2 Offset/Polarizer/Attenuator provides you with a modular platform for the generation of voltage offset, as well as attenuation/polarization for the CV input. This single channel module also features the ability to switch between the attenuator or polarizer function for the input control. At 4HP/20mm wide, the A-183-2 is ultra-compact with a case-friendly depth of 20mm also. The module is equipped with an offset control, switchable attenuation/polarization control, a single input, and 2 outputs.

How The A-183-2 Works

The Doepfer A-183-2 is a simple voltage offset generator combined with a switchable attenuator/polarizer for the module’s CV input. The module is equipped with two outputs, at which a DC voltage appears which can be adjusted using the offset control in the range of 0V to +5V, ot -5V to +5V. An internal jumper is used for selecting between these two offset ranges. Other ranges can be achieved by changing a resistor on the PCB. The DC voltage generated by the offset control is overlaid by the attenuated voltage that is fed to the input socket. The function of the attenuation control can be set using the Att./Pol. toggle switch. When set to Att., the control will work normally as an attenuator. This means zero level when set fully counter-clockwise, and maximum when fully clockwise. When set to Pol., the control will work as a polarizer, with zero level at the central position, right from the central position will add the input signal to the offset voltage, and left from the central position will subtract it. At fully clockwise in polarizer mode, the non-inverted input signal is added with the full level to the offset voltage, and at fully counter-clockwise the inverted input signal is added with full level to the offset voltage. The amplification range for the module’s input is roughly 0 to +1 in attenuation mode, and -1 to +1 in polarization mode

Features Include:

  • Single-Channel Combined Voltage Offset/Attenuator/Polarizer
  • Switchable Attenuation/Polarization Control For CV Input
  • Single Input With Two Connected Output Sockets
  • Offset & Amplification Range Can Be Adjusted With Resistor Change
  • Compact 4HP/20mm Width With Case-Friendly 20mm Depth
