INVENTORY #58506

BRAND: Doepfer

MODEL: A183-1 & A-183-2

FUNCTION: Eurorack Synthesizer Module

PRODUCT DESCRIPTION: This listing is for a set containing Doepfer A-183-1 Dual Attenuator & A-183-2 Offset Attenuator Eurorack Synthesizer Modules. The Doepfer A-183-1 Dual Attenuator is a compact, completely passive Eurorack module designed to manually scale the levels of audio and control voltage (CV) signals. It is particularly useful for adding level control to other modules that lack built-in attenuators, such as certain VCAs or quantizers. The Doepfer A-183-2 Offset/Polarizer/Attenuator is a compact 4HP utility module designed to manipulate CV or audio signals by adding a DC offset and controlling signal amplitude.

SPECS:

• A-183-1 Specs:
  • Passive Operation: Each of the two units consists simply of two sockets and a 50k linear potentiometer. It contains no active components like buffers or amplifiers and requires no power supply (0mA current draw).
  • Signal Control: Provides attenuation from full level (fully clockwise) down to zero (fully counter-clockwise).
  • Dimensions: The module has a panel width of 4 HP and a depth of 20 mm.
  • Applications: Ideal for taming hot audio signals, adjusting modulation depths, or acting as a manual volume control for headphones.
• A-183-2 Specs:
  • Dual-Function Control: Features a toggle switch to select between attenuator mode (standard signal reduction) and polarizer mode (where zero level is at the center position, allowing for signal inversion).
  • Offset Generation: Adds a constant DC voltage to the signal, adjustable via internal jumpers to ranges of 0 to +5V or -5V to +5V.
  • Dual Outputs: Equipped with two connected output sockets, functioning as a built-in multiple for routing the processed signal to two different destinations.
  • Compact Design: Occupies only 4HP of rack space with a case-friendly depth of 20mm.
  • Power Consumption: 20 mA total (10mA at +12V and 10mA at -12V).
  • Dimensions: Width of 4HP (20mm) and a depth of 20mm.
  • Signal Compatibility: Suitable for both audio and control voltage (CV) signals. 

ACCESSORIES INCLUDED:  

• Eurorack Power Cable
• (4) Eurorack Screws & Washers
