Get to know them!

The Doepfer A-183-3 Eurorack Amplifier module is a great solution for managing signal levels between Eurorack modules. This simple amplifier can be used for both CV and audio signals, with up to 4x amplification. Use it to increase signal level from lower-output modules, or to attenuate hot signals. Overload LEDs help you ensure your signals stay within the target range. As your modular synth rig grows, Sweetwater highly recommends the Doepfer A-183-3 Eurorack Amplifier as a simple way to manage signal levels.

Amplify low-level signals or attenuate hot signals

Using the Doepfer A-183-3 Eurorack Amplifier is simple - use the three-way switch to select an amplification scale of 1, 2, or 4, then use the Level knob to vary from zero amplification up to the maximum value selected with the switch. With 1 selected on the switch, the Level knob acts as an attenuator, ranging from zero to unity gain. When one of your modules' output is higher or lower than you need it to be, the Doepfer A-183-3 Eurorack Amplifier is the module you need.

Doepfer A-183-3 Eurorack Amplifier Module Features:
  • Amplifier/attenuator module for Eurorack
  • DC coupling allows it to process both audio and CV signals
  • Smart solution for managing signal levels throughout your Eurorack rig
  • Choose between 1x (attenuation), 2x, and 4x amplification ranges
  • Overload LEDs show you when your signal voltage becomes too high (+10V) or too low (-10V)
  • Size: 4hp, 20mm deep
  • Power usage: +20mA (+12V)/-10mA (-12V)
Maintain full control over signal levels in your Eurorack rig, with the Doepfer A-183-3 Amplifier Module.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
