Strymon AA.1 Eurorack Amplifier Attenuator / Level Shifter

The Strymon AA.1 is designed to solve all the issues that arise when introducing guitar gear to the world of Eurorack. Most Eurorack modules output very hot audio signal levels that can easily overload the inputs of effects pedals or computer audio interfaces. And it’s not just the output of the modules: Audio inputs in a Eurorack system also need to receive hot signals. AA.1 amplifies the input and attenuates the output signals to the appropriate levels.

The 1/4″ stereo input amplifies guitar level signals by +18dB, outputting the amplified signal through left and right 1/8″ outputs (use the left output for mono). Left and right 1/8″ inputs attenuate Eurorack level signals by -18dB, sending the attenuated signal through left and right 1/4″ outputs suitable for outputting to guitar level products.
