Logarithmic Attenuator with Three Groups
Our Logarithmic Attenuator (AT) features three logarithmic unity-gain attenuators; especially suitable for attenuating audio signals. However, it can also be used to attenuator CV signals.
It is also a passive module; meaning that no power is required for it to function.
