• Passive signal path for unaltered output of the incoming signal
• Can be used in both directions (A/B to Y or Y to A/B)
• A|B switch switches either A or B to Y
• A&B switch switches A and B to Y
• Relay-based soft switching for virtually silent switching
  
• Operation via 9V DC power supply unit (optionally available)
  
  

The KMA Audio Machines ABY is a practical routing tool on the pedalboard that may seem inconspicuous at first, but when used correctly it opens up unimagined sonic possibilities. The extremely useful pedal from Karl-Marx-Allee in Berlin works in both directions, allowing it to be used in a variety of different applications. For example, the KMA ABY can be used to control two different effect chains separately or simultaneously with one instrument; alternatively, two different instruments such as e.g. a guitar and a Bass can be used via the same rig. Although the signal path is completely passive and reproduces the signal unaltered, the KMA ABY uses an active relay-based Soft switching circuit to make switching between different sources as quiet as possible.
