Doepfer A-138f Dual 3-Way Xfade / Mix

The A-138f is a dual 3-way mixer and crossfader module featuring two identical sections. Each section has three inputs (A, B, and C) and a single output, with a central knob allowing you to morph between the three signals. This design enables smooth transitions and creative mixing of audio or CV sources.

Because it's passive, the A-138f doesn’t require power, making it an efficient addition to any Eurorack system.

Key Features:

• Two independent 3-way mixer/crossfader circuits

• Manual blending between signals A, B, and C

• Suitable for audio and control voltage

• Passive design – no power required

• 8 HP wide
