Doepfer A-138m

Doepfer’s A-138m is an excellent means of combining and routing signals in a Eurorack modular environment. Each output is switchable between unipolar and bipolar, where its knobs work as either attenuators or polarizers respectively. There is an internal jumper that determines whether the module’s four controls across the top function as DC offsets when the first input is left unpatched, making it perfect for complex routing and FX applications.
