1010 ISO (10k : 10k)

The Kraftwerk 1010 ISO is a high-fidelity audio isolation transformer, crafted to carry signal with soul. Designed for applications where nuance, warmth, and character are more important than sterile perfection, it evokes the sonic signature of a time when audio was deeply human.
 
Whether used to eliminate ground loops, interface gear, or simply add analog texture, the 1010 ISO honors the musicality of signal flow. It offers multiple winding configurations to adapt to a range of impedance and tone-shaping needs.
