0606 ISO (600 : 600)

The Kraftwerk 0606 ISO is a compact line-level isolation transformer designed to preserve musicality while subtly shaping tone. It follows the tradition of classic 600:600 line transformers, delivering gentle coloration, smooth transients, and effective isolation in professional and hi-fi applications.
Its flexible winding configurations allow it to be adapted for a variety of impedance-matching and tonal tasks, making it equally at home in vintage-style consoles, modern outboard gear, or reamping setups.
