The CPK 220 is a flexible compact microphone cable with a relatively small outer diameter and a high tensile strength due to the integration of additional aramid Kevlar threads. It is also used, for example, as a TT (Tine Telephone) cable or a midi cable.

This patch bulk cable features a cross-section of 2 x 0.20 mm² (AWG 25). The copper conductors are stranded in pairs and surrounded by a spiral shield. The overall cable jacket is made of PVC and available in black, blue and red.
